SHEEP HANDLERSOVINE WRANGLERS TESTED

This month’s Research Report takes a look at sheep handlers and how they can take a fair amount of the strain and stress out of stock work.

As well as manufacturers investing in the handlers and technology, it is pleasing to see sheep producers putting their hands in their pockets to make their farming more efficient and safer. Across the board, manufacturers have noted a resurgence in investment into sheep handlers, yards and shearing sheds.

It’s hard to justify not spending money on sheep infrastructure when the market has such an appetite for meat and wool.

Producers have enjoyed lamb prices of 600-700 cents a kilo dressed weight, mutton prices of 400-500 cents a kilo and a recent jump in

wool prices. The Australian Wool Exchange Eastern Market Indicator is currently hovering around 1500c/kg clean as well.

According to the Kondinin Group’s National Agricultural Survey, 58 per cent of Kondinin Group members run sheep and 30% of those owners use a sheep handler. Interestingly, a further one in six sheep graziers are looking to purchase a sheep handler.

For testing this year, Kondinin Group’s research team of Mark Saunders, Josh Giumelli and Ben White were joined by sheep producer Roger House. Roger is from Kojonup in Western Australia and was on the assessment panel for the last round of sheep handler testing two years ago.

Roger generously allowed us to perform the testing at his property to allow some consistency with the testing protocol including using the same set of yards and the same sheep, which were first-cross maiden ewes with a liveweight of about 48kg and 10 months’ wool growth.

Roger owns a sheep handler and he was our benchmark operator, which means he was the person to perform the animal husbandry tasks for each machine tested. This again helps remove some variability with the testing, as the skill level of the operator was the same for each machine.

Handlers tested were the Peak Hill Handler, TePari HD3, Combi Clamp, Clipex Contractor and the Gallagher Crutch and Dag.

Can ewe handle it?Sheep work can be one of the necessary evils when it comes to handling stock on the farm. Crutching, dagging, wigging, drenching and vaccinating are all important husbandry tasks but when the sheep is 50-100kg or more, it can literally be back breaking.

HOW WE TESTEDThe team or part of the team was present to help set up each handler and the whole team spent time with the supplier to become familiar with the means of operation. A few sheep were run through each handler to make sure the operator was comfortable and working the handler at a reasonable pace, making adjustments to ensure stock flow was maximised.

Once happy with the handler’s set up, the panel put two runs of 20 sheep through each handler, drenching the sheep and recording the time for each run.

As it is not possible to drench a sheep unless it is in the upright position, for the Peak Hill Handler which flips the sheep upside down, the sheep were mouthed, taking the same time as it would to drench.

The panel ensured sheep were always at the entrance to the lead up race for each handler. Prospective buyers should note the lead up race and forcing pens and races play a huge role in maximising sheep flow. Devices such as hock bars and anti-

jumping bars will also dramatically impact sheep flow.

After the timed run for drenching, sheep were again run through each handler to inspect the machines for ease of operation, access to sheep and the ability to undertake other tasks such as dagging, crutching, wigging, foot paring or belly work.

We also video recorded the operation of each handler, so keep an eye out for that on the Kondinin Group’s Youtube channel soon.

Generally, the sheep handlers performed well, being well made and easy to maintain. The Combi Clamp was the clear winner when it came to the timed drench run, clocking 1 minute 23 seconds, which equates to a throughput of about 860 sheep per hour.

At 2 minutes for the 20 sheep, the hourly rate is 600 sheep, which is still very respectable, given the operator is not lifting sheep or having to manhandle them.

But the Combi Clamp will not tip sheep over which can hinder the ability to perform

a full crutch, for example. No one handler can ‘do it all’ and the performance depends on the skill level of the operator, and the ability to keep sheep supplied to the handler.

Once each handler was tested and inspected, ratings were collated to compare build quality, maintenance, ease of operation and adjustability. See Table 1 for a summary of the test ratings and timed results.

Other considerations for the purchase of a sheep handler include its location (permanent or transportable), the ability to use existing weigh scale heads (Gallagher, TruTest or Iconix for example), weighing capability and being able to collect and manage data.

Sheep electronic identification (eID) is already compulsory in Victoria and it will probably only be a matter of time before other states follow suit. Sheep eID tags cost around 30 cents each and the data collected (weight alone for example) can be a valuable management tool. Traceability is also becoming harder to ignore.

There are several other types of handlers on the market, ranging from bulk handlers which raise and lower sheep in a race, to ‘V’

conveyor races which also lift sheep and move them along.

The bulk/race handlers are well suited to large-scale sheep husbandry practices such as drenching, ear tagging and vaccinating.

PROWAY BULK HANDLERThe ProWay Sheep and Goat Bulk Handler is designed and manufactured by ProWay Livestock Equipment. The handler has been developed to minimise labour and stress for a variety of husbandry operations while offering varying holding capacities.

Bringing stock into the Bulk Handler in groups rather than one at a time aims to keep stock flow continuous.

Sheep are ushered into the sheeted race then hydraulically lifted to a comfortable working height, meaning the animals are off

the ground and completely immobilised.Hanging steel supports rise under the

animal’s bellies and hold them as a group. The supports are separated with chains to give enough play for the release of sheep when lowered, but stop smaller stock falling through. Access from both sides of the machine allows a variety of head, mouth and back applications.

The Bulk Handler is available as a permanent structure, or a mobile handler which includes a removable towing frame, suspension and wheels. The permanent Bulk Handler is available in two lengths, (6m and 12m) while the mobile unit is 6m long. Both models have a fixed width of 850mm which encourages sheep flow into the race.

Working capacity varies depending on livestock size and wool, however the 6m unit will hold between 15 and 25 animals at a time. The Bulk Handler is constructed with a galvanised steel frame and all models are fitted with quality hydraulic

components and a 2.2kW electric-hydraulic motor. A 15amp, 240V power supply is required for operation or the Handlers can be powered with an 8kva generator.

Price: 6m Permanent Bulk Handler $16,148.00 inc. GSTMore details: www.proway.com.au

Bulking up: The Proway Bulk Handler lifts sheep in a group.



MURRAY SHEEP HANDLERAnother bulk type handler which uses the raised race principle is the Murray Sheep Handler, made in Western Australia by DE Engineers. Unlike the Proway, the Murray Handler uses a lifting centre section of the race. The centre section, which runs the length of the 7.4m race, works in

conjunction with formed panels on either side of the race. The race is 2.1m wide.

When sheep enter the race, the central section is at ground level. When the race is full, the centre section, which has a triangle profile, is raised. Once raised, the sheep are suspended in two lines, down each side of the race.

The Murray Handler is run by air and does not require power to operate. Sheep can also be tipped onto their backs once raised. The unit is portable as well, with wheels and a tow bar.

Sheep Auto Drafter Plus 3 Way Drafter (G05714)

Fully automated weighing and drafting system that is smoother, quieter and easier to set up and operate than any other sheep drafting product on the market.



HECTONHecton is another ‘clamp and tip over’ style handler, made in New Zealand. Hecton makes the Sheep Handler and Stock Handler and the Stock Handler does not tip the sheep over. The Hecton Sheep Handler is made specifically for crutching and foot paring and allows the operator plenty of

access to the sheep. The clamp is made in two sections; a steel frame with two rubber belts; and a fibreglass panel which the sheep lies on once clamped and tipped over.

The clamping action is a manual mechanism which the operator works by hand. When the sheep is in position, the clamp is pulled towards the operator. The

clamp is a self-locking design which runs along a curved, round steel bar.

Once clamped, the sheep can be tipped over by pulling a switch and a foot pedal operates the entry gate. To release the sheep, the process is reversed and the locking mechanism is released by being bumped away from the operator by hand.

Treated pine timber planks are used for the floor and the unit is available with a lead up race which can be adjusted for width. Construction is hot-dipped galvanised steel, sheet metal panels and fibreglass. The two grab belts can be adjusted forwards and backwards.

A head panel can be opened to provide access to the head of the sheep and the rear belt can also be tipped out of the way for increased access to the rear legs and belly area. Anti-jump bars are standard.

Minimum air requirement is 60psi. The two hinge points at the base of the clamp require some intermittent lubrication and there is no other regular maintenance required on the unit.

Price: $7950 plus GST. The lead up race is $1980 plus GST.More details: www.hecton.co.nz

DANDARAGANSimilar in design to the Hecton handler is the Dandaragan Handler, made in Dandaragan, Western Australia.

The unit is completely manual and while this means no air or power is required, the Dandagaran Handler is a catch-only system,

with no tipping. Sheep are caught by pulling the clamp shut with a hand and the capture mechanism includes a small metal T bar handle which slides over a round bar and locks automatically when the operator lets it go.

The Dandaragan’s construction is simple,

with a panel on either side of the clamp. Each panel has a rubber strip to help with grip when catching the sheep.

Price: $6490 including GST for the clamp and lead up race with dagging door.More details: 0427 514 164

PERKINZ DRENCHMASTERAnother New Zealand-made handler is the Perkinz Drenchmaster. There is a manual model and air-assist model and like other handlers, the unit can be purchased with a lead up race which has anti-backing bars.

With the manual model, when a sheep is caught, the machine can be set so that the operator needs to press a pedal to release the sheep. This allows the operator to walk away with the sheep still in the machine or it can be set to release as soon as the

pressure is released on the machine. The manual model weighs less than 100kg which makes it quite easy to move around. The operator’s hip can be used to close the handler which allows both hands to be free to work on the sheep.

With the air-assist model, it can be used on either side and hence caters for lefthanders. The air-assist unit uses an air switch so there are no electronics. If the compressor fails the machine can still be used in manual mode with no modification.

Prices: Manual model $3267 incl. GST. Air-assist model $5467 incl. GST ex MelbourneWA prices: manual $3800 incl GST. Air-Assist model $6000 incl GST ex Kojonup.

ARROW FARMQUIPArrow Farmquip makes a few different sheep handlers and drafters including the Sheep and Goat Handler (tested in Kondinin Group’s 2015 handler research) and the V Express Sheep Handler. The V Express has two conveyor belts running on an angle to form a V shape, which the sheep walk into. The conveyor frame is tilted upward slightly so eventually the sheep are suspended in the air by the conveyor.

Clipex has made a few refinements to its Contractor model since it was tested by the Kondinin Group two years ago. The design

is the same – the unit is an automated handler which can clamp sheep, side tip and draft three ways.

The Contractor model tested also still has a fold out entry ramp and three-way drafting module. Sensors which are used to open and close the entry door to the clamp are above the clamp, fitted in a large steel frame which swivels over the clamp when in use. When researchers last looked at the Clipex it was noted the sensor housing, which can swing 180 degrees, could pose a head hazard. A metal tab has now been added to help stop and locate the sensor unit for fixing in position for transport.

Once clamped in the Clipex, sheep can be tipped on their side, with the tipping action towards the operator. Front and rear panels on the top of the clamp can be open and shut to provide access to the head and rear of the sheep. This makes wigging and dagging possible as well as some hoof work and further crutching if required.

Our test run for drenching was completed in 2 minutes and 32 seconds and pack up time for the Clipex was 2 minutes and 20 seconds. Clipex recommends a minimum

of 85 psi air pressure and 12 cubic feet per minute air flow for operation and the unit will run on either 12 volts or 240 volts.

Researchers are happy to note the entry gate section folding mechanism is much easier to unpack and store, with functioning small rams working well to help prevent the module free-falling under its own weight.

Clipex gear is made in China however componentry on the Contractor looks well made, including the fittings, hoses, clamps and rams. The control box is located underneath the unit and is well sealed but does provide a slight challenge for access during set up as power is required and the power outlet can be difficult to get to.

There is a large toggle switch also located underneath the Contractor which must be activated during set up and the toggle can be tricky to locate for first time users.

The research panel believes an Anderson plug or similar fitting could be fitted on the frame of the unit, on an upright piece of steel, which would make set up much easier.

The research panel noted there were a few teething problems with the initial set up but as the machine was brand new, these would be alleviated with a little use. For example there was some galvanised paint and welding spatter in a couple of the holes which are used to locate pins in for adjustment.

BUILD QUALITYBuild quality in general is heavy-duty and the entire unit weighs 750kg. Most steel is hot galvanised and the rubber matting used on the clamp walls and floor did a great job of retaining the sheep.

An uncomplicated design makes the Clipex easy to clean down and the manufacturers have added a handy air hose outlet on the ‘off’ side of the unit which can be used to run a hand-held air nozzle.

Three threaded jacks provide a safe footing for the Clipex and while a little slow to operate, they are very handy for finer height adjustments and making sure the end of the entry ramp is touching the ground. The jack covers are a big improvement on the previous unit tested, now made out of stainless steel.

The main control panel is well labelled and laid out, using dials and toggle switches. The clamp width can be adjusted at the base hinge point by locating a spring-loaded pin in one of four holes. The clamp width at the top of the clamp can be adjusted by releasing the pressure on the main ram and relocating the top of the ram with a locking pin. Releasing the pressure on the main ram is easy thanks to a locking collar which simply slides across about 50mm at the base of the ram.

Clamping pressure can also be adjusted by rotating a dial on the control panel and moving the sensors is done by squeezing steel tabs and sliding the sensors along a round bar. Once the squeeze pressure is released, the sensors fix into that position on the bar.

The research panel was impressed by the fact the clamp automatically releases the

sheep once returned to the upright position. Another handy feature is a toggle switch on the rear or flank panel, which is easy to see and operate when the sheep is tipped over.

The whole unit is virtually maintenance free, using nylon bushes/inserts on most moving parts and hinge points. There are water traps for the air and oil systems located at the base of the unit.

The Contractor has a hand-held remote, and a foot pedal control is a $1430 optional extra. Each unit comes with a neat tool kit in a box which houses the hand-held remote as well as a few basic tools and spares.

There is also a safety arm which can be locked into place when accessing the control box, to prevent the cradle and clamp tipping back over on the operator.

The Clipex Contractor tested retails for $28,598 incl GST (ex Perth) which includes wheels, load bars and tow bar. The base

model is $21,900 incl GST which does not have the tow bar, electric jacks and no possible upgrades once delivered.

WHAT WE LIKED Good access to sheep Air outlet for accessories Auto release

WHAT COULD BE BETTER Distribution in WA Pre-delivery needs improvement Initial access to control box during

set up

Blow me down: A spare air hose connection on the off side of the Clipex is a handy addition.

In control: The Clipex’s control panel is well laid out and labelled.



Utilising the weight of the operator and some clever geometry, the Combi Clamp was the fastest throughput sheep

handler we tested for drenching, taking around 1m 23sec for the run of 20 sheep to be drenched.

The modular unit comprises the main squeeze clamp, lead-up race and an optional three-way drafter. The squeeze clamp is actuated by the weight of the operator on a foot panel, meaning the Combi Clamp requires no air or power to use. Catering for left or right-handed operators the unit has adjustments for either configuration.

The squeeze mechanism can be adjusted to accommodate different sized animals in

two ways; for larger adjustments, shifting the hinging point into one of the three sets of hinge hole positions under the handler to shift the actuated side of the clamp module, or for smaller adjustments, lifting and shifting the stationary wall on the operator side into one of three pairs of positions spaced at 25mm increments.

A foot-operated clamp locking bar can be engaged to close the handler or restrain sheep in position without the operator pressing down on the foot panel.

Once the operator gets a feel for the timing and required pressure to restrain and release, sheep flow smoothly through the Combi Clamp. The unit can be set up for weighing by taring off the operator and

clamp module. The required weighing-ready frame is an $825 including GST option.

Animal foot work, wigging and a light crutch is possible with the animal in the standing position, but handlers that tip the animal arguably provide superior operator manoeuvrability with the handpiece for a full crutch. For crutching, a door can be closed on the lead-up race which blocks sheep coming up the race and also has a rubber sweep mat attached to the bottom to clear dags off the handler floor.

Drenching happens in a simple flow with more agile operators we spoke to finding it easy to apply their weight. The Combi Clamp is noticeably quieter than all of other handlers we tested.

MINOR CHANGESThe Combi Clamp has only seen minor changes since our last round of sheep handler testing back in 2015, but all have been to refine the unit for improved usability.

These changes have been made in response to Kondinin Group review and customer feedback. In addition to finer clamp position adjustments, other changes include the addition of a “gadget holder” for ear-tags and tools as well as a sleeve built into the clamping panel for an ear-tag stick-reader to be mounted.

A “lamb cushion”, comprising a smaller piece of gripping rubber running the length of the cradle 150mm from the top rail helps hold smaller lambs in place.

A “classing wall” with open rails to interchange with the fixed panel is also available for side sampling fleeces.

Combi Clamp

Combi Clamp: Having tested the trailer-mounted version in our 2015 test of

sheep handlers, we tested a stand-alone unit as we put units through their paces

this time. Photos: Ben White

Adjustable: Easily sourced trampoline springs provide the clamping resistance. Adjustment for a range of sheep sizes is via a series of three hole settings under the machine. Finer adjustments can be easily made by shifting the clamping panel position.



The frame is predominantly 25mm Square Hollow Section (SHS) 2.5mm wall hot-dipped galvanised steel. The operator platform is perforated aluminium and the cradle and lead-up races are aluminium checker-plate.

We chipped the Combi Clamp in our last review for having un-plugged steel sections, suggesting some cut cross-sections would be better capped after the galvanising process to avoid any sharp edges in manufacture or use. While the open section allows good galvanising penetration and drainage, we still believe the finish is superior on a capped section.

Plastic panels on the Combi Clamp are UV treated, recycled plastic while rubber grip surfaces are round-hay-baler belt.

Springs used in the clamping module are standard size trampoline springs ensuring parts are easily sourced if required.

Maintenance is as simple as cleaning given there is no lubrication points on the Combi Clamp. Clean down is simple with removable panels providing simple access to all areas likely to trap dust from operation in the yards.

With the main clamp module weighting just 120kg, unpacking and setup for a single person is possible. It requires the operator to lift off the lead-up race and doors before rolling the frame up lengthways for wheel removal before rolling back into position and fitting doors and baulk rails on the lead-up race for operation. Pack up ready for transport took a shade over three minutes onto the optional $775 wheel kit suitable for on-farm transport.

If needing to shift between farms, the road-ready trailer-mounted Combi-Clamp unit is available for $17,000 including GST. For more details on the road-ready trailer refer to our report in Farming Ahead no. 282, July 2015.

A standard Combi Clamp costs $7260 including GST in the eastern states and an additional $200 in Western Australia. A three-way manual draft is an additional $1210.

WHAT WE LIKED Clever engineering No power required Quiet

WHAT COULD BE BETTER Probably requires two people to

operate (clamp and push up) Cut section profiles could be capped

for superior finish

Wand pocket: The addition of a sleeve for ear-tag readers to sit is simple but effective.

Catching sheep early as they come through permits a light crutch with a door on the lead-up race blocking sheep running through. Catching animals later as they move through the cradle allows simple front foot paring or drenching once the operator becomes familiar with the machine.



Gallagher’s Crutch and Dag is a relatively simple and robust platform which is available in either manual or automatic catch

versions. Unlike other handlers Kondinin Group tested, the Crutch and Dag has a top clamping action, which hinges the clamp from the top, forming a V-shape.

This works well and prevents any chance of the sheep sitting down as the clamp is actuated. A pneumatic entry shut-off gate meters the flow of animals into the clamp.

The automatic catch version tested uses a single electronic eye mounted above the animal, which is adjustable back and forth to fine-tune catching for different size animals. The entry shut-off gate is triggered simultaneously as the animal is captured, and opened as the clamp is released. The gate opens far more slowly than it shuts, which slightly restricts the flow of animals into the clamp.

During testing, the Crutch and Dag averaged two minutes and 23 seconds to drench 20 sheep, but this was cut to 1.50 with the entry cut-off gate disabled.

The clamp is fast-acting thanks to the rear-mounted pneumatic cylinder, and all surfaces are lined with rubber matting, aiding capture. The floor, including the lead-in and exit ramps are also rubber-lined, aiding grip and reducing noise. While the entry ramp is steep, it did not appear to impede the flow of animals into the clamp.

The Crutch and Dag is simple to operate and controls are straightforward, consisting of buttons to manually catch and release, and to tip the clamp. We liked the clamp button mounted down on the entry race, which would help when a single operator is using the unit. Push/pull knobs for tipping

the clamp are easy to access with the cradle in both positions.

Tipping the clamp presents the animal at a comfortable height, although this is not adjustable to cater for different sized operators. A large flank/belly flap can be opened via pneumatic cylinder, while a head flap is manually operated and needs to be chained back in the open position. In general, the Gallagher unit provided great access to the animal for dagging, a full crutch or work in the pizzle area.

The release of the animal from the tipped position is not automated, which would improve throughput slightly. When the animal is tipped back to the vertical position, the release button still needs to be pressed to release the animal and open the entry gate.

CRANKYAdjustment for different sized animals is via a crank handle at the top of the cradle which adjusts the width of the clamp. But the crank handle does swing a little close to the operator as the cradle is tipped. An air regulator is used to adjust clamping pressure, and minimum air requirement is 12cfm.

We liked the robust construction and hot-dipped galvanised finish, but felt the large pneumatic tipping cylinder gets in the way of the operator moving from the front to rear of the animal. The cylinder is mounted on an outrigger, which no doubt aids stability of the unit. The handler sits on two pipe rails, which do allow it to be manoeuvred by skidding it into position if the wheels are removed.

Robust: The Gallagher unit is well made with extensive use of heavy-duty fittings. Photos: Ben White



Setting or packing up the unit is at least a two-person job, as the handler needs to be tipped up to remove the wheels and axles.

The trailer yoke can be used for additional leverage, but someone must hold it in the raised position as the 14" wheels are inserted or withdrawn.

Ramps fold into the unit and are secured with chain and D-shackles, which is a bit fiddly when holding up the entry ramp. With a few helpers, pack-up was achieved in a good time of three minutes.

The unit does have several grease nipples which require periodic attention. Clean-down is easy, and all electrics are mounted on the sides of the unit, not underneath the platform.

The price is $17,600 including GST, as tested.

In our 2015 round of sheep handler testing, this revision of the Peak Hill Handler was not available for testing as it was undergoing

alterations. Instead, we tested the Peak Hill Immobiliser, which is still available and largely remains unchanged. See the review in Farming Ahead no 282, July 2015.

The Peak Hill Handler features a clamp and rotate mechanism where compressed air and the floor plate actuated valve are used to detect the animal as it walks into the one of

the two cradles, before clamping the animal and closing the rear door. This allows the operator to rotate it when ready. The two cradles counterbalance and while one sheep is held in the clamped position, the other can be worked on before rotation, release and the process can then be repeated.

While sheep shouldn’t be drenched in the reclined position, for the sake of comparison, using the Peak Hill Handler took around three and a half minutes to process the standard 20 sheep.

Air requirement is 550-620kPa and 226litres per minute (80-90psi and eight CFM). The rotation is air assisted with adjustable force and speed and requires the operator to unlock the rotation with a top handle and initiate the rotation.

Releasing a sheep in the cradle in the reclined position is possible by using a foot to actuate the release.

The Peak Hill Handler is the only handler we tested which inverts sheep, presenting their bellies to the operator and permitting procedures including ultrasound pregnancy testing.

A large red kill-switch to prevent rotation is easily accessible and instruction decals explaining operation are clearly marked and easy to understand.

In terms of adjustment the cradle offers over 300mm of height travel via a rotating handle to accommodate larger frame animals. Clamp position can also be adjusted via 3-pins or for fine adjustment using a supplied spanner.

Using the Peak Hill Handler was relatively simple once adjusted to suit the size sheep we were running through it. There were some concerns about potential for operator injury if needing to adjust sheep position if the clamp had not yet been actuated but this is no different to any of the automated handlers.

We also noted that on occasion, sheep in the lead-up race pushing their heads up to the top of the opening side of the baulk gate could get their noses into the rotation path of the cradles.

Peak Hill Handler

Balancing act: After a redesign two years ago, the

Peak Hill Handler utilises two counterbalanced clamp rotation

cradles and only requires compressed air for operation.

Recline time: The Peak Hill was the only unit tested that inverts sheep into a recline position allowing simple pregnancy testing and good access for crutching.



EXCELLENT ACCESSCrutching in the cradle is simple with excellent access and hock-bars hold either or both feet in place if needed.

Construction is predominantly riveted laser-cut galvanised sheet metal and electroplated steel with robot-laid welds. Being laser-cut, the assembly is precise and neatly finished.

Utilising the weight of the animal for actuation is a clever function of the Peak Hill unit which uses the feature to control clamping and door actuation in the handler but also in the lead-up race.

Height of operation is adjustable in 50mm increments to suit a range of operators.

From a maintenance perspective, oiling of the main pivot points is simple to access but all other pivots are bushed in Teflon. An access panel at the front of the machine houses controls and a shock-absorber to soften the rotation.

To manoeuvre the handler, a set of handles fold out allowing the operator to lift one end and shift the unit which sits on quad-bike tyres. The wheels can then be removed, ideally a two person operation without the optional transport kit which uses electric actuators to jack the cradle up.

Pack-up time for the 250kg unit was around three and a half minutes including fitting the drawbar and quad-bike wheels.

An optional drafting module is also available and load cells can be mounted

under the four legs of the unit for weighing operations.

The Peak Hill Handler costs $13,530 including GST. The wheel kit and draw-bar is an additional $1100.

WHAT WE LIKED Access to the sheep Well built Adjustability

WHAT COULD BE BETTER Baulk gate allows some intrusion of

next-up sheep into rotation zone

Clean design: The Peak Hill Handler uses laser-cut galvanised sheet metal and electroplated steel in construction with robotic welds. Maintenance requires only the lubrication of the main pivot but all other pivot points are nylon bushed.

Clamped: Floor plate actuation of the clamp and

doors uses the weight of the animal for actuation.



The TePari HD3 is an all-in-one, modular handler which can be used for a variety of sheep husbandry tasks, with the ability to

catch and tip sheep.The HD3 model tested was fitted on a

trailer unit which comes complete with three-way auto drafter, lead up race and the clamping unit. Clamping is from a pivoting, air-operated panel and air is also used to function the entry gate and three-way drafting mechanisms.

A minimum of 12 cubic feet per minute (340 litres per minute) of air volume is required, along with 90psi (620kPa) of air pressure. The unit can run off 12-volts or 240 volts.

The TePari was one of the easiest handlers to set up, requiring a few pumps of a jack handle to lift one end of the race up, enabling the stub axles to be removed. Once the wheels are off, all that is required to complete the set up is plugging in power and air leads.

The axles on the TePari have a rubber torsion system which provides some shock absorption during transport. The jacking system is a welcome improvement from the last testing round.

At a shade over one tonne in weight, the TePari was the heaviest unit tested however it was also by far the easier to set up, with

everything in place, ready to go once the wheels were removed. Similarly, pack up is a cinch, and only took 2min 11 seconds.

Adjustment is simple when it comes to varying the clamp panel pivoting position as the panel can be moved into one of five positioning holes at either end of the clamp. This also provides the ability to taper the clamp to suit different sizes and shape of sheep. The clamp pressure is adjusted by a dial on the control panel.

With the clamp adjusted, the functionality of the entry gate and release mechanism can then be altered by means of four sensors or electronic eyes which are held in place by magnets on the operator side of the clamp.

Another handy improvement is a slight curve or bulge in the rubber clamp wall, on the operator’s side at the top of the panel. The strip of rubber helps to clamp the sheep and keep it in place when tipped over.

EYE SEE ALLWith four sensors to locate, it can take some time to get them in the right position but the electronic eyes allow for accurate release and clamping functions. There are two blue-coloured eyes and two black-coloured eyes.

There are also two rails for the sensors to be located on – a lower and upper rail, to allow for sheep entering the clamp with the head down or up.

Adjustable: The lead up race on the TePari included easily adjustable side panels.



The black sensor eyes are used for the catching mechanism and the blue sensors are for sensing there is an animal in the unit and to close the entry gate. Ideally, one of the green sensors should be covered by the sheep when it’s in the unit (so pretty much in the middle of the rail).

There is very little maintenance required and no lubrication is necessary. Build quality is at the top of the tree in terms of the handlers the Research panel inspected. The control box looks well made and well sealed however there are quite a few external connections on the box, which is located at the base of the unit, which could be prone to damage and dirt inclusion. The air exhausts into the bottom of the race and there is extensive use of rubber on the gripping surfaces of the clamp. The rubber is a ripple pattern.

Snuggly-fitting polyethylene panels are used throughout the hot-dipped galvanised frame which is also well constructed with the use of steel tubing, rounded at the corners.

A handy addition to the TePari is an operator platform which keeps the operator out of the dirt and mud. Access to the sheep is good once tipped, but there are no head or flank panels to allow extra room for pizzle work or wigging, for example.

And once tipped, the control panel which uses toggle switches is out of view of the operator. Our 20-sheep drench run was a respectable 2 min 7 seconds. When operating the TePari, there are three modes of action.

Mode 1 is a standard set up where the sheep is clamped and weighed. When the clamp is released the entry gate is not opened to let the next animal in until the

green sensor eyes are clear. Mode 2 is for faster flow and still clamps and weighs the sheep. The sheep is clamped and weighed and when the clamp is released, the entry gate is immediately opened to let the next animal in.

In mode 3, continuous flow can be achieved. This mode effectively disables the entry gate completely and is better used if only the occasional sheep needs to be dagged or drafted off.

A hand-held remote is available and a foot pedal control is an extra $450.

The HD3 handler with side tilt and loadbars is $23,000 incl GST and the trailer unit is an extra $7000 incl GST.

WHAT WE LIKED Build quality and finish Access to top/back of sheep Ease of setting up and packing up

WHAT COULD BE BETTER No head panel Control panel switch access when

clamp tipped

Hands on: In the upright position the control panel is easy to follow however when tipped over, it is hard to see. An operator’s platform is a great idea.

Neat: The TePari HD3 tested required minimum effort to set up and pack up, with everything in place once the wheels were removed.
