WALK-AROUND
WB140/150
Komatsu backhoe loaders bring together the versatility ofa backhoe loader with the performance of an excavator. Komatsu’sexclusive HydrauMindTM hydraulic system is the ultimate combinationof power and precision creating one of the most productive backhoeloaders in the world.
Increased hydraulic speed during loader and backhoe operationsfor increased productivity
High altitude/high ambienttemperature package available asan option
Improved operator-friendlyaccelerator and parking brakelever design
New loader bucket designfor better penetration into the pileand easier loading of material
1.0 m3 1.3 yd3 multi-purpose loader bucketoffers increased capacity (1.04 m3 1.36 yd3 bucketavailable for WB150AWS)
Improved brake performance withnew 4-wheel braking feature (4th gear only)
Lateral engine air intakefor improved visibility to bucketduring loader operation
Steel reinforced front grilleand tiltable plastic hood for durabilityand ease of service
Komatsu’s new Tier 2 engineprovides for low emissions andexcellent fuel economy

PRODUCTIVITY FEATURES
WB140/150 B A C K H O E L O A D E R S
A powerful Komatsu S4D106-2XFH/2SFATurbocharged water-cooled dieselengine provides output of 65.1 kW 87 HPfor the WB140-2N/WB140PS-2N, andoutput of 70.1 kW 94 HP forthe WB150-2N/ WB150PS-2N/ WB150AWS-2N. Thisengine is EPA Tier 2, EUand Japan emissionscertified without sacrificingpower or machineproductivity. The large pistondisplacement of theseengines, 4.4 ltr 269 in3,ensures high torque andpower, and above all exceptionalreliability.
Tremendous Hydraulic PowerUnder Your Complete ControlWith Proven HydrauMindExcavator Technology
Komatsu’s exclusive HydrauMindhydraulic system is the ultimatecombination of power and precisioncreating one of the most productivebackhoe loaders in the world. Thesystem consists of a single variableflow axial piston pump and an
"intelligent" hydraulic circuit that allowsthe machine to adapt instantaneouslyto the specific operation being carriedout. Superior lift capacities andbreakout forces are achieved withHydrauMind.

pump, means that only the amount ofoil necessary for ensuring highoperating pressure is generated andused. This guarantees greaterefficiency, lower fuel consumption andquiet operation.
Load Independent Flow Divider(LIFD)
Another Komatsu innovation is theLoad Independent Flow Dividerhydraulic valve block. The speed ofeach movement is completelyindependent from that of the others,and the proportions between the variousmovements remain constant even whenthe load resistance varies, resulting inshorter cycle times and greaterproductivity. Engine power is transmittedhydraulically to a transfer case, thenmanually out to the differentials and outto the four driving wheels.

WB140-2N/WB150-2NSwitching between 2WD and 4WD is achieved through an electro-hydraulicsystem. The transmission is operated through a torque converter and a powershift reversing shuttle; the mechanical 4-speed gearbox is synchronized.
The design of the front loader allows for better tensile strength distribution andparallel movements when lifting and lowering the bucket. Due to the linkagegeometry, the greasing points have been dramatically reduced.
