R R420S/R520SAgile, powerful, and ultra-versatile, our compact wheel loadersdeliver optimal performance across a wide range of applications.

Backfilling, dozing, grappling, loading,plowing, scraping—our multi-functional,compact wheel loaders can handle it all.

Compact in size, but not in strength. Kubota wheelloaders can take on the toughest construction,industrial, and agricultural jobs. Features such as quickcouplers and auxiliary hydraulics enable our loaders tooperate a variety of attachments. Fully articulatedsteering and compact size allow for easy navigation oftight spaces. An oscillating body and long wheel basemeans superior stability and strong traction on toughterrain. Not to mention high and long dumpingclearance, unobstructed visibility, low sound level, andmore. The Kubota R420S and R520S wheel loaders cando it all.

CONSTRUCTION

Kubota’s 4-wheel drive lets yououtmuscle challenging terrain,such as mud, sand, and snow.When loose or soft terraincauses one front wheel to loseits grip, the Limited SlipDifferential transfers thatwheel’s power to the oppositewheel to restore traction.

Load Sensing Transmission (LST)

To operate more efficiently, this innovative featureenables our wheel loaders to automatically shift fromhigh speed/low torque to lowspeed/high torque as load conditionsvary. For optimal operation in tightspaces, the travel speed limiterreduces maximum travel speed withjust a touch of a button, whilemaintaining full performance of theauxiliary hydraulics.

Highest dumping clearanceFor easy dumping, even into trucks with high beds, theKubota R420S and R520S have the highest dumpingclearance in their class.

Auxiliary hydraulics—a standard feature With the hydraulic valve and thecontrol lever built-in on both ourmodels, you’ll save time andmoney whenever you need tohook up a hydraulically operatedattachment.

Complies

with Interim

Tier IV!

Powerful and dependable,the R420S and R520S dieselengine deliverssuperior horsepowerand performance. Itoffers low noise andvibration levels,exceptional fuelefficiency, andcomplies with theU.S. EPA’s 2008interim Tier IVemissions regulations.

Clean-runningKubota Engine

100% of available power to both drive wheels.

Versatile wheel loaders that do all the thinkingand working for you, even in the mostchallenging applications.

Versatile 60A alternator For the ultimate in versatility, a 60A alternator provides amplepower for the rotating safety lights (optional), as well as thecabin lights of either model.

Rear attachment capability Unlike most of our competitors, the Kubota R420S and R520Soffer greater versatility with auxiliary hydraulics plumbed toboth front and rear, enabling you to attach a backhoewhenever your job demands it.

Lower sound and vibration To enhance operator comfort, both models utilize a newengine mount design, a helical gear, and an F-shapedfan to significantly reduce overall noise and vibration.

Electric shuttle shifting Increase productionwith on-the-fly shifting.Mounted on thesteering column, thistimesaving, labor-reducing feature letsyou shift from forward toreverse to forwardwithout ever clutchingor braking.

Articulation and frame oscillation For greater stability andmore comfort whenoperating on roughterrain, a unique center-type joint allows for 8° offrame oscillation and40° of articulation ineither direction. Plus,the heavy-dutycomponents ensurelong life operation.

Fully adjustable suspension seat Since every operator’s weight and ideal sitting positionvaries, we created a seat that easily adjusts to provide ahigh level of comfort to a wide range of drivers. Our seatadjusts according to the operator’s weight, plus has hipsupport and reclines. And, because safety is always apriority, there’s an enclosed, retractable safety belt.

Hanging-style foot pedals For increased foot space anda cleaner floorboardappearance, our wheelloaders are equipped withhanging-style foot pedals.

ROPS/FOPS cab andcanopy You’ll work confidently and with peace of mind knowingyou’re protected by our Roll-Over Protective Structureand Falling Object Protective Structure. Forged andattached at the Kubota factory, both the ROPS andFOPS models meet the strictest ISO and SAE standards.

Automatic parking brake This safety featureautomatically engages theparking brake whenever theengine is turned off.Particularly useful when ourwheel loaders are parked onsteep slopes or transportedby truck.

Exceptional serviceability From simple daily maintenance to more complex repairs,a lockable, wide-opening, flip-up engine cover provideseasy access to most areas of the wheel loader’s engine.

Safety Starting System To prevent mishaps, our Safety Start System will notallow the engine to start until the electric shuttle shift is inneutral and the parking brake is applied.
