Features and benefits

New bucket design

A new bucket design helps make this loader up to 7% more productive.

Easy to operate

The Advanced Joystick Steering System (AJSS) and Electronic Pilot Control (EPC) work equipment controls work in tandem to make this wheel loader easy to operate.

Variable traction control system

Maximum rimpull can be adjusted from 100% to 20% to match ground conditions and reduce tire slippage.

Throttle lock

The engine’s RPM can be set to a constant speed for faster cycle times, while the auto-deceleration feature lowers the engine to low idle when an operator command is not sensed, which can help reduce fuel consumption.

Smooth approaches

The modulation clutch controls the tractive effort with the left brake pedal from 100% to 20% of available rimpull output, enabling smooth approaches and speed reduction when loading haul trucks.

Comfortable

A newly designed, low-noise cab features an air suspension, heated seat that increases operator comfort.

Electronically Controlled Suspension System

An electronically controlled suspension system absorbs shock from the boom which helps reduce operator fatigue and material spillage.

SmartLoader Logic

To reduce fuel consumption, SmartLoader Logic senses the power requirement and matches torque output to application.

Integrated payload meter

A payload meter displays a variety of data on the cab’s monitor panel. Payload data can also be accessed remotely with Komtrax Plus.

Two operating modes

Dual operating modes allow the operator to select Power for enhanced engine performance or Economy for lower fuel consumption.

Rearview monitor

A rearview monitoring system features a dedicated color monitor. This monitor can always be on, or only on when the loader moves in reverse.

Easy Maintenance

To promote equipment longevity, onboard diagnostics alert you when your wheel loader needs to be serviced. A swing-out, reversible hydraulic fan and a modular radiator core make cleaning and maintenance easy.
