Redesigned Cab

Operator station is spacious and comfortable. It features extra legroom, additional storage and adjustable seat. A premium cab with a larger monitor and a heated/ventilated seat is optional.

Hybrid Engine

Purpose-built four-speed hybrid-electric transmission with EPA Tier 4/EU Stage V PowerTech™ engine to squeeze the most from every drop of fuel.

EH Controls

Control up to six functions without letting go of the ergonomically designed joystick. Program two-multifunction buttons on the bucket lever to handle any of up to 10 functions.

Buckets & Linkage

New bucket and linkage designs improve load leveling, material retention and visibility. Lift path on all Z-Bar linkages is now near parallel.

Ground-Level Service

All daily service points including fuel are conveniently grouped on the left side of the machine at ground level, for easy access.
