Power Train

The Cat® 3508B turbocharged EUI diesel engine is Tier 2 compliant combined with ADEM™ II and the Impeller Clutch Torque Converter with lockup clutch provides smooth shifting with direct drive efficiency, while the Rimpull Control System matches power to ground conditions.


The 854G features a box-section rear frame and two-plate front frame design, providing strength and stability. Together they provide resistance to dozing shocks and stresses, absorbing shock loads and twisting forces.


The invisible forces behind the mobility and versatility of the 854G are two, independent hydraulic systems and load sensing steering.

Operator Station

High levels of efficiency and comfort come from the STIC controller and state-of-the-art cab that features a wide range of viewing, low sound levels, improved ventilation and easy entry and exit.

Blades and Blade Controls

Choose from a number of different blades with replaceable, bolt-on cutting edges and bottom wear plates that protect the blade, resulting in longer life. A single lever hydraulically controls all blade functions.


Maintenance jobs are easier with ground level access to major service points. Large engine doors, rear access stairs and convenient service platform with large doors enhance servicing.
