The front axle oscillates and provides an excellent steering angle for maneuverability but can be locked for better digging and lifting performance. The rear axle is fixed. The transmission is mounted directly to the rear axle for protection from obstacles and optimum ground clearance. 

The high pressure engine and Electronic Power Optimizing System (EPOS) deliver optimum power and fuel efficiency. The design optimizes combustion and torque for faster cycles and maximum results. Choose from Work Mode (digging or trenching) or Power Mode (maximum fuel efficiency) to meet your needs. The color LCD display provides helpful maintenance, history and monitoring information.

An advanced disc brake system works directly on the hub instead of the drive shaft to avoid planetary gear backlash. This eliminates the rocking effect associated with working free on wheels. A new travel motor and transmission control in the driveline provide comfortable travel thanks to increased smoothness and improved hydraulic retarding and gear shifting. 

Enjoy reduced maintenance costs and extended machine life with the durable chassis, strengthened boom and arm assembly, and extended greasing intervals. Easily access the oil filter, air cleaner, fuel filter, radiators and other engine components. The arm grease points are centralized for easy maintenance.
