As the industry benchmark for nearly 20 years, the loader hydraulic system features superior multi-functioning capability enabling operators to lift, swing and rotate the grapple simultaneously without impairing performance.

The precisely tuned pilot controls provide feedback through the joysticks and foot pedals during dynamic operations providing the operator a superior feel of the machine. This results in smoother movements and finer controllability.

Select from three operating modes to meet fuel consumption and production requirements. All modes maintain a consistent system pressure which allows lift capacity and swing torque to remain equal regardless of the mode selected.

The new all down stabilizer function provides uniform stabilizer cylinder force improving machine footing. Combined with a quiet cab, great visibility and a powerful HVAC system keep operators comfortable and productive.

Ground level access of engine, fuel, pilot, case drain filters and the standard electric hydraulic oil fill pump make for safe, easy service. The new grapple rotate flushing reminder ensures oil is circulated back through the filter.

The hydraulic system and components have proven to be the most durable system ever put in a knuckleboom loader. Extreme duty booms and structures are designed to withstand heavy side-to-side delimbing applications day in and day out.
