HYDROSTATIC TRANSMISSION

Dual-path, hydrostatic transmission provides infinite speed changes up to 8.5 km/h 5.3 mph. The variable capacity travel motors allow the operator to select the optimum speed to match specific jobs.

Travel control lock lever and neutral switch.

GEAR FORWARD REVERSE
1st 3.4 km/h 4.1 km/h
2nd 5.6 km/h 6.5 km/h
3rd 8.5 km/h 8.5 km/h

 

FINAL DRIVES

Two-stage planetary gear integrated into axial piston travel motors. Compact in-shoe mount reduces risk of damage by debris. Bolt-on sprocket for easy replacement.

STEERING SYSTEM

Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation. Hydrostatic Transmission (HST) eliminates steering clutches and brakes, providing smooth powerful turns. Fully electronic control enables smooth control. The PCCS utilizes shift buttons to increase and decrease speed. 

Minimum turning radius : 2.0 m
