Hydrostatic transmission
Dual-path, hydrostatic transmission provides infinite speed changes up to 8.5 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.
| Travel speed (quick shift mode)* | Forward | Reverse |
| 1st | 0–2.1 mph | 0–2.5 mph |
| 2nd | 0–3.5 mph | 0–4.0 mph |
| 3rd | 0–5.3 mph | 0–5.3 mph |
| Travel speed (variable mode) | 0–5.3 mph | 0–5.3 mph |
*Quick shift speeds are adjustable in the monitor.
Final Drive
In-shoe mounted, axial-piston-type travel motors, with integrated two-stage planetary gear reduction. Compact, in-shoe mount reduces risk of damage by debris. Bolt-on sprocket ring with triple labyrinth seal design.
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 back 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) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.
| Minimum turning radius* | 83 in |
*As measured by track marks on the ground at pivot turn.
