| Komstat Hydrostatic Transmission
|
|
| Dual-path, hydrostatic
transmission provides infinite speed change up
to 5.3 mph/8.5 km/h. The 3-speed variable capacity travel motors allow
the operator to select the optimum speed to match specific jobs.
Gearshift lock lever and neutral safety switch prevent machine from
starting accidently. |

| 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 to make a left turn. Tilt it to the right for a
right turn. Tilting the joystick fully to the left or right activates
counter-rotation. Hydrostatic steering eliminates steering clutches and
brakes, providing smooth powerful turns. A PPC valve integrated into
the steering circuit facilitates smooth, shockless control. The PCCS
utilizes shift buttons to increase and decrease speed. |
