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. 
Minimum turning radius  8'7"  2.61 m 
(As measured by track marks on the ground).     
 
Final Drive   
Two-stage planetary gear integrated into axial piston travel motors. Compact in-shoe mount reduces risk of damage by debris. Bolt-on sprockets for easy replacement.
