Hydrostatic Transmission (HST) operation
The ground speed of tractors equipped with a hydrostatic
transmission is continuously variable, from zero to full
rated speed in each range. Speed is controlled by the
HST forward (A) and reverse (B) pedals located on the
right-hand operator’s platform.

gine speed is above 1500 RPM.
3. Place the range gear shift lever (3) in the desired
range.
4. Depress the brake pedals (2) and disengage the park
brake lever (1) (8) .
