(5) Control Linkage

(1) Speed Control Pedal
(2) HST Pedal Rod
(3) Damper
The speed control pedal (1) and trunnion wheel (5) of variable swashplate are linked with the HST pedal rod (2),
HST lever R.H. (4) L.H. (6), HST link rod (7) and neutral cam (8). As the front footrest of pedal is depressed, the
swashplate rotates and forward travelling speed increases. Depressing the rear footrest increases reverse speed.
The roller (9) on the neutral holder (10) is held with spring seats the detent of the neutral cam (8) so that the neutral
cam (8) returns to neutral. Then, the swashplate is returned to neutral with the neutral cam, when the pedal is
released.The damper (3) connected to the HST lever R.H. (4) restricts the movement of the linkage to prevent abrupt
operation or reversing.
