38 Tuff Torq Model K61A Hydrostatic TransaxleBelts and Linkage
Hydrostatic Control Linkage
Description and Operation
The hydrostatic control pedal assembly has a forward
and reverse pad and is fitted to the cross shaft, C, for
rotation. One end of the control rod, D, is attached to the
pedal assembly; the other end is attached to the
transaxle control arm, E. The ends of the control rod are
threaded.
When the pedal is depressed, the control rod moves the
transaxle control arm. When the pedal is released, the
transaxle control arm’s internal spring deactivates the
control rod, returning the transaxle to the neutral position.
Lubrication
Grease the hydrostatic control pedal after every 50 hours
of operation.
Pedal Adjustment
Remove the rear fender and seat assembly.
Take out the two fuel tank mounting bolts. Remove the
tank and set it to the left side of the tractor.
Loosen the jam nut and remove the bolt from the rear rod
end of the control rod, F (where it fastens to the transaxle
control arm, E).
Adjust the rear rod end, F, of the c ontrol rod, D, so that
the rear edge of the control pedal reverse pad, B, is 1.25″
(32mm) from the footrest.
