Troubleshooting, Adjustment & Service

If the tractor “creeps” while the ground speed control 
levers are locked in NEUTRAL, then it may be 
necessary to adjust the linkage rod.

 1.  Disengage the PTO, engage the parking brake 

and turn off the engine.

 2.  There are three (3) nuts on the linkage rod.  The 

first two are to be used together to turn the rod 
and the third (towards the front of the machine) 
is used to lock the rod in place.  Loosen the jam 
nut that locks against the clevis (B, Figure 32) and 
turn the linkage rod (A) to adjust.  If the machine 
creeps forward, turn the rod CLOCKWISE (while 
standing at the rear of the machine, facing 
forward), if the machine creeps backward, turn the 
rod COUNTER-CLOCKWISE.

 3.  Lock the jam nut (B) against the clevis when 

neutral is achieved.

If the rider veers to the right or left when the ground 
speed control levers are in the maximum forward 
position, the top speed of each of these levers can 
be balanced by turning the adjustment bolt(s) (A, 
Figure 31).  Only adjust the speed of the wheel that is 
traveling faster.

 1.  Loosen the flange nuts.

 2.  turn the top speed adjustment bolt COUNTER-

CLOCKWISE to reduce the speed.

 3.  Retighten the flange nuts when adjustment is 

complete.
