Tractor Creeping
Creeping is the slight forward or backward movement of
the tractor when the engine is running at high idle and the
drive control levers are opened out in the neutral position.
If after operating the tractor for some time, it begins to
creep while in the neutral position, adjust the transmission
control rods as follows.
• Place the front of the tractor against an immovable
object (e.g. wall, post, etc.).
• Jack up the rear of the tractor so that both rear wheels
are approximately one inch of the ground.
• With the engine running at high idle and the drive
control levers opened out in the neutral position, and
the parking brake disengaged, check the rear wheels
for rotation.
• If only one wheel is rotating, locate the transmission
control rod beneath the frame at the front of the rear
tire. If both wheels rotate, locate both control rods. See
Figure 7-9.

Ferrule
• Remove the internal cotter pin securing the ferrule to
the transmission control arm and withdraw the ferrule.
Wheel rotation should stop. If it does not, contact your
Troy-Bilt Service Dealer.
• If the rotation stops, adjust the ferrule up or down the
control rod as necessary to align with the hole in the
transmission control arm. Re-insert the ferrule into the
hole in the control arm and secure with the internal
cotter pin.
• If necessary, repeat the previous two steps to adjust the
other transmission control rod.
• Lower the tractor and remove the jack.

Tractor High Speed Tracking
If the tractor tracks to one side with both drive control
levers fully forward, adjust the control levers as follows:
• Check for proper and balanced air pressure in both
front and rear tires. Refill tires if necessary.
• Perform the first three steps in the previous sub-
section, Tractor Creeping, to verify that the tractor
is not creeping. If creeping, adjust following the
instructions in that sub-section.
• Recheck the tracking after making any adjustments to
the transmission control rods.
• If uneven tracking persists, note which direction the
tractor is tracking.
- If the tractor tracks to the right, adjust the control
lever stop bolt on the left side.
- If the tractor tracks to the left, adjust the control
lever stop bolt on the right side.
• Locate the applicable stop bolt on the left or right
console. See Figure 7-10.
Jam Nut
Figure 7-10
• Loosen the jam nut on the stop bolt, then turn the stop
bolt counterclockwise to make it longer. Recheck the
tracking and fine tune the adjustment as necessary.
NOTE: If the stop bolt is adjusted too far, the tracking
problem will change sides. Make fine tuning adjustments
by shortening the same bolt.
• Tighten the jam nut against the console and reposition
the control lever as necessary to make the two control
handles even with each other.
