TRACKING ADJUSTMENT6.4
-NOTE-
Before proceeding with this adjustment, be sure
that the tire pressures are correct and the neutral
adjustment and the steering control rod adjustment
have been completed.
With the machine on a flat level surface, start the
1.
engine, release the parking brake and place the
speed control lever into the speed that will most
often be used.
Squeeze the steering control levers and release the
2.
neutral latch. Slowly release the steering control
levers, allowing the machine to move forward.
WARNING
Before attempting to make any tracking
adjustments, move the speed control lever to
the neutral position, place the blade engagement
switch in the off position, apply the parking brake,
and move the steering control levers into the
neutral position.
If the machine pulls to one side, stop the mower
3.
by placing the steering control levers in the neutral
position. Using the adjustment wrench located on the
left side of the machine, turn the tracking adjustment
nut on the slower side counter clockwise until the
machine tracks straight.
Bring the steering control levers back to the neutral 4.
lock position and check to see that the machine does
not creep forward on the adjusted wheel.
If the machine creeps in neutral, you have moved out 5.
of the neutral band and will have to turn the tracking
adjustment nut clockwise until the machine does not
creep.
Repeat steps 1 and 2. If the machine continues 6.
to pull to one side, stop the mower by placing
the steering control levers in the neutral position.
Turn the tracking adjustment nut on the faster side
clockwise until the machine tracks straight.
