Tracking Adjustment
-IMPORTANT-
Before proceeding with this adjustment, be sure that
the tire pressure in the three tires is correct, that the
caster wheels turn freely, and that the two
transmission drive belts are adjusted for the correct
tension.
The mower tracking should be adjusted if during low
speed the mower pulls in one direction and then pulls in
the opposite direction as you go faster.
1. If at full speed the mower pulls right, it is an
indication that the left wheel is turning too fast. To
adjust this condition, loosen the lock nut securing the
swivel joint (N, Figure 6-6) to the left hand control
lever. Move the linkage outward in the slot. This
will lengthen the control arm and cause it to stroke
the pump less, slowing down the left wheel.
2. If at full speed the mower pulls to the left, it is an
indication that the left wheel is turning too slow. To
adjust this condition, loosen the locknut securing the
swivel joint (N) to the left hand control lever. Move
the linkage inward in the slot. This will shorten the
control arm and cause it to stroke the pump more,
speeding up the left wheel.
Steering Handle Adjustment
-NOTE-
Changing the Neutral Adjustment will move the
handle locations.

4. Raise the seat far enough to gain access to the control
linkages, but not far enough to contact the control
levers with the seat bracket. Support seat bracket in
the raised position.
5. Loosen the two jam nuts (K & L, Figure 6-6) on the
left control linkage. Turn the turnbuckle (M) until a
gap of 3/4 inches is obtained between the handle and
the frame. Tighten the two jam nuts (K & L).
6. Loosen the two jam nuts (N & P) on the right control
linkage. Turn the turnbuckle (Q) until the right
handle is in line with the left handle (Figure 6-6).
Tighten the two jam nuts (N & P).
Check for a 3/4 inch gap between the control levers and the
frame (Figure 6-7). If this gap is not correct between
either handle, adjust the gap as follows:
1. Shut off the mower’s engine and engage the parking
brake.
2. Tilt the mower deck and lock it in place with the two
deck prop rods. Refer to Section 4 for the correct
procedure.
3. Remove the two deck springs and swing the deck
spring bracket up. If this is not done, the bracket will
contact the control levers when the seat is raised.
