brake lever to the park brake position and check to make
sure wheels are not rotating.
13. If wheels rotate, repeat steps 3- 11.

Drive straight linkage adjustment
It may be necessary to adjust the drive linkage on the mower.
If the mower tracks to the right or left when operating use the
following method to adjust the drive linkage:
1. If the unit pulls to the right, loosen the lock nuts on the
right hand steering rod assembly. If the unit pulls to the
left, loosen the lock nuts on the left hand steering rod
assembly. Figure 4-3
2. Start the engine.
3. While driving, adjust the steering rod assembly by
rotating the center adjustment rod until the tractor tracks
straight. Figure 4-3
4. Stop the machine and shutoff the engine.
5. Tighten the lock nuts on the steering rod assembly. Figure
4-3
6. Repeat steps 2 - 5 for the other side if necessary.
Park Brake Spring Adjustment
Occasionally check the park brake spring adjustment using
the following method:
1. Park the machine on level ground. Disengage deck
clutch, place the H-Bar steering lever in neutral, place
neutral lock/park brake lever in park brake (engaged)
position, stop engine, and remove ignition key. Remove
the spark plug wires from the spark plugs, or, if
applicable, disconnect the negative battery cable.

2. Raise the rear of the mower and block with certified jack
stands. The rear wheels need to be able to rotate freely
and clear of all obstructions.
3. Chock the front tires.
4. Place the H-Bar steering lever in the neutral position and
the neutral lock/park brake lever in the park brake
(engaged) position.
5. Measure the park brake spring. It should be compressed
to the 2.00". If it is not adjust the nylock nut until the
proper spring compression is achieved. Figure 4-4
6. Check engagement of internal park brake pawl by
manually rotating transmission axle in both directions. If
pawl is engaged, the axle should not rotate.
7. Place the H-Bar steering lever in the run position and the
neutral lock/park brake lever in the disengaged position.
8. The washer under the double jam nuts should still be free
to rotate, and have approximately .06" clearance. If not,
re-adjust jam nuts to this dimension.
9. With brakes still in the disengage/run position, verify that
wheels rotate freely without brakes grabbing. If brakes
are grabbing, adjust jam nuts closer to end of brake rod
assembly until wheels rotate freely. Re-engage brake
lever to ensure that brakes are set.
10. Repeat engagement and disengagement as required to
ensure that brakes are set in the engaged position and are
released in the operate (disengaged) position.
11. Brakes are now set.
Belts
Inspect belts frequently for wear and serviceability. Replace a
belt that shows signs of severe cuts, tears, separation, weather
checking and cracking, or burns caused by slipping. Slight rav-
eling of belt covering does not indicate failure, trim ravelings
with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the bot-
tom of the groove. Replace the pulley when this is the case, oth-
erwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt dress-
