FRONT CLUTCH ADJUSTMENT
Burnishing The Clutch
Before the front clutch is used for the first time, it should
be burnished as follows. Also, if mower cut is rough look¬
ing, the clutch may require burnishing. To burnish the
clutch, the mower must be installed.
1. Start the engine and set at full throttle.
2. Pull the front PTO switch out to the on position, leave
for 15 seconds, then push in to the off position.
3. Repeat ten times to burnish the clutch.
Clutch Adjustment
1. Remove the tractor hood by disconnecting the head¬
light coupler and then removing two pins and clip.
2. Use a 0.010” - 0.012” feeler gauge to check front
clutch at three slots (A, figure 28). There should be a
slight resistance as gauge is moved in and out of slot.
If tight or loose, proceed to step 3.
3. Loosen or tighten one of the nuts (B, figure 28) to
achieve slight drag on feeler gauge. Check the other
two slots and adjust accordingly.
NOTE: Adjustment at one location will change adjust¬
ment at the two other slots. Make sure all three locations
have proper adjustment.
LEVELING THE MOWER
^WARNING
Before checking mower, shut off PTO and
engine. Allow all moving parts to stop. Remove
ignition key, then disconnect the spark plug wire
and fasten it away from the spark plug.
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci¬
fied in Checking Tire Pressure.
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Disengage the PTO. Place the mower in mid-cut
position.
4. Arrange the mower blades so that they are pointing
from side-to-side. Measure the distance from the out¬
side tips of the blades to the ground. If the difference
between the two measurements is less than 1/8” (3
mm), the mower is level side-to-side and you can
skip step 5.

5. Loosen the hardware (D, figure 29) securing roller
bar bracket to lift lever bracket. Raise or lower rollers
as necessary to level mower. Tighten hardware and
check measurement again.
6. Position blades front-to-back. Measure from front tip
of center blade to ground and from the rear tip of
either side blade to ground. The front measurement
at center blade should be 1/8” -1/4” higher. To
