DECK LEVELING
Note: Check the mower’s tire pressure before performing any deck leveling
adjustments. Refer to Tires for information regarding tire pressure. Always level the
deck side-to-side before front to rear.
Side-to-Side Leveling
1. Park the mower on a flat paved surface, engage the parking brake, shut off
the engine, remove the key from the ignition switch, disconnect the spark
plug wires, using the deck height index position the mowing deck into the 4”
(10.2 cm) height of cut position (the 4” height of cut position is recommended
in order for one to see and obtain a measurement. Any height of cut position
is acceptable as long as a proper measurement can be taken) and rotate both
outside blades so that they are perpendicular with the mower.
2. Measure the distance from the outside of the left blade tip to the ground
and the distance from the outside of the right blade tip to the ground. Both
measurements taken should be equal. If they’re not, proceed to the next step.
3. Adjust the eyebolt (a) at the left front of the deck so that the blade-to-ground
height at the right outside blade tip matches that of the left outside blade tip.
This is done by loosening the jam nuts (b) on the eyebolt (a) and tightening the
upper jam nut (b) to raise the deck and loosening the jam nut (b) to lower the
deck. The right outer blade tip height is fixed by the right, front eyebolt (a) so
you must adjust the left outer tip to match it. See Figure 27.

4. Once the proper adjustment is made, re-tighten the jam nuts (b).
Front-to-Back Leveling
1. Park the mower on a flat paved surface, engage the parking brake, shut off
the engine, remove the key from the ignition switch, disconnect the spark
plug wires, using the deck height index position the mowing deck into the
4” (10.2 cm) height of cut position (the 4” (10.2 cm) height of cut position is
recommended in order for one to see and obtain a measurement. Any height of
cut position is acceptable as long as a proper measurement can be taken) and
rotate both outside blades so that they are parallel with the mower.
2. Measure the blade-to-ground height at the right rear blade tip. Again be sure
to measure at the blade tip at the rear of the right blade when aligned along
the mower center line. The blade-to-ground height at the rear of the blade tip
should be 1⁄8” to 1⁄4” (3.2 to 6.4 mm) higher than the front tip. This is referred
to as blade pitch. The same height difference should be true for the left blade,
measured front and back. The pitch should not exceed 1⁄16” (1.6 mm) if cut
height is below 1-1⁄2” (3.8 cm).
3. Loosen the jam nuts (b) at the rear left and right of the deck eyebolts (a). Refer
to Figure 27.
4. Start at the right rear to raise the rear of the deck, tighten the upper jam nut (b)
to raise the deck or loosen the upper jam nut (b) to lower the deck.
5. Adjust the jam nut (b) at the left rear to take the “slack” out of the threaded
rod.
6. Tighten both lower jam nuts (b) to secure the deck adjustment.
7. The final adjustment would be to take the “slack” out of the left rear linkage if
the rear of the deck was raised by adjusting the jam nuts (b) on the eyebolt (a).
Loosen the jam nuts (b) and tighten the upper jam nut (b) to remove “slack”.
8. In many cases it will be necessary to adjust deck height using both eyebolt
(a) adjustments and pitch adjustment to achieve the correct blade-to-ground
heights. If you remember that the front right blade tip adjustment is fixed and
you level to that height, adjusting the decks will be simplified.
Service
SERVICING ELECTRICAL SYSTEM
Fuse
The 25 amp fuse holder is located on the right side of the mower frame under the
control panel. The fuse is a standard plug-in type automotive fuse. Always use
the same capacity fuse for replacement. Check the 25 amp fuse for any electrical
problems.
If you have a recurring problem with blown fuses, have the mower’s electrical system
checked by your Service Center or Dealer.
SAFETY INTERLOCK SYSTEM & SWITCH OPERATION CHECKS
The following operational checks should be made daily with the mower on a flat
surface and the wheels blocked to prevent unintentional movement of the mower:
PTO Switch
1. Stand on the operator’s platform. With the drive control levers in the neutral
position and the parking brake engaged, engage the PTO switch by pulling up
on the knob and try to start the engine. The engine should not start. If it does,
the PTO switch must be replaced. See your Service Center or Dealer.
2. If the engine does not start, disengage the PTO by pressing the knob down and
start the engine. Now engage the PTO and the blades should rotate.
3. If the blades do not turn, the PTO switch must be replaced, the platform switch
must be replaced or the electric PTO clutch must be repaired. See your Service
Center or Dealer.
