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 lift
pedal position the mowing deck into the 4" 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 parallel with the tractor.
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 centerline.
The blade-to-ground height at the rear of the blade tip
should be 1⁄8" to 1⁄4" 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" if cut height is below 1-1⁄2".
3. Loosen the jam nuts at the rear left and right of the deck
eyebolts. Refer to Figure 6-2.
4. Start at the rear right to raise the rear of the deck, tighten
the upper jam nut to raise the deck or loosen the upper
jam nut to lower the rear of the deck.
5. Adjust the jam nut at the rear left to take the "slack" out of
the threaded rod.
6. Tighten both lower jam nuts 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 on the eyebolt. Loosen the jam nuts
and tighten the upper nut to remove "slack".
8. In many cases it will be necessary to adjust deck height using
both eyebolt 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.
Deck Wheels
WARNING!
discharge opening of the cutting deck.
NOTE: The deck wheels are an anti-scalp feature of the deck and
are not designed to support the weight of the cutting deck.
The mower deck cutting height can be set using the tractor's
deck lift pedal. The deck heights range from 1" to 5". The deck
gauge wheel position should be approximately 1⁄4 to 1⁄2" above
the ground when the deck is set in the desired height setting.
Using the lift pedal, set the deck in the desired height setting,
then check the gauge wheel distance from the ground below. If
necessary, adjust as follows:
1. Visually check the distance between the front gauge
wheels and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If more than
1⁄2" above the ground, they should be lowered.

2. Remove the flange lock nut and carriage bolt securing the
front deck wheel and spacer to the deck. Remove the wheel
and carriage bolt. Refer to Figure 6-3.

3. Determine which index hole will give the deck wheel a 1⁄4"
to 1⁄2" clearance with the ground.
4. Insert the carriage bolt through the appropriate index hole
in the deck wheel bracket, through the spacer, the deck
wheel and out the other side of the bracket.
5. Note the index hole of the just adjusted wheel, and adjust the
other deck wheel to the same height as instructed in step 3.
Parking Brake Handle
The parking brake handle should engage with moderate force.
The brake cable should not require adjustment, but if necessary
proceed as follows:
NOTE: There is a cable for each of the transmissions, be sure to
adjust both cables.
1. Locate the brake cable housing nuts on the outside of the
frame and to the inside of the rear tires. See Figure 6-4.
