6. Start the engine and allow to idle for a few minutes to
ensure engine is operating properly.
7. Drive the tractor without a load to make certain all the
tractor systems are functioning properly.

Leveling the Mower Deck
When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1⁄4" lower
than the rear of deck.
NOTE: Check the tractor's tire pressure before performing any
deck leveling adjustments. See the tire side wall for proper
inflation pressures.
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 and using
the power implement lift, 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.)
2. Measure blade-to-ground height at the front tip of the
right blade. To obtain an accurate measure, align blades in
parallel with mower centerline, (i.e. front to back).
3. Measure blade-to-ground height at the front tip of the left
blade. Be sure to measure at the blade tip with the blades
arranged in proper position.
4. Adjust the eyebolt at the left front of the deck so that the
blade-to-ground height at the right front blade tip matches
that of the left front blade tip. This is done by loosening the
jam nuts on the eyebolt and tightening the upper nut to
raise the deck and loosening the nut to lower the deck.
5. The right front blade tip height is fixed so you must adjust
the left front tip to match it. See Fig. 6-6.

6. Once the proper adjustment is made, re-tighten the lower
jam nut.
Front to Back Leveling
1. 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".
2. Loosen the inner jam nuts at the rear left and right of the
horizontal threaded rods. See Fig. 6-7.
