LEVELING THEMOWER DECK
Whenleveledcorrectlythe mowerdeck shouldbe
levelsideto side,andshouldbe approximately a 1/8
to1/4inchlowerinthefrontofthedeck.
Sideto SideLeveling
If thecuttingdeckappears to bemowing unevenly, a
sideto sideadjustment can be performed. Adjustif
necessary a sfollows:
• Withthe tractorparked on a firm,levelsurface,
placethedecklifthandle inthetopnotch(highest
position) a ndrotatebothbladesso thattheyare
perpendicular tothetractor f rame.
• Measure the distance fromthe outside leftblade
tip to the groundand the distancefrom the
outside right blade tip to the ground. The
measurements shouldbe equal.If they'renot,
proceed tothenextstep.
• Comparing the two measurements, determine
whether t he left sideof the deckmustbe raised
or lowered.
• Loosen, b utdonot remove, thehexcapscrewon
theleftdeckhanger b racket. Referto Figure 29.
• Levelthe deck by usinga wrenchto turn the
adjustment gear(foundimmediately b ehindthe
hexcap screwjust loosened) c lockwise to raise
the leftsideof the deck,or counterclockwise to
lower theleftsideofthedeck.SeeFigure 29.

• Retighten the hex cap screw on the left deck
hanger bracket when proper adjustment is
achieved.
Front to Back Leveling.
The front of the deck should be approximately 1/8 to
1/4 inch lower than the rear of the deck. Adjust if nec-
essary as follows:
• With the deck raised off of the ground, rotate the
blades so that they are parallel to the frame of the
tractor.
• If the side to side leveling was done correctly,
measuring just the right blade should be
acceptable to attain the correct back to front pitch
of the deck.
• Measure the distance from the front tip of the
blade to the ground and the distance from the
rear tip to the ground. The front distance should
be 1/8 to 1/4 inch less than the rear. If it is not,
proceed to the next step.
• From the front of the tractor, on the rearward side
of the front hanger rod bracket, locate the two
hex jam nuts on the deck front hanger rod. See
Figure 30.

The deck is properly leveled when both blade tip
measurements taken earlier are equal.
• Loosen the two hex jam nuts and turn them away
from the backside of the front hanger rod bracket.
• If the front of the deck was too low, turn the hex
flange nuts on the ends of the front hanger rod
clockwise to raise the front of the deck. See
Figure 30.
• If the front of the deck was too high, turn the hex
flange nuts counterclockwise to lower the front of
the deck.
IMPORTANT: The deck front hanger rod should
be at the front of the slots of the front deck
bracket. If one side of the rod is not at the front of
