LEVELING THEMOWER DECK
Whenleveledcorrectlythe mowerdeckshouldbe
levelsideto side,andshouldbe approximately a 1/8
to 1/4inchlowerinthefrontofthedeck.
Sideto SideLeveling
If the cuttingdeckappears to bemowing unevenly, a
sideto sideadjustment can be performed. Adjustif
necessary a sfollows:
• Withthe tractorparked on a firm,levelsurface,
place thedecklifthandle inthetop notch(highest
position) a ndrotatebothouterblades sothatthey
areperpendicular 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 tothe nextstep.
• Comparing the two measurements, determine
whether t he leftsideof the deckmustbe raised
or lowered.

Levelthe deck by usinga wrenchto turn the

the left sideof the deck,or counterclockwise to
lower theleftsideofthedeck.SeeFigure 31.

• The deck is properly leveled when both blade tip
measurements taken earlier are equal.
• 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
outer 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, loosen the outer
nuts on the deck front hanger rod, and turn them
away from the inner nuts. See Figure 32.

• If the front of the deck was too low, turn the inner
hex nuts clockwise against the hanger bracket to
shorten the front hanger rod and raise the front of
the deck. See Figure 32.
• If the front of the deck was too high, turn the hex
nuts counterclockwise to lengthen the front
hanger rod and 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
its slot, turn the inner hex nut on that side until
rod just touches the front of the slot. Then re-
measure and re-adjust the front hanger rod as
necessary.
When the correct pitch of the deck is acquired,
secure the inner hex nuts with a wrench and
tighten the outer hex nuts against the inner hex
nuts to lock them in the adjusted position.
