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 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 to thenextstep.
• Comparing the two measurements, determine
whether t he rightsideof thedeckmustberaised
or lowered.

Levelthe deck by usinga wrenchto turn the
adjustment gear (foundimmediately b ehindthe
hexcap screwjust loosened) clockwise to lower
the rightsideof the deck,or counterclockwise to
raisetherightsideofthedeck.SeeFigure 37.

If the sideto side levelingwas donecorrectly,
measuringjust the right blade should be

• Measure the distancefromthe front tip of the
bladeto the groundandthe distancefromthe

measurements taken earlier are equal.
• Retighten the hex cap screw on the right deck

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:
Figure 38
• 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 38.
• 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.
