are even with each other when in the neutral position
Levelingthe 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 inch lower than the rear of deck
NOTE: Check the tractor's tire pressure before performing
any
deck leveling adjustments.
Seethe tire side wall for proper
inflation pressures.
Side to Side Leveling
If the cutting
deck appears to be mowing
unevenly, a side
to side adjustment
can be performed
Adjust if necessary
as follows:
•
With the tractor parked on a firm, level surface,
place the deck lift handle in the top notch (highest
position) and rotate both outer blades so that they are
perpendicular
to the tractor frame
•
Lower the deck to the middle
height position
•
Measure the distance from the outside left blade tip
to the ground and the distance from the outside right
blade tip to the ground
The measurements
should be
equal
If they're not, proceed to the next step
•
Comparing
the two measurements,
determine
whether
the left side of the deck must be raised or lowered
•
Loosen, but do not remove, the hex cap screw on the
left deck hanger bracket
See Figure 6-6
Gear
Figure 6-6
•
Level the deck by using a wrench to turn the
adjustment
gear (found immediately
behind the hex
cap screw just loosened)
clockwise to raise the left side
of the deck, or counterclockwise
to lower the left side
of the deck See Figure 6-6
•
The deck is properly
leveled when left and right blade
tip measurements
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
1/4 inch
lower than the rear of the deck. Adjust if necessary 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 approximately
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 hex nuts
on the deck front hanger rod and turn them away from
the inner nuts Refer to Figure 6-7
•
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
Refer to Figure 6-7

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 rodjust 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.
