Front To Back Leveling
The front to back pitch of the deck is normally
determined by the deck wheels when the deck is
operated as designed with its wheels on the
ground. However, the deck pitch should be checked
to ensure an even cut when mowing uneven terrain,
or when mowing with the deck wheels off the
ground.
When properly leveled, the pitch of the deck will
result in the front and rear cutting edges of the
blades being even, to a maximum of 1/4 inch lower
in the front.
The front to back pitch of the deck was initially set
when adjustment of the deck hanger rod assembly
was completed during deck installation and should
be within specifications. Check and, if necessary,
adjust the pitch of the deck as follows:
NOTE: Check for proper tire inflation before
checking and/or making a leveling adjustment.
• Use the tractor hydraulic lift system to raise the
deck so that its wheels are off the ground. Stop
the engine.
• Carefully rotate the outer cutting blades so that
the ends of the blades point to the front and
rear of the deck. See Figure 51.
NOTE: If side to side leveling of the deck was
correctly performed, measuring only the right
blade should be adequate to check the front to
back leveling.
Figure 51
• Accessing the right hand blade through the
discharge chute opening, measure the distance
from the front cutting edge to the ground
(measure A), and from the rear cutting edge to
the ground (measure B). The front edge of the
blade (measure A) should be between equal
with its back edge (measure B) and lower by a
maximum of 1/4 inch. See Figure 52.
Figure 52
• If the measurements are not within this range,
the front to back leveling of the deck should be
adjusted as follows:
• If the front of the deck is too low, the deck
hanger rod assembly must be shortened. From
the front of the tractor, evenly turn the hex lock
nuts clockwise to shorten the hanger rod
assembly and raise the front of the deck. See
Figure 53.
Figure 53
• If the front of the deck is too high, the deck
hanger rod assembly must be lengthened.
From the front of the tractor, evenly turn the
hex lock nuts counterclockwise to lengthen the
hanger rod assembly and lower the front of the
deck. See Figure 53.
NOTE: The front hanger rod must be against the
front of both slots in the deck front roller bracket. If
one side of the rod is not against the front of the
slot after attaining the correct front pitch to the
deck, tighten the front lock nut on that side until the
rod just contacts the front of the slot.
