Deck Leveling Adjustment
WARNING: Protect your hands by wearing
heavy gloves to grasp the cutting blade.
NOTE: Check the tractor’s tire pressure before
performing any deck leveling adjustments. Refer to
Tires later in this section for further information
regarding tire pressure.
The front of the cutting deck is supported by two lift
links, one of which can be adjusted to level the deck
from both front to rear & side to side. The front of the
deck should be between 1/4-inch and 3/8-inch lower
than the rear of the deck. Adjust if necessary as follows:
With the tractor parked on a firm, level surface,
place the deck engagement/lift lever in the top
cutting height notch (not BLADES STOP) position.
Rotate the blade nearest the discharge chute so
that it is parallel with the tractor.
Measure the distance from the front of the blade tip
to the ground and the rear of the blade tip to the
ground. The first measurement taken should be
between 1/4" and 3/8" less than the second
measurement. Determine the approximate distance
necessary for proper adjustment and proceed, if
necessary, to the next step.
Place the deck engagement/lift lever in the
engaged (all the way forward) position.
Remove the hairpin clip from the ferrule found at
the bottom of the front, left deck link (hairpin clip is
on the inside of the lift link). See Figure 6.
Figure 6
Pull the ferrule out of the deck hanger and thread
the ferrule up or down, as necessary.
NOTE: Usually only one or two turns are needed.
Insert the ferrule back into the deck hanger and
refasten with the hairpin clip removed earlier.
Check the front-to-rear adjustment by re-
measuring. Check the side-to-side adjustment by
placing a level on the deck surface.
Readjust if necessary.
Deck Engagement Adjustment
WARNING: Never attempt to make the
adjustment while the engine is running.
Always shift to neutral, set the parking brake,
stop engine and remove key to prevent
unintended starting.
