Adjustments
Note: Disengage PTO, shut off engine, wait for
all moving parts to stop, engage parking brake, and
remove key before servicing, cleaning, or making any
adjustments to the machine.
Deck Leveling
Note: Small adjustments can be accomplished by
increasing the tire pressure in the tire on the low side.
1.
Adjust the height — to increase, turn the
adjuster screw clockwise; to decrease, turn
counterclockwise.
2.
Loosen the jam nuts on the top of each deck
adjuster. Fine tune the adjuster on the front deck
lift assembly by turning it to get the correct height
for the center deck left and right front blade tips
3.
Measure the back tip height. Fine tune rear
adjusters as required
4.
Re-measure until all four sides are the correct
height. Tighten all the jam nuts on the deck lift
arm assemblies

inflation pressure for tires is 13 psi (90 kPa).
Adjust if necessary
8.
Push the button down on top of the lever to
disengage the deck lift latch. Pull the handle all
the way rearward and release the button to latch
the cutting deck into the raised transport position.
9.
Insert the height adjustment pin into the 3 inch
(7.6 cm) cutting height location.
10.
Slightly pull the handle rearward and push the
button down on top of the lever to disengage the
transport lock. Allow the handle to move forward
to lower the cutting deck to the cutting height.
11.
Raise the discharge deflector.
12.
Carefully rotate the blades front to rear. Measure
from the level surface to the front tip of the
center blade. The measurement should read 3
inches (7.6 cm).
Note: In most conditions, the back tips on the
side blades should be adjusted 1/8-1/4 inch
(3.2-6.4 mm) higher than the front.
