the lift rod threads to lower the left side of the
mower deck.

Recheck the measurements described in step 4. If
the blade measurements are not within 1/16 inch,
repeat steps 4 and 6 until the correct measure-
ment is obtained.

B. FRONT TO BACK LEVELING

The front lift rod must be correctly adjusted to maintain
the proper pitch of the deck when mowing uneven terrain.

Adjust the front caster wheel arms and rear deck
rollers to their highest setting (lowest deck setting).

Position the mower blades so the ends of each
blade point to the front and the rear of the tractor
(See Figure 21).

Figure 21

Refer to Figure 22. Measure and record the dis-
tance from the front cutting edge to the ground
(measure A), and from the rear cutting edge to the
ground (measure B), for both outer blades. The
front edge of each blade (measure A) should be
lower than its back edge (measure B) by approxi-
mately 1/8 inch.

Figure 22

Adjust the front lift rod as follows to attain the
proper pitch of the mower deck (See Figure 23).

• Loosen the hex jam nuts and lock washers on the

front lift rod.

• From the front of the tractor, turn the front hex lock

nuts clockwise to raise the front of the deck, or
counterclockwise to lower the front of the deck.

• Recheck the measurements described in step 3

and readjust the hex lock nuts until the proper
measurements are obtained.

NOTE: The front lift rod should be fully to the front of
both slots in the deck front roller bracket. If one side of

the rod does not contact the front of the slot, tighten the
corresponding lock nut as needed.

Figure 23

Tighten the rear jam nuts and lock washers
against the backside of the front lift bracket after
adjustment of the rod has been completed.

C. SETTING THE CUTTING HEIGHT

NOTE

Cutting height adjustment should be performed only
AFTER the mower deck has been properly leveled.

If the mower deck is installed on a tractor without the
deck downstop feature, the cutting height is set by
positioning the front caster wheel arms in one of five
settings in the height adjustment bracket of the deck.

If the deck is installed on a tractor with the downstop
feature,

the

cutting height is set by using either the

deck height adjustment knob to set the deck downstop
position or by positioning the caster wheels in one of
five settings.

USING THE CASTER WHEELS AND ROLLERS TO
SET CUTTING HEIGHT

WARNING

Before adjusting the caster wheel/roller posi-
tions, place the PTO switch in the “OFF” posi-
tion, engage the parking brake lever, and turn
the ignition key to the “OFF” position.

NOTE

Note the index holes of the height adjustment
bracket are not sequential (top to bottom) in
relation to their corresponding height setting,
and the lower hole in the caster arm is used for
settings 2 and 4 (See Figure 24).

Use the tractor lift system to raise the mower deck
off the ground.
