the PTO belt, and remove belt from the PTO pulley.
4. Pull down on the lift hooks (A, Figure 4) and unhook
the lift chains (B).
5. Turn the wheels straight ahead. Pull back on spring-
loaded lever (B, Figure 5) and lift mower hitch off of

Installing the Mower Deck
NOTE: Perform mower installation on a hard, level sur-
face such as a concrete floor.
1. Park the tractor, fully lower the attachment lift, turn off
the PTO switch, turn off the engine, remove the key,
and engage the parking brake. Turn the wheels fully
to the left.
2. Place mower in the lowest cutting position using the
mower height adjuster. Slide the mower deck under
the right side of tractor so that the mower hitch is
aligned with front tractor hitch (A, Figure 5).
3. See Figure 5. Turn wheels straight. Pull back on the
spring-loaded lever (B) while lifting up on the mower
hitch. Install the mower hitch onto tractor hitch brack-
ets (A). When properly installed, the spring-loaded
lever should seat fully underneath the brackets (A).
4. See Figure 4. Connect the mower lift chains (B) to
the the tractor lift hooks (A).
NOTE 50” & 54” Mowers: The two-link lift chain is bolted
to the mower deck using the second link. This is correct
for most mowing applications.
5. See Figure 4. From left side of tractor, use the idler
arm (D) to relieve belt tension. Install belt (C) onto the
PTO pulley.

Installation Instructions Roller Bar Mower Kit
LevelingThe Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci-
fied in Checking Tire Pressure.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Place the mower in mid-cut position. Arrange the out-
side mower blades so that they are pointing from
side-to-side.
4. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8”
(3mm) difference between the measurements on
each side, proceed to step 5. If the difference is 1/8”
(3mm) or less, proceed to step 6.
ECCENTRIC NUT MODELS
5. See Figure 8. Loosen the outside nut (A). Turn the
eccentric nut (B) to raise or lower left-hand side of
mower. When mower is level, hold the eccentric nut
while tightening the outside nut.
NOTE: 44”, 50”, & 54” Mowers. When using a turbo col-
lection system, raise the discharge side of the mower
approximately 1/4” (6mm) to compensate for turbo
assembly weight. Check the level of the cut grass and
adjust the 1/4” (6mm) measurement as necessary for a
smooth, even cut.
FRONT-TO-BACK LEVELING
NOTE: 54” mowers have two adjustment rods that
should be adjusted simultaneously.
6. Arrange the blades so they face front-to-back.
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades.
Front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand
blades. If not, proceed with steps 8 - 9.
8. To raise front of mower deck, loosen front nut (B) and
turn rear nut (A, Figure 10) against bracket. To lower
front of mower deck, loosen rear nut (A) and the
bracket will move backwards to lengthen rod.
