Installing the Mower Deck

NOTE: Perform mower installation on a hard, level surface 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 brackets (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.

Leveling The 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 specified 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 outside 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 collection 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.
