Mower Removal and Installation

NOTE: Perform mower deck installation and removal
on a hard flat surface such as a concrete floor.

Removal

Releasing the Mower Deck Belt Tension

1. Disengage the PTO, engage the parking brake,

turn off the ignition, remove the key, and wait for
all moving parts to stop.

2. Remove the cutting height pin and lower the

attachment lift to its lowest position.

3. Release the belt tension and remove the belt.

44” & 50” Mower Decks:

Pull the lever (A, Figure

9) towards the rear of the machine to release
tension on the mower belt. Secure the lever in the
guard notch (B) and remove the mower belt from
the PTO pulley (C, Figure 10).

46” Mower Decks:

Pull the lever (A, Figure 9)

towards the rear of the machine to release the
tension on the mower belt. Remove the mower
belt from the PTO pulley (C, Figure 10).

54” Mower Decks:

a. Using a 1/2” breaker bar, place the square end in

the square hole located in the idler arm (A, Figure
11). Carefully rotate the breaker bar COUNTER-
CLOCKWISE, which will relieve the tension on the
belt exerted from the idler arm. Slide the belt off of
the stationary idler pulley (B).

b. Carefully release the tension on the breaker bar.

c. Remove the belt from the PTO pulley (C, Figure

10).

Removing the Mower Deck from the Unit

1. Pull the hair pins (C & D, Figure 12) and

disconnect the deck leveling links (I & J).

2.

44” & 50” Simplicity Models Only:

Pull the hair

pin and disconnect the roller bar connecting rod
(M).

WARNING

Use extreme caution when rotating the idler
arm with the breaker bar, due to increased
tension in the spring as the idler arm is being
rotated. Injury may result if the breaker bar is
prematurely released while the spring is under
tension.

4. Lift the front of the deck using a 2 x 4 as a lever,

pull the handle (G) forward to release the front
hangers rod ends (H), then push rearward to
release the rear rod ends.

5. Pivot the front wheels out of the way and slide the

mower deck out from under right side of the unit.
