1 Removing the Original Hardware No Parts Required

Procedure 1. Ensure that all moving parts have stopped, the parking

brake is engaged, and the key has been removed. 2. Raise the front of the machine and support it with jack

stands.

WARNING Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction, allowing the unit to fall, which could cause injury.

Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

Important: The right-hand blade on this mower deck is counter-rotating and uses a left-hand threaded blade bolt.

3. Remove the blades and retain them for removal of the baffle kit.

4. If the mower has been used, scrape the underside of the mower deck clean.

5. Remove the hardware that plugs the exposed mounting holes in the deck.

For 60-inch decks, remove the 6 hex-socket screws (5/16-18 x 3/4 inch) and flanged nyloc nuts plugging the exposed mounting holes in the deck (Figure 1).

Note: Retain these parts for future use.

Figure 1 60-inch deck shown

1. Parts that need to be retained

For 72-inch decks, remove the 4 hex-socket screws (5/16-18 x 3/4 inch), the flanged nuts plugging the exposed mounting holes in the deck, and the inboard-tire-flap fastener on each side (Figure 2).

Note: Retain these parts for future use.

1. Install the front outer baffles by using one carriage bolt (3/8-16 x 7/8 inch) and one flange nut (3/8-16) per baffle (Figure 3).

Note: To help align the baffles, loosely insert the carriage bolts (3/8-16 x 2.5 inches) and flange nuts (3/8-16) through the side of the baffles and the bumper (Figure 6).

2. Install the front center baffle with 3 carriage bolts (3/8-16 x 7/8 inch) and flange nuts (3/8-16) as shown in Figure 3.

3. Install the rear outer baffles by using one carriage bolt (3/8-16 x 7/8 inch) and one flange nut (3/8-16) per baffle as shown in Figure 3.

Note: To help align the baffles, loosely insert the carriage bolts (3/8-16 x 2.5 inches) and flange nuts (3/8-16) through the side of the baffles and the bumper (Figure 6).

Note: The front outer baffles install between the rear-baffle tabs.

Note: The 72-inch model uses one carriage bolt (5/16-18 x 1 inch) and one flange nut (5/16-18) in the rear of the right-hand baffle, the left-hand baffle, and

the innermost square hole on the inboard tire flap on each side (Figure 3).

4. Install the rear center baffle using 2 carriage bolts (3/8-16 x 7/8 inch) and 2 locknuts (3/8-16) as shown in Figure 4.

Note: This baffle installs between the front outer baffle flanges (Figure 4).

Note: Where the front outer baffles, the rear outer baffles, and the rear center baffle come together, install 2 carriage bolts (3/8-16 x 7/8 inch) and the 2 locknuts (3/8-16) as shown in Figure 4.

4 Installing the Blades

Parts needed for this procedure: 1 20.5-inch rotary blade (red)60-inch model only

2 20.5-inch low-flow blade (black)60-inch model only

1 24.5-inch rotary blade (red)72-inch model only

Procedure Note: Determine the left and right sides of the machine from the normal operating position.

Important: The right-hand blade on this mower deck is counter-rotating and uses a left-hand threaded blade bolt.

1. Install the red reverse-rotation blade onto the right-hand spindle (Figure 7).

Note: Ensure that the curved part of the blade is pointing upward toward the inside of the mower deck to ensure proper cutting.

Note: Ensure that the curved-washer cone is installed towards the bolt head (Figure 8).

2. Install the 2 black blades onto the center and left-hand spindle (Figure 7).

3. Torque the blade bolts to 115 to 150 N-m (85 to 110 ft-lb).

Note: Carefully and slowly rotate each blade 360 by hand to ensure that there is clearance between the blades and the baffles. Adjust the baffles slightly if interference is found.

WARNING Incorrect installation of the blades or components used to retain the blades can be dangerous. Failure to use all of the original components and ensuring that everything is assembled as shown could allow a blade or a blade component to be thrown out from under the deck, resulting in serious personal injury or death.

Always install the blades and the blade-retaining hardware; refer to the Operators Manual.

4. Carefully remove the jack stands and lower the machine to the ground.
