Carton Contents

Before beginning installation, remove all parts from the carton to make sure everything is present. Carton contents are listed below and shown in Figure 1-1. Part numbers are listed in parentheses.

• Two Mulching Blades (742-0616A)
• One Deck Mulch Plug Assembly (631-05195A)

Blade Installation

1. Remove the cutting deck from beneath the tractor as instructed in your tractor's Operator's Manual.
2. Gently flip the deck over to expose its underside.
3. Stabilize one of the cutting blades with a blade lock tool or a block of wood. See Figure 1-2.
   Figure 1-2: Diagram illustrating how to stabilize a cutting blade with a block of wood and showing the location of the hex flange nut.
4. Remove the hex flange nut that secures the blade to the spindle.

   IMPORTANT: The hex flange nuts have a right-handed (normal) thread pattern. Do NOT attempt to force the nuts in the opposite direction. Doing so may damage the nuts.

5. Repeat steps 3 and 4 on the other cutting blade.
6. Replace the blades with the blades included in the kit. Be sure to install each blade with the side marked "Bottom" (or with a part number stamped in it) facing the ground when the mower is in the operating position.

   IMPORTANT: Use a torque wrench to tighten each blade spindle's hex flange nut to between 90 ft-lb and 110 ft-lb.

Installing the Mulch Plug

1. Pivot the chute deflector upward and remove the protective cover from the pin found on the deck's surface. See Figure 1-3.
   Figure 1-3: Diagram showing the chute deflector being pivoted upward to reveal a pin on the deck's surface.
2. To install the mulch plug, pivot the discharge chute upward. Refer to Figure 1-4:
   Figure 1-4: Diagram illustrating the installation of the mulch plug, showing two connection points: (a) inserting the mulch plug rod into a bracket, and (b) positioning the rear of the mulch plug over a pin on the deck.
   • a. Insert the mulch plug rod into the hole found on the bracket (or deck wheel bracket, on models so equipped).
   • b. Position the rear of the mulch plug over the pin found on the deck's surface.
3. Slide the mulch plug wire (747-06686) over the pin on the deck's surface, position the washer over the wire, and secure the mulch plug with the wing knob. See Figure 1-6.

   Figure 1-6: Diagram detailing how to secure the mulch plug using the wire, washer, and wing knob. An inset highlights the wire positioned correctly inside the deck lip.

   NOTE: Make sure that the wing knob is snug, and the wire is positioned inside the lip of the deck to keep the mulch plug securely in place. See the inset in Figure 1-6.
