Typically, your lawn mower’s deck is designed with a side chute that discharges grass clippings back out onto the lawn or into a bagger. A mulch kit changes this process by changing the standard mower blades to operate as a mulcher. Mulch blades chop grass clippings into smaller pieces than the standard blades. The smaller pieces decompose faster and help return nutrients back into the soil, keeping your grass healthy. Mulch kits generally include mulching blades and a mulching plug, along with necessary hardware for installation.
Before performing any maintenance on your tractor, refer to your operator’s manual for recommended maintenance, safety information, and instructions for your machine. Mulch kits and mulch kit installations will vary with tractor models, so depending on your tractor model number our instructions may vary slightly.
Before performing any repair or maintenance on your mower, please follow these safety precautions:
- Read your owner’s manual for all safety and installation instructions
- Park your tractor on a hard, flat surface
- Shut off the engine and allow it to cool
- Set the parking brake
- Remove the key from the ignition to prevent accidental starting
To carry out this task, you’ll need:
- Mulch kit
- Block of wood
- Piece of cardboard
- Heavy duty gloves (cutting blades are sharp – always wear gloves when working with blades)
Use a Jungle Jack or other form of jack to lift the front of your mower to create space under the mower deck. Use your wrench to remove the center nut from the mower blade. Use a gloved hand to keep the blade from turning while removing the nut. Keep the blade nuts for the installation of the new blades. Remove the nut and mower blade on the other side of the deck.
Remove the cutting deck from beneath the tractor as instructed in your owner’s manual. Put down a piece of cardboard to protect the deck and flip the deck over on top of the cardboard to access the underside.Place a block of wood between the deck housing baffle and the blade to keep the blade in place while removing the nut. Use your wrench to remove the nut that secures the mower blades. Keep the blade nuts for the installation of the new blades. Remove the nut and mower blade on the other side of the deck.
Now that the old blades have been removed, it’s time to replace them with the new blades included in the mulch kit. Install the blades with the side marked “bottom” or with the part number on it facing the ground when the tractor is in the operating position. Place the center hole of the blade over the mounting stud on the underside of the mower deck. Use your gloved hand to hold the blade in place while tightening the blade nut with your wrench. Install the blade on the other side of the deck as well.
If you removed the mower deck to replace the blades, flip the deck back to the upright position to install the mulch plug.
To install the mulch plug on your tractor, lift the discharge chute up. Insert the mulch plug into the deck discharge chute opening by putting the bolt on the rear side of the mulch plug into the hole in the deck. Twist the mulch plug into place. Pull and stretch the retaining plug on the mulch plug over the deck wheel bracket and hook it under the bottom of the bracket.
If you removed the mower deck to replace the blades, slide the deck back under the tractor and reattach the deck as instructed in your owner’s manual. If you raised the mower deck to replace the blades, use the jack to lower the deck.
