4. Setup and Installation

This kit is specifically designed for MTD Smart MiniRider 60 RD and 60 RDE models. Ensure your lawn tractor is compatible before proceeding.

4.1 Preparing Your Lawn Tractor

1. Park the lawn tractor on a flat, level surface.
2. Turn off the engine and remove the ignition key.
3. Disconnect the spark plug wire to prevent accidental starting.
4. Allow the engine and muffler to cool down completely.
5. Engage the parking brake.

4.2 Installing the Mulching Blades

If your existing blades are not mulching blades, or if they are worn, replace them with the mulching blades provided in the kit.

1. Carefully tilt the mower deck or lift the front of the tractor to access the underside of the deck. Use appropriate support stands for safety.
2. Using a wrench, remove the bolt holding the existing blade in place. Note the orientation of the blade for correct installation of the new one.
3. Remove the old blade.
4. Install the new mulching blade, ensuring the cutting edge faces the correct direction (usually indicated by an arrow or "grass side" marking).
5. Tighten the blade bolt securely to the manufacturer's specified torque. Refer to your lawn tractor's main manual for torque specifications.

4.3 Installing the Mulching Plug

The mulching plug is inserted into the discharge chute opening to seal it, allowing grass clippings to be recirculated under the deck for finer cutting.

1. Locate the discharge chute on the side of your mower deck.
2. Lift the discharge chute cover.
3. Insert the mulching plug firmly into the discharge opening. Ensure it fits snugly and creates a seal.
4. Lower the discharge chute cover over the mulching plug to secure it in place. Some models may have clips or pins to further secure the plug.

4.4 Installing the Side Discharge Deflector

The side discharge deflector is used when you want to discharge clippings out the side of the mower, typically for faster mowing without bagging or mulching.

1. If the mulching plug is installed, remove it first.
2. Position the side discharge deflector over the discharge opening.
3. Align the deflector's mounting points with the corresponding holes or pins on the mower deck.
4. Secure the deflector using the appropriate hardware (e.g., bolts, pins). Ensure it is firmly attached and pivots correctly if designed to do so.

5. Operating Instructions

5.1 Mulching Operation

Mulching returns finely cut grass clippings to the lawn, acting as a natural fertilizer. This is ideal for regular mowing of dry grass.

• Ensure the mulching plug is correctly installed (refer to Section 4.3).
• Remove the side discharge deflector if it is installed.
• For best mulching results, mow when the grass is dry and cut no more than one-third of the grass blade length at a time.
• Maintain a consistent, moderate speed. Mowing too fast can lead to clumping.

5.2 Side Discharge Operation

Side discharge is useful for cutting taller or damp grass, or when you prefer to leave clippings on the lawn without mulching them finely.

• Ensure the side discharge deflector is correctly installed (refer to Section 4.4).
• Remove the mulching plug if it is installed.
• Direct the discharge chute away from people, pets, and obstacles.
• Adjust your mowing pattern to distribute clippings evenly.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your mulching kit and deflector.

• Clean After Each Use: After each mowing session, clean grass clippings and debris from the mulching plug, deflector, and underside of the mower deck. This prevents buildup and maintains efficiency.
• Inspect Blades: Regularly inspect the mulching blades for sharpness, damage, or imbalance. Sharpen or replace blades as needed. Refer to your lawn tractor manual for blade sharpening guidelines.
• Check Fasteners: Periodically check all bolts and fasteners securing the mulching plug and deflector. Tighten any loose hardware.
• Storage: When not in use, store the components in a clean, dry place, protected from the elements.
