Poulan Pro Mulch Kit with Blades

1. Product Overview

The Poulan Pro Mulch Kit is designed to convert compatible lawn tractors to mulching units. This kit is specifically engineered for tractors manufactured from 1992 onwards that feature 38-inch vented decks. The primary function of this kit is to finely cut grass clippings and return them to the lawn as natural fertilizer, eliminating the need for bagging.

The kit includes a mulch plate, a set of mulching blades, and the necessary mounting hardware for installation.

2. Safety Information

WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

Always prioritize safety when working with lawn equipment. Failure to follow safety instructions can result in serious injury or death.

• Read Your Tractor Manual: Before installing or operating this mulch kit, thoroughly read and understand the safety and operating instructions provided in your lawn tractor's owner's manual.
• Disconnect Power: Always disconnect the spark plug wire(s) or remove the ignition key before performing any maintenance, installation, or adjustments to the mower deck or blades.
• Wear Personal Protective Equipment (PPE): Always wear safety glasses, gloves, and sturdy footwear when handling blades or working on the mower deck.
• Blade Handling: Mulching blades are sharp. Handle them with extreme care to prevent cuts.
• Secure Equipment: Ensure the tractor is on a flat, stable surface and the parking brake is engaged before beginning any work.
• Keep Clear: Keep hands, feet, and clothing away from moving parts, especially the mower blades, during operation.

3. Package Contents

Verify that all components are present in the package:

• 1 x Mulch Plate (also referred to as a mulch plug or deflector block)
• 1 x Set of Mulching Blades (typically two blades for a 38-inch deck)
• Mounting Hardware (may include pins, clips, or other fasteners)

This image displays the main components of the Poulan Pro Mulch Kit: a black plastic mulch plug designed to block the discharge chute, and a sharp metal mulching blade. These parts work together to finely cut grass clippings.

4. Installation Instructions

Follow these steps to install the mulch kit:

1. Prepare the Tractor: Park the tractor on a level surface, engage the parking brake, and turn off the engine. Disconnect the spark plug wire(s) to prevent accidental starting.
2. Access the Mower Deck: Depending on your tractor model, you may need to lower the mower deck to its lowest position or remove it entirely for easier access. Refer to your tractor's manual for specific instructions on deck removal if necessary.
3. Install the Mulch Plate: The mulch plate is designed to fit into the discharge chute opening of your mower deck. Position the mulch plate so it securely blocks the opening. It typically snaps into place or is secured with pins/clips. Ensure it is firmly seated to prevent grass from escaping.
4. Replace Blades (if necessary): If your tractor does not already have mulching blades, or if your current blades are worn, replace them with the new mulching blades provided in the kit. Use a blade removal tool or a block of wood to hold the blade steady while loosening the blade nut. Install the new blades with the cutting edge facing the correct direction (usually indicated by an arrow or text on the blade). Tighten the blade nut to the torque specification found in your tractor's manual.
5. Verify Fitment: After installation, visually inspect the mulch plate and blades to ensure they are correctly installed and do not interfere with any other components. Some users have reported fitment issues with the plastic deflector on certain 38-inch decks, particularly non-Poulan Pro models. If the mulch plate does not fit securely or appears to be obstructed, consult your tractor's manual or contact customer support.
6. Reconnect Power: Once installation is complete and verified, reconnect the spark plug wire(s).

5. Operating Instructions

To achieve optimal mulching performance:

• Mow Dry Grass: For best results, mow when the grass is dry. Wet grass tends to clump and does not mulch as effectively.
• Maintain Appropriate Speed: Operate the tractor at a slower speed than you might for bagging or side-discharge. This allows the blades more time to cut and recut the grass clippings into finer particles.
• Avoid Overloading: Do not attempt to mulch excessively tall or thick grass in a single pass. If the grass is very long, raise the cutting height for the first pass, then lower it for a second pass to achieve a finer mulch.
• Multiple Passes for Heavy Debris: When mulching heavy leaf fall or very dense grass, it may be necessary to make two or three passes over the area to ensure all material is finely processed and distributed.
• Blade Engagement: Ensure the mower blades are fully engaged and spinning at maximum RPM for effective mulching.

6. Maintenance

Regular maintenance ensures the longevity and performance of your mulch kit:

• Clean the Deck: After each use, clean the underside of the mower deck and the mulch plate to remove accumulated grass clippings. Buildup can reduce mulching efficiency and lead to corrosion.
• Inspect Blades: Regularly inspect the mulching blades for sharpness, bends, or damage. Dull blades tear grass instead of cutting it cleanly, leading to an unhealthy lawn and poor mulching.
• Sharpen or Replace Blades: Sharpen blades as needed, or replace them if they are bent, cracked, or excessively worn. Always replace both blades as a set to maintain balance.
• Check Mounting Hardware: Periodically check all mounting hardware for the mulch plate and blades to ensure they are tight and secure.

7. Troubleshooting

• Poor Mulching Performance / Clumping:
  • Grass may be too wet or too tall. Mow when dry and consider multiple passes.
  • Blades may be dull or damaged. Sharpen or replace blades.
  • Mower speed may be too fast. Reduce ground speed.
  • Excessive grass buildup under the deck or on the mulch plate. Clean thoroughly.
• Mulch Plate Does Not Fit:
  • Verify your tractor model and deck size (38-inch vented deck, 1992 and later). This kit is designed for Poulan Pro models, and fitment on other brands or specific non-Pro Poulan models may vary.
  • Ensure the mulch plate is oriented correctly.
• Damage to Mulch Plate During Operation:
  • The plastic mulch plate is designed to be durable but can be damaged by impact with hard objects or if it comes into contact with spinning blades due to improper installation or extreme conditions. Always operate with caution and avoid obstacles.
