How to Install a Mulch Kit on Your Riding Mower

Mulching is one of the best ways to maintain a healthier, greener lawn. A mulch kit allows your riding mower to chop grass into fine clippings that decompose quickly and return nutrients back into the soil. Installing one is easier than many people think—just follow this step-by-step guide.

🌱 What Is a Mulch Kit and Why Use It?

A mulch kit typically includes:

• Mulching blades (designed to cut grass multiple times)

• Deck plug or cover (blocks the chute to keep clippings under the deck)

• Mounting hardware

Benefits of mulching:
✅ Improves soil health
✅ Reduces yard waste
✅ No need for raking or bagging
✅ Helps retain lawn moisture
✅ Gives a cleaner, more polished lawn look

🧰 Tools You’ll Need

Before starting, prepare:

• Wrench or socket set

• Screwdriver

• Gloves for protection

• Mower lift or jack (optional but helpful)

• Safety glasses

• 
  

⚙️ Step-by-Step Installation Guide

1. Turn Off and Prepare the Mower

• Park on a flat surface

• Turn off the engine and remove the key

• Disconnect the spark plug for safety

2. Raise the Mower Deck

This gives you enough space to work underneath.

• Use your mower’s deck lift lever

• Or use a mower jack for easier access

3. Remove the Old Blades

• Use a wrench to loosen the blade bolts

• Keep track of bolts and washers

• Remove the blades carefully (they may still be sharp)

4. Install the Mulching Blades

• Place the new mulching blades in the same position as the old ones

• Tighten securely using the bolts
  ✔ Make sure the blade edges face the correct direction

5. Attach the Mulch Plug / Blocker

• Locate the mowing deck's discharge chute

• Install the mulch plug to block grass from exiting

• Secure it with bolts or clips (depending on your model)

This step is key because it forces grass to circulate and get cut into smaller pieces.

6. Double-Check Everything

Make sure:

• Blades are tight

• Plug is secure

• No loose hardware remains under the deck

7. Reconnect and Test

• Reconnect the spark plug

• Start the mower

• Perform a quick test on a small patch of grass

You should notice:
✅ No grass discharging from the chute
✅ Fine clippings on the lawn
✅ Smoother, cleaner cutting result

🧩 Useful Tips After Installation

• Mow regularly so grass doesn't get too tall

• Avoid mulching wet grass (it clumps and clogs the deck)

• Keep the deck clean to improve airflow

• Sharpen mulching blades every 20–25 hours of use

•
