A clean lawn mower deck is a happy lawn mower deck! But seriously, removing grass buildup from your mower isn't just about aesthetics. It can actually improve your mower's performance, extend its life, and even help your lawn look better.

 

Why is Grass Buildup a Problem?

 

 

 

 

Think of grass buildup like cholesterol for your mower. It may seem harmless initially, but over time, it can cause a host of problems:

• Suffocating Your Lawn: Caked-on grass restricts airflow under the deck, hindering the mower's ability to create suction. This leads to uneven cutting, scalping (cutting the grass too short), and an overall unhealthy lawn.

• The Rust Monster: Damp grass clippings become a breeding ground for rust and corrosion, eating away at your mower's metal components and shortening its lifespan.

• Clogzilla: Buildup can clog the discharge chute, causing frustrating clumps and uneven dispersal of clippings.

• Blade Blunting: Grass buildup makes it difficult to sharpen your blades effectively, resulting in a dull cut that tears grass instead of slicing it cleanly. This stresses the grass, making it more susceptible to disease.

 

 

How to Remove Grass Buildup

 

 

 

Before you begin, safety first! Disconnect the spark plug wire to prevent accidental starts. Wear gloves to protect your hands.

1. Gather Your Tools

Protective Gloves: Shield your hands from sharp blades and debris.
Safety Glasses: Protect your eyes from flying debris.
Putty Knife or Scraper: Your weapon of choice against caked-on grass.
Wire Brush: For tackling stubborn, stuck-on grime.
Garden Hose with Spray Nozzle (or Pressure Washer): The rinsing power you need.
WD-40 or Similar Lubricant: A post-cleaning treat for your mower.



2. Tilt the Mower

Tilt the mower on its side, ensuring the air filter and carburetor are facing upwards. If you have a mower lift or ramps, use them to make this easier and safer. 


3. Scrape Away the Gunk

Use a putty knife or scraper to remove large clumps of grass. A wire brush can help loosen stubborn buildup.



4. Wash It Down

Use a garden hose with a spray nozzle or a pressure washer to rinse away any remaining debris. Be careful not to spray water directly into the engine or air filter.

5. Dry Thoroughly

Wipe down the deck with a towel and allow it to air dry completely.

6. Prevent Future Buildup

Clean after each use: A quick scrape and rinse after each mowing session can prevent major buildup.
Use a mower deck spray: These sprays create a non-stick surface that helps prevent grass from sticking.

 

Sharpen your blades regularly: Sharp blades cut cleaner, reducing the amount of grass that gets stuck to the deck.

 

Advanced Cleaning Tactics

• Baking Soda Power: For tough stains, create a paste of baking soda and water. Apply, let it sit, then scrub and rinse.

• Vinegar's Versatility: Vinegar is a natural cleaning agent that dissolves grass stains and helps prevent rust.

• Degreaser Duty: Heavy buildup may require a commercial degreaser for a truly deep clean.

Beyond the Deck: Mastering Grass Clippings

Cleaning your mower deck is only half the battle. Here's how to handle those grass clippings like a pro:



Grasscycling: The Eco-Friendly Choice

Leave those clippings right where they are! Grasscycling is a fantastic way to return valuable nutrients to your lawn. As the clippings decompose, they act as a natural fertilizer, reducing the need for chemical alternatives.



Mulching Mastery

If you have a mulching mower, it finely chops clippings, making them perfect for grasscycling. This speeds up decomposition and minimizes the risk of thatch buildup.



Other Clippings Strategies

• Raking: For a tidy look, rake clippings into a pile for easy disposal or composting.
• Blowing: A leaf blower can quickly relocate clippings to a desired location or disperse them for faster decomposition.
• Composting: Grass clippings are a valuable addition to your compost pile, contributing to nutrient-rich compost for your garden.
• Lawn Sweeper: These efficient tools gather clippings and other debris, making cleanup a breeze.

Cleaning your mower deck isn't just about aesthetics; it's an investment in the longevity of your machine. By preventing buildup and corrosion, you'll enjoy years of reliable service from your trusty lawn mower. So, grab your tools, conquer those clippings, and enjoy a healthy, happy lawn!
