Choosing and Using a Lawn Mower Cover for Protection

Protecting your lawn mower from the elements is a simple, cost-effective way to extend its life and maintain its performance. A good cover shields the engine, deck, and controls from rain, sun, dust, and debris. The key is knowing how to choose a lawn mower cover that offers real protection and how to use it properly. In this guide, we’ll walk through the materials, fit, and features that matter, and the right steps to cover and uncover your machine.

Why Use a Lawn Mower Cover?

A cover is your mower’s first line of defense when it’s not in use. Leaving a mower exposed, especially outdoors, can lead to a host of preventable problems. Moisture is the primary enemy, promoting rust on the deck and undercarriage, corroding electrical connections, and potentially contaminating fuel. Prolonged sun exposure can fade paint, crack plastic components, and degrade rubber belts and tires. A cover also keeps out leaves, pollen, dirt, and nesting pests, which can clog cooling fins, air filters, and moving parts. Using a cover is a basic part of seasonal lawn mower maintenance and helps preserve your investment.

How to Choose a Lawn Mower Cover: Materials and Construction

The material of your cover determines its durability, water resistance, and breathability. Here are the common types:

• Polyester or Polyethylene: These are often lightweight, affordable, and provide good water resistance. Many are treated with a UV coating to help block sun damage. They are a popular choice for general protection.
• Vinyl or Tarpaulin (Tarp): These materials are heavier and offer excellent waterproofing. They are very durable against abrasion but can be less breathable, which might trap moisture underneath if the mower is covered while damp.
• Fabric Blends (with waterproof laminate): Some covers use a multi-layer approach, like a soft inner fabric with an outer waterproof laminate. This can offer a balance of protection, durability, and scratch resistance for painted surfaces.

Regardless of material, look for double-stitched or reinforced seams, which are less likely to tear. A soft, non-abrasive inner lining is a bonus feature that helps protect your mower’s finish.

Finding the Right Fit and Key Features

A cover that fits well stays on in the wind and provides complete coverage. A baggy cover can flap and chafe, while one that’s too small will leave parts exposed.

Proper Covering Technique

Putting a cover on correctly is just as important as having one. Follow these steps to ensure you’re protecting, not harming, your mower.

1. Let the Mower Cool Completely: Never cover a hot mower. The trapped heat can damage components and is a fire hazard. Wait until the engine and exhaust are cool to the touch.
2. Clean the Mower: Brush off clippings, mud, and debris from the deck and wheels. This prevents moisture from being trapped against the metal and keeps the inside of your cover clean. For a thorough clean, see our guide on maintaining your grass catcher and deck.
3. Ensure It’s Dry: If the mower is wet from rain or dew, let it air dry before covering it. Covering a damp mower guarantees moisture will be sealed in, accelerating rust.
4. Position the Cover: Drape the cover evenly over the mower, aligning any access panels or vents. Ensure the entire machine, including the seat on a rider, is covered.
5. Secure the Cover: Use the elastic hem, drawstring, or tie-down straps to snug the bottom around the mower’s base. In windy areas, use additional rope through the grommets to anchor the cover to the mower or a stationary object.

What a Cover Protects Against

A well-chosen and properly used cover addresses several common sources of wear and damage:

Remember, a cover is part of a larger protection strategy. For long-term seasonal storage, additional steps like fuel stabilization are necessary. A cover also complements other essential lawn mower accessories that improve your mowing experience.

FAQ

Can I use a generic tarp from the hardware store?

You can, but it may not be ideal. Generic tarps are often very heavy, not breathable, and can have rough seams that scratch your mower. They are also difficult to secure snugly, often flapping loudly in the wind. A purpose-built mower cover is usually a better fit and offers features like vents and soft linings.

Should I cover my mower after every use?

If your mower is stored in a dry, enclosed garage or shed, covering it after every use may not be critical. However, if it’s stored on a porch, under a carport, or outdoors, covering it consistently is highly recommended to protect it from dust, humidity, and accidental moisture.

My cover got wet. What should I do?

If the outside of the cover gets wet from rain, it’s doing its job. Just ensure it’s still securely tied down. If the cover gets soaked through or the *inside* gets wet, remove it as soon as possible and allow both the mower and the cover to dry completely before re-covering.

Does a riding mower cover need different features?

Yes, riding mower covers are larger and should account for the steering wheel, seat, and higher profile. Look for a cover specifically sized for riding mowers, with extra length to cover the front grille and rear tires. Strong tie-downs are especially important due to the larger surface area that can catch wind. Proper care also extends to other parts, like the wheels and tires.

Can I leave the cover on while the mower is in a shed?

It’s generally safe and can provide extra protection against dust and pests. However, ensure the shed is dry and the mower was completely cool and dry before being covered. In a damp shed, a non-breathable cover might trap ambient moisture against the metal.
