Storing a lawn mower improperly over the winter is a common mistake that drastically shortens its lifespan. While many homeowners lack ideal storage solutions like sheds or garages, leaving equipment exposed to the elements poses significant risks. This guide explains why outdoor storage is suboptimal and how to mitigate those risks if you have no other choice.
Why Outdoor Storage Is Problematic
The biggest threat to lawn mowers during winter is moisture. Cold temperatures make plastics brittle, causing cracks. Rust and corrosion attack metal parts, while electrical components suffer short circuits from water damage. Even sunshine contributes, as UV rays degrade plastic and rubber. Rodents also seek shelter in engines, gnawing on vital wiring. These issues aren’t merely theoretical; they lead to costly repairs or premature replacements.
The severity of these problems depends on the mower type:
- Electric mowers (corded or battery-powered) are the most vulnerable. Water seepage can destroy electrical systems, making outdoor storage almost guaranteed failure.
- Gas mowers fare slightly better but still suffer from rust and corrosion over time.
- Riding mowers are more durable but seats deteriorate from prolonged exposure.
- Reel mowers, being simpler, are less susceptible, but metal parts remain vulnerable to rust.
How to Protect Your Mower Outdoors
If you must store your mower outside, take these steps to minimize damage:
- Elevate the unit: Place it on a pallet or similar structure to promote air circulation and reduce moisture contact.
- Cover it securely: Use a durable tarp and check it regularly for tears or dislodgement from wind.
- Consider a lean-to: A basic, makeshift shelter provides additional protection against rain and snow.
The Most Overlooked Step: Undercarriage Cleaning
One of the most frequent mistakes is failing to clean grass clippings from the mower deck’s underside. These clippings trap moisture, accelerating rust. Scrape them off after every use with a putty knife. Neglecting this simple step can destroy the mower’s structural integrity.
Proper winterization extends the life of your equipment, saving money in the long run. Taking the time to prep your mower, even for outdoor storage, is a small investment that pays off in fewer repairs and replacements.
