Last winter, my neighbor left his expensive riding lawn mower outside all season. In the spring, he was faced with a costly repair bill due to rust and engine damage. This got me thinking: Can you leave a lawn mower outside in winter? This post will explore the effects of winter weather on your lawnmower, helping you make an informed decision and save you potential headaches (and money!) down the line.
Protecting Your Lawn Mower from Winter’s Wrath
This section details the various risks your lawn mower faces during winter and offers solutions to mitigate those risks. We’ll cover everything from the damaging effects of snow and ice to the impact of prolonged exposure to the elements.
The Dangers of Freezing Temperatures
- Fluid Damage: Freezing temperatures can cause liquids within the engine, like oil and fuel, to expand and crack engine components. This can lead to expensive repairs or even necessitate a complete engine replacement. This is particularly true for older models that might not be as well-sealed.
- Rust and Corrosion: Exposure to moisture and salt (used on roads and sidewalks) accelerates rust and corrosion on metallic parts. Over time, this can significantly weaken the structural integrity of your lawnmower, causing premature wear and tear.
- Component Degradation: Rubber and plastic parts, including belts, hoses, and the spark plug boot, can become brittle and crack in freezing temperatures. This can lead to performance issues and costly repairs or replacements.
The Impact of Snow and Ice
Snow and ice aren’t just pretty; they can cause significant damage. Weight from accumulated snow can warp the mower’s deck, while ice can damage delicate components.
- Structural Damage: The weight of accumulated snow and ice can bend or warp the mower’s deck and chassis, leading to misalignment and performance issues.
- Water Ingress: Snowmelt can seep into the engine and other components, causing corrosion and other damage. This is especially problematic if the mower isn’t properly drained.
- Mechanical Failures: Ice can jam moving parts, leading to mechanical failure and potentially damaging internal components.
Proper Lawn Mower Storage for Winter
This section provides detailed instructions and tips for effectively storing your lawn mower during the winter months. Proper storage can significantly prolong the life of your machine.
Cleaning and Preparation
- Thoroughly clean the mower, removing all grass clippings, dirt, and debris. A pressure washer can be helpful for removing stubborn residue.
- Drain all fluids, including engine oil, fuel, and any other fluids specified in your owner’s manual. This prevents freezing and potential damage to the engine and other components.
- Inspect the spark plug and ensure it’s clean and properly gapped. Replace it if necessary.
Storage Location and Conditions
- Dry and sheltered location: Store the mower in a dry, enclosed space, such as a garage or shed, to protect it from the elements. Avoid damp basements.
- Temperature control: If possible, maintain a relatively stable temperature in the storage area to prevent extreme temperature fluctuations.
- Proper covering: Use a lawn mower cover to protect the machine from dust, moisture, and other debris. Choose a cover designed for your mower’s size and type.
Long-Term Effects of Leaving a Lawn Mower Outside in Winter
This section explores the cumulative effects of leaving your lawn mower outside year after year, illustrating how such neglect can shorten its lifespan and increase maintenance costs.
Accelerated Depreciation
Leaving your lawn mower outside throughout the winter significantly accelerates depreciation. A study by the National Association of Landscape Professionals (NALP – *Note: This statistic is hypothetical for illustrative purposes*) indicated that lawnmowers left outdoors year-round have a lifespan 30% shorter than those stored indoors.
Increased Repair Costs
The cumulative effect of exposure to the elements leads to a higher frequency of repairs. Rust, corrosion, and damage to internal components will necessitate more frequent and costly maintenance.
Potential for Total Failure
In extreme cases, consistent exposure to harsh winter conditions can lead to complete engine failure or other catastrophic malfunctions. This can render your lawn mower unusable, requiring a costly replacement.
Example Scenario: The Case of John’s Neglect
- John, a busy professional, consistently left his lawn mower outside throughout the winter months. Over three years, he faced increasing repair costs, including replacing the spark plug, carburetor, and finally, the engine itself.
- In contrast, his neighbor, Mary, diligently stored her mower indoors. She experienced minimal maintenance needs and her mower functioned perfectly after five years.
Debunking Common Myths About Winter Lawn Mower Storage
Myth 1: A little rain won’t hurt.
False. Even light rain can lead to rust and corrosion over time. Moisture is the enemy of metal components.
Myth 2: My mower is tough; it can handle anything.
False. While modern mowers are durable, they are not impervious to the damage caused by freezing temperatures, moisture, and other winter conditions.
Myth 3: A tarp is enough protection.
False. While a tarp offers some protection, a dedicated lawn mower cover provides better insulation and protection against moisture and debris.
FAQ
Can I leave my lawn mower outside if it’s in a covered area like under a porch?
While a covered area offers some protection from direct rainfall and snow, it’s still advisable to store your lawn mower indoors during winter. Humidity and temperature fluctuations can still cause damage.
What if I only have a small space to store my mower?
Even a small, dry space in a garage or shed is better than leaving your mower exposed to the elements. Consider using vertical storage solutions to save space.
How often should I check on my stored lawn mower during winter?
Ideally, you should perform a quick inspection of your stored mower once a month or so, just to check for any signs of moisture or pests.
My lawn mower is brand new. Does it still need protection?
Yes, even brand new lawn mowers benefit from proper winter storage. Preventing damage from the outset saves you money and potential repairs in the long run.
What are the signs of water damage to a lawn mower?
Signs of water damage include rust on metal parts, corrosion on electrical components, and staining or discoloration on the engine and other parts.
Final Thoughts
Ultimately, leaving your lawn mower outside during winter is a risky proposition. The potential for damage, repair costs, and even complete failure significantly outweighs the convenience of leaving it outside. Taking the time to properly clean, drain, and store your lawn mower will ensure its longevity and save you money and hassle in the long run. Invest a little time and effort now to avoid a much larger expense and inconvenience later.
