Winter Storage For Your Rotary Mower

Is Your Rotary Mower Ready for Winter?

Did you know that over 30% of lawnmower problems reported in the spring are directly linked to improper winter storage? Many homeowners mistakenly believe that simply parking their mower in the garage is sufficient. This oversight can lead to costly repairs and a frustrating start to the mowing season. Protecting your investment requires a little more care than just finding a dry spot for it.

Why Bother with Proper Winter Storage?

Proper winterization safeguards your rotary mower from several common threats that can shorten its lifespan and degrade its performance. Cold temperatures, moisture, and pests can wreak havoc on essential components if left unprotected. For instance, untreated fuel can degrade, leading to a gummed-up carburetor that makes starting your mower a nightmare come spring. Additionally, moisture can cause rust on metal parts and damage the engine block.

What Happens If I Don’t Winterize?

Imagine this: you pull your mower out of storage in April, eager to tackle your overgrown lawn. You pull the starter cord, but nothing happens. You check the fuel, and it looks cloudy. After a trip to the repair shop, you’re told the carburetor is clogged and the spark plug is corroded. This scenario, unfortunately, is all too common. Neglecting winter storage can result in a non-starting mower, damaged engine parts, and a significantly reduced resale value.

How to Prepare Your Mower for Storage

The first crucial step is to clean your mower thoroughly. Remove all grass clippings, dirt, and debris from the deck, engine, and wheels. A clean mower prevents moisture from being trapped and reduces the risk of rust. Think of it like giving your mower a spa treatment before its long nap. A clean machine is less likely to harbor mold or attract unwanted critters.

Fuel System Care: A Critical Step

Next, address the fuel system. The easiest method is to run the mower until it nearly runs out of gas. This minimizes the amount of fuel left in the tank and carburetor. Alternatively, and often recommended, is to add a fuel stabilizer to the tank. Fill the tank about halfway with fresh gasoline, add the stabilizer according to the product’s instructions, and then run the engine for about five to ten minutes. This ensures the treated fuel circulates throughout the entire fuel system, preventing oxidation and varnish buildup.

Snippet: Preparing your rotary mower for winter involves cleaning it thoroughly and addressing the fuel system. Add a fuel stabilizer or run the tank nearly dry to prevent fuel degradation. This simple process significantly reduces the risk of spring starting problems and costly repairs.

Engine Oil and Spark Plug Maintenance

Changing the engine oil before storage is another vital task. Old oil contains contaminants and acids that can damage internal engine components over time. Draining the old oil and refilling with fresh oil ensures your engine is protected. While the oil is draining, it’s also a good time to remove and inspect the spark plug. Clean it or replace it if it looks worn or fouled. Some recommend squirting a small amount of clean engine oil into the cylinder through the spark plug hole, then slowly pulling the starter cord a few times to distribute the oil. This lubricates the cylinder walls and piston rings, offering further protection against corrosion.

Battery and Blade Considerations

If your mower has an electric start, remember to disconnect the battery. Store it in a cool, dry place, ideally on a shelf off the concrete floor, as concrete can draw out its charge. Consider using a trickle charger to maintain its charge throughout the winter. For the mower’s blade, it’s wise to remove it, clean it, and sharpen it. Applying a light coat of oil or grease to the blade before storing it will prevent rust. A sharp blade also means less strain on the engine when you resume mowing.

The Often-Overlooked: Storage Location & Cover

Where you store your mower is as important as how you prepare it. Choose a dry, sheltered location, such as a garage, shed, or covered patio. Avoid storing it directly on a concrete floor if possible; placing it on a piece of wood or an old mat can help prevent moisture absorption. Using a breathable mower cover is also highly recommended. This protects it from dust, dirt, and accidental scratches while allowing any residual moisture to escape, preventing condensation buildup.

An Overlooked Detail: Tire Pressure

Many people forget about the tires. Over the winter, the weight of the mower can cause flat spots to develop on the tires, especially if they are underinflated. Slightly overinflating the tires before storage can help prevent this. If you’re storing the mower for an extended period, consider placing blocks under the deck to take the weight off the wheels entirely. This simple step ensures your tires will be in good condition when you need them next season.

Final Checks and Secure Storage

Before you close the door on your winterized mower, give it one last look-over. Ensure all parts are secure and that no loose wires or components are exposed. If you have a riding mower, it’s wise to engage the parking brake. For walk-behind models, ensure the handle is in a stable position. Now, your mower is ready to brave the winter months confidently. Will you take these steps to ensure your mower starts strong next spring?
