Winter is a tough time for machines, and your lawn tractor needs extra care before hibernation. A few quick maintenance steps can protect it from corrosion, battery failure, and fuel damage, saving you time and money when spring returns.
Start by treating your engine. Moisture inside can cause internal rust during long storage. “Fogging” the engine prevents this by coating the cylinders with a thin oil mist. Just remove the spark plugs, spray fogging oil into each cylinder, and reinstall the plugs. This step forms a protective layer that guards against corrosion.
Next, ensure your battery is fully charged. Cold temperatures can damage uncharged batteries. Use a charger to bring it to a healthy 12.7 volts before storage. A well-maintained battery ensures your tractor will start easily when the weather warms up.
Don’t forget your fuel system. Gasoline can deteriorate and clog fuel lines over time. Add a stabilizer to the tank before winter.
If you are uncertain whether your gas contains ethanol—which can limit stabilizer effectiveness—run the engine dry (run it until it runs out of gas).
Lastly, protect your tractor from pests. Cover the air intake and exhaust openings with plastic wrap or aluminum foil to prevent rodents from nesting inside.
These three simple steps will help your lawn tractor stay in prime condition through the winter and ready for another productive season.
