Check all fluid levels and top off as necessary before storage. Ensure that engine oil, hydraulic fluid, and fuel (if applicable) are at the recommended levels and free from contaminants. For gasoline engines, fill the fuel tank with a stable fuel conditioner to prevent phase separation and moisture build-up, and run the engine briefly to circulate the treated fuel through the system. If the fuel is to be left in the tank for an extended period, consider draining or stabilizing it according to the manufacturer’s recommendations to prevent gum deposition in the carburetor or fuel injectors. Inspect the air filter and replace it if it shows signs of aging or clogging, as a clean filter helps prevent moisture ingress and protects the engine upon startup after storage.

Seasonal storage should include a protective covering to shield the mower from dust, humidity, and accidental impact. Store the unit on a clean, dry surface with adequate ventilation to avoid moisture buildup underneath the deck. Elevate the machine slightly using stands or blocks to relieve weight from the tires and to promote air circulation, which helps prevent flat spots and corrosion on the rims. Lubricate accessible pivot points, linkages, and drive components with the manufacturer-approved lubricants, ensuring that any grease fittings are filled to the recommended specifications. Replace any worn or damaged guards or shields before storing to maintain safety and reduce the risk of damage from incidental contact during movement or maintenance.

Winterization procedures vary by climate and fuel type, but essential steps generally include securing the fuel system and protecting the cooling system. For two-stroke engines, ensure that fuel stabilizers are used and that the oil mixture remains correct to prevent lubrication issues upon restart. For four-stroke engines, remove or treat fuel as recommended by the engine manufacturer to minimize varnish formation and carburetor clogs. Drain and inspect the cooling system if the design allows, ensuring no air pockets remain in the coolant lines. After completing these steps, perform a final check of all fasteners, belts, and tires to make sure that nothing has loosened during operation or storage, and store the unit in a climate-controlled area to minimize condensation and corrosion risk. When returning the mower to service, carefully re-check fluid levels, reconnect the battery, and perform a short, controlled startup to verify proper operation before full use.
