Riding Mower Maintenance

Regular riding mower maintenance helps keep your machine ready for everything from the front yard to the grass around the barn. Start with the owner’s manual for your model’s service schedule, recommended engine oil and replacement part specifications, then keep track of operating hours so routine mower service doesn’t slip by during mowing season. Before each mow, check the engine oil as directed, inspect for leaks, clear loose debris from engine cooling screens and check tire pressure with the tires cold. Even tire pressure helps the mower deck sit level for a more consistent cut. Before cleaning, inspecting or servicing your riding lawn mower, park on level ground, disengage the blades, set the parking brake, shut off the engine and remove the key. Let moving parts stop and hot components cool, and disconnect the spark plug wires before working near the blades or beneath the deck. Follow the manual’s battery-disconnection instructions for the task, too. Change the mower oil and oil filter at the recommended intervals, and inspect or replace the air filter as directed, checking it more often in dusty conditions. Keeping the mower deck, blades and drive system in shape is another big part of riding lawn mower maintenance. Clear away grass buildup after mowing once the machine is safely shut down and cool, following the manufacturer’s cleaning directions rather than spraying water around electrical components or bearings. Inspect mower blades for nicks, bending and excessive wear; sharp, balanced blades cut grass cleanly instead of tearing it. Replace damaged blades, and follow the specified blade-bolt torque during installation. If access requires lifting the mower, follow the manufacturer’s lifting procedure and support it properly—never rely on a jack alone. Check belts for cracks or fraying, inspect pulleys and guards, and lubricate grease fittings at the intervals listed in the manual. Battery terminals should stay clean and connections snug, while spark plugs and fuel filters need attention on the recommended schedule. Before putting your riding mower away for the off-season, clean it thoroughly, handle remaining fuel according to the engine manufacturer’s storage directions and follow the battery storage instructions. A little attention throughout the season can help prevent breakdowns right in the middle of a busy mowing day.
