A riding lawn mower is a serious investment, but one that makes yard upkeep simple. Riding lawn mowers, or lawn tractors, are a little more complex than their push counterparts and require a lot more maintenance and upkeep to ensure they continue working for years. Keep a regular maintenance schedule, as well as tending to simple tasks every time you use your mower.
Change the oil after every 50 hours of use. The oil drain plug is somewhere near the bottom of the engine. Check your manual for specific draining instructions and the location of your drain.
Remove your oil filter, using an oil filter wrench by turning right. Change the oil filter when replacing the oil. Fill the engine with new oil once the oil filter has been replaced and tightened with the oil filter wrench.
Remove the cover over the air filter and check to see if it is dirty. If it is a paper filter, replace it if it looks dirty. Also replace the foam precleaner on the cover if it looks dirty. Replace the filter once a season.
Remove the sparkplug and replace once a season, using a ratchet to loosen the plug. Check the gap of the sparkplug, using a sparkplug feeler gauge, and make sure the gap matches the requirements of your engine, specified in your owner's manual.
Clean the mower, using a hose to remove loose grass.
Locate and clean the grease fitting on your tractor and use a grease gun to lubricate the fittings properly. Check in your owner's manual for the location of all your fittings.
