6 Riding Mower Parts and Supplies to Keep on Hand

Blades. Cutting blades wear out fast when you mow the grass often. You never know when you’ll hit a rock or other foreign object and damage the blades.

Mandrels. Hitting rocks, stumps or other foreign objects can damage mandrels. You can avoid mower downtime by keeping an extra set of mandrels on hand.

Belts. Blade and ground drive belts can wear out quickly during the mowing season.

Mower-deck spray. Use this nonstick treatment that bonds to metal and plastic surfaces to keep grass clippings from sticking under the mower deck.

Fuel stabilizer. Keep your mower’s gasoline fresh to avoid engine-starting problems.

Tire sealant. Fixes flat tires and seals tire punctures up to ¼-inch in diameter.

Other nice-to-have parts and supplies—especially if you have a big lawn—include air filters, spark plugs, engine oil, oil filter, blade removal tool and flywheel keys.
