Most common Sears parts that need replacing on Craftsman riding lawn mowers and lawn tractors
- Air filter. The air filter prevents abrasive particles from entering the engine's cylinders, which could cause mechanical wear and oil contamination.
- Alternator. The alternator is a set of wire coils under the flywheel of the engine that generates electricity to power the tractor when it's running. The alternator also recharges the battery while the engine runs.
- Flywheel key. The flywheel key is a small metal rectangle that keeps the crankshaft and flywheel aligned when you tighten the flywheel nut. To protect more expensive components from damage, the flywheel key is designed to shear if the mower blade hits an object hard enough to make the flywheel slip out of alignment with the crankshaft.
- Blade belt. The blade belt attaches to the engine pulley and spins the cutting blade(s). Use our Sears PartsDirect Craftsman mower parts lookup to find the belt you need for your model.
- Spark plug. The spark plug is the device responsible for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine. This current ignites the compressed fuel/air mixture by means of an electric spark, while containing combustion pressure within the engine.

How to fix the mower deck when it vibrates on your Craftsman riding mower or garden tractor
- If the mower vibrates when you engage the cutting blades, there might be a problem with the blade drive system.
- Deck vibration can be caused by an unbalanced blade, worn pulley or mandrel, bad blade belt or debris caught inside a pulley.
- Loose nuts or bolts on the pulleys, mandrels or blades can also cause vibration. Remove the mower deck and re-tighten all fasteners.
- Check for wear on pulleys, mandrels and blades. Replace any worn or damaged components.
