Replace your tiller's worn, cracked, or broken wheel assembly. This replacement wheel mounts to the axle and enables smooth maneuvering of your tiller.

This is a small engine spark plug positioned in the engine cylinder head. It supplies the spark that will ignite the air-fuel mixture to enable an engine to produce power. This particular spark plug is designed with superior corrosion resistance and dependable performance. Small but mighty, this component allows for increased conductivity and heat control. If the spark plug is damaged or in poor condition, many problems may arise in equipment, including sudden stop while running, overheating, and excessive gas consumption. Replace the spark plug by disconnecting the spark plug wire first, then use a socket driver or wrench to remove the spark plug. Install the new spark plug by turning it by hand initially to avoid cross-threading. If it doesn't twist anymore, use a deep socket wrench or socket driver to tighten the plug until snug. The spark plug can also be used to tune up outdoor power equipment or improve a small engine. This part is recommended to be replaced once per season. This part works with lawn mowers, snowblowers, tillers, leaf blowers, log splitters, wood chippers, and others with small engines. It is compatible with brands such as Craftsman, Cub Cadet, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Bolens, Yard-Man, and MasterCut. This is a genuine OEM part directly from the manufacturer and is sold individually.
