This replacement part is a center sprocket. This is a genuine replacement part made by MTD. This part is used to connect certain pieces and use a turning or rotating mechanism to allow the engine to run properly and effectively. A new center sprocket might be needed if the current one has worn ridges. This can be due to a high level of friction after years of normal wear and tear. Because of the rotating motion, this part can be easily stripped over time and will need to be replaced. Wear work gloves during this repair to prevent injury to the user and those around them.

This kit includes a replacement debris shield designed to mount beneath the mower deck around the blade area.

An idler pulley is an essential part of many small and medium sized gasoline powered tools. This idler pulley is used in equipment such as tillers, lawn tractors, log splitters, edgers, snow blowers, and trimmers. The idler pulley is necessary so that the engine can run without the tool's moving parts being engaged. For instance, a lawn tractor running without the cutting blades turning or the wheels rolling. Once the idler pulley is engaged, the blade begins to turn. There is a great deal of resistance encountered by the idler pulley each time the equipment's tools begin to turn. Over time, the pulley can become worn and will eventually need to be replaced. If there is a squealing sound whenever the moving parts of a lawn tool are engaged, it is probably a sign that the idler pulley is about to fail. The pulley itself is attached to the engine housing with 9/16 hex bolts and requires an adjustable wrench and 9/16 ratchet to remove and replace. Always use a genuine OEM manufactured replacement part such as this one when replacing the original, as this part is identical to the original. This part is compatible with equipment manufactured by Bolens, MTD, Cub Cadet, Huskee, and Troy Bilt.
