The clutch assembly uses centrifugal force to connect the shafts and create the drive shaft motion that powers the machine. The drive shaft nests inside the other shaft, and over time these parts can wear and become damaged with regular use. Today's parts can even continue to function long past when they should, so it may not be apparent that a clutch assembly needs to be replaced until the entire unit is bad.

This is an MTD lawn mower clutch. The clutch is responsible for shifting up or down between speeds on the lawn mower. A lawn mower's brake/clutch pedal engages the clutch, which in turn allows the lawn mower to be placed in different speed settings, as well as forward and reverse. Typically all clutches end up going bad at some point due to general wear on the product. An overused clutch pedal can wear the part down and not fully engage the clutch before shifting gears. Once a clutch begins to wear down, there is a noticeable difference in the feel of the mower when shifting between gears. It may become difficult to move from one gear to the next. The easiest way to begin a clutch replacement is by putting the lawn mower onto a lifting mechanism or jacks at the underside. Remove the safety covers to allow access to the drive belt tensioner. Remove the belt from the pulley on the clutch. If the clutch is electric, the cable needs to be unplugged from the wire harness. Perform these steps in reverse to install the new component.This part is compatible with MTD and Cub Cadet machines. It is available individually as a genuine OEM product sourced from the manufacturer
