The lock nut is a piece of standard hardware that may have a variety of applications on lawn and garden equipment, including on engines, housings, and other components. The lock nut offers a secure fit by tightening into a flange that prevents the nut from loosening like a regular nut might. Over time, the flange or the nut can become worn or damaged. In some cases, lock nuts may be lost during the process of other repairs or maintenance. Replacing them with genuine OEM parts like this lock nut is the best solution. This lock nut is compatible with hundreds of machines, including mowers, snowblowers, and chippers from MTD, Troy-Bilt, Cub Cadet, RYOBI, Yard-Man, Yard Machines, Bolens, and Husky. The ¼-inch lock nut has multiple locations and applications, so owners should consult their parts diagram for exact placement and part number identification. This lock nut is made of durable metal and sold as a single unit. Those who need additional pieces will have to order multiple quantities. This part will require a wrench or a socket to replace, as well as pliers and/or a screwdriver to hold the bolt or screw in place.

This is a bushing made from black plastic with a cleft down the middle to provide enough flex for easy insertion. It has a flanged design, which means it won’t easily pop out after installation, even under stress from constant vibration. The bushing’s primary purpose is to protect wires and cables from damage as they pass through a channel. As such, the material is fairly durable and does not need to be replaced under ordinary circumstances. That said, there are some situations in which it can become damaged. For one thing, it’s easy to damage while repairing the wires or cables that run through the bushing. If the bushing does need to be replaced, it requires disconnecting any cables or wires that run through the bushing. Pop out the old bushing with a rubber mallet, install the new bushing the same way, reconnect the wires, and the repair is complete. This is an OEM part sourced directly from MTD, and it is sold individually. It was initially used on snowblowers but has also been used on lawnmowers and lawn tractors.
