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 replacement bell washer, a flat washer that can be used with a wide range of various types of lawn and garden equipment. The inner dimension of this washer is 0.40 inches, while the outer dimension is 0.88 inches. Washers are typically used as a way to help ensure a tight connection when used with bolts or screws. They will also help to distribute the pressure of the connection and reduce the risk of corrosion. Washers will also provide some protection from damage during installation. Washers could need to be replaced for any number of reasons. In some cases, they might have become corroded or worn down over time. This could mean they no longer provide a solid and secure connection. Other times, the washer could become lost while working on the machine. Owners should always be sure that they replace any lost or damaged washers right away. Not using washers can reduce the lifespan of the machine. This is a genuine OEM bell washer that is sold individually. It is typically used in lawn mowers, snowblowers, tillers, leaf blowers, string trimmers, log splitters, wood chippers, edgers, and chainsaws. It is compatible with Craftsman, Cub Cadet, Ryobi, Troy-Bilt, Husky, Murray, Yard Machines, MTD, Huskee, Montgomery Wards, Bolens, Yard-Man, Turf King, and MasterCut brands.

This is a two in one blade that can be used as a lift blade to bag clippings, as well as a side discharge for clippings. It is time to consider replacing this blade when there are uneven or even missed areas of cutting or bagging when using the mower. It may be that the blade has been dulled by prolonged use or bent or damaged by striking rocks and dense roots. Either way, replacing the blade is a relatively easy repair to make and should be considered a part of routine maintenance. The repair requires the use of the proper tools, including wrenches and sockets. An appropriate flange bolt may need to be purchased as well if the original has been damaged or worn. "This OEM replacement cutting blade works with more than 150 types of tractors and mowers made by Craftsman, Yard Machines, Yard-Man, MTD, and Troy Bilt. This ships singly and is a high-quality blade made of durable materials.
