Secures the lower handle clip on line trimmers and lawn equipment. Replace if broken, stripped, or missing to properly mount the handle assembly.

This is the clutch drum that houses the clutch that engages the power tools on more than 50 gasoline-powered lawn and landscape devices. The clutch sits inside this housing, which enables it to rotate. When the RPMs of the engine reach a certain point, the clutch expands and causes the drive shaft of the tool to engage. Among the different kinds of equipment that use this clutch housing are cultivators, edgers, and grass trimmers. The clutch, and therefore the clutch drum, receive a great deal of wear for several reasons: the vibration of the engine, the rapid up and down change of engine revolutions, and resistance met by the tools that are transferred back to the clutch and housing. Signs that the clutch is failing include a slow response to increased engine RPMs and an inability for the power tool to engage the drive shaft. In these cases, the clutch and housing should be replaced in order for the equipment to operate properly again. When choosing a clutch housing, it is important to select one that, like this one, is a genuine OEM certified part. This housing is compatible with Craftsman, Troy-Bilt, MTD, Bolens, Yard-Man, and Ryobi equipment.

This replacement part is a rope guide, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. This rope guide allows the user to pull start the engine. The rope is connected to the transmission inside the engine that allows it to be turned off and on when desired. A new rope guide might be needed if the current one is damaged or missing. If the user is unable to start the lawn mower, then the rope guide might not be connected and should be replaced. Be sure that the engine is completely powered off while attempting this repair as this part is close to the engine inside the appliance. This part is sold individually and is a genuine OEM part sourced directly from the manufacturer to ensure proper fit in all appliances. Reference the owner's manual for more specific guidance.

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 simple set of lawnmower ignition keys. They’re also used for an array of riding mowers, lawn tractors, and even snowblowers. To simplify repair and replacement procedures, most manufacturers use standardized keys for all their machines in a given class. As a result, a single key can be used for dozens of machines. The keys are manufactured from stainless steel, with an INDAK logo stamped into the center. Regardless of whether the machine is a walk-behind mower or a full-sized lawn tractor, a keyed ignition is easier to operate than a recoil cord. Similarly, replacing a key is generally straightforward. The exception is if the old key has snapped off in the ignition. In this case, a set of needle-nosed pliers can sometimes be used to extract the key. A powerful magnet can also be helpful if the broken key is being stubborn. In the worst-case scenario, the ignition may need to be replaced. This is an OEM part sourced directly from MTD, and it is sold as a set of two.

This power cord extension is a genuine MTD part, sold individually. This power cord extension can be used as a replacement part for a snowblower. This power cord extension lengthens the reach of the power cord so that the appliance can be used from a greater distance from its direct power source while it is plugged in. The power cord extension might have to be replaced at some point if the cord suffers damage that renders it beyond functionality. This could occur if the cord is frayed, if it gets wet, or if it is punctured, torn, scratched, or eroded to the point that it does not power on the snowblower when properly plugged in. Remember to wear work gloves as a safety precaution while repairing or replacing parts within an outdoor appliance. This is an OEM part sourced directly from the manufacturer. It is sold individually. This power cord extension is compatible with the following outdoor appliance brands: MTD, Toro, Cub Cadet, Ryobi, Tecumseh, Lawn Boy, Huskee, Montgomery Wards, Bolens, Yard Man, Troy-Bilt, and Yard Machines.
