This is a throttle trigger assembly for a string trimmer. This part is used to engage the throttle cable, which opens the carburetor to add more of a mix of fuel and air into the combustion chamber. A new throttle trigger assembly will be needed if it is damaged in a way that prevents it from operating correctly. It could be broken by physical impact or could wear out with normal extended use. If the throttle trigger is not effectively actuating the throttle cable, it will need to be replaced. Allow the trimmer plenty of time to cool down before attempting to perform any care or maintenance on the machine.This throttle trigger is made to be used with string trimmers. It's an OEM part sourced directly from the manufacturer and it is sold individually. This part is used on MTD, Craftsman, Yard Machines, McCulloch, Remington, White Outdoor, and Troy-Bilt brands.

This is a genuine replacement screw designed for use in select MTD engines on lawn and garden equipment. Specifically, this is an anti-rotation screw, which is used to stop the drive shaft housing from turning inside of the main housing assembly. This screw is a small part that is subject to constant vibrations, pressure, and high temperatures. It can sometimes become worn or damaged as a result or even break off entirely, which would mean that the inner housing would no longer be held in place accordingly. If this screw is damaged or lost, it needs to be replaced with a genuine OEM replacement as soon as possible. This MTD anti-rotation screw is manufactured with high-quality materials and designed for use in select trimmers from MTD, RYOBI, Yard-Man, Troy-Bilt, Murray, Cub Cadet, Yard Machines, and Bolens. This replacement will require a screwdriver. Simply remove the damaged screw, if it is not already missing, from the clutch cover assembly, and then install the new screw. It should only take a few minutes to perform the replacement. Be sure to wear gloves to protect the hands. This screw is sold individually and does not include any additional parts or hardware.

This is a blade lock nut that is typically a component of string trimmers and edgers. The blade lock nut ensures the cutting blade is securely attached to the shaft of the trimmer. If the nut is corroded, broken, or has come loose, it will need to be replaced. The equipment should not be operated without this nut since other components could come loose and fall off.This is a simple part to replace and will require only a wrench or a socket set. This nut is located on the spindle, so a visual inspection can be done to ensure it is damaged or broken. Remove it and thread the new blade lock nut to the same location. If the nut is stripped, a bolt remover can be used to get it off of the lawn equipment.This blade lock nut is sold as an individual part. It is an authentic OEM replacement part that is sourced directly from the manufacturer. The part is made to fit a variety of edgers and string trimmers manufactured by Craftsman, Cub Cadet, MTD, Ryobi, and Yard Machines.
