This is a genuine replacement for the line trimmer gearbox on select outdoor power trimmers. The gearbox is the housing that holds the gears responsible for turning the line reel. When the line reel turns, the string cuts grass and weeds. This part is made of durable metal, but it is also exposed to the elements and a lot of constant vibration, so it can become damaged over time and will need to be replaced. If the trimmer head stops spinning or there is a sudden grinding noise, it could indicate that this part needs replaced. It's important to use an OEM replacement for best results. This unit is sold as a complete assembly and includes the mounting hardware, three screws, head assembly, and the cap. A hex screwdriver, socket or wrench set, and Phillips screwdriver will be necessary to replace this part. Be sure to allow the unit to cool and wear gloves whenever performing repairs.This genuine OEM line trimmer gearbox is manufactured by MTD and compatible with machines from Craftsman.

This cutting head is designed for left-handed, gasoline-powered trimmers. The head contains eyelets for two sets of twine to effectively trim and edge. The assembly comes with a bump head knob so that twine can easily be increased. The knob and housing are made of extremely durable plastic that is at the same time responsive enough to respond to the user's call for additional twine. Typically, cutting assemblies work very well until a problem develops, at which time they stop working at all. Should it be necessary to replace a cutting head, the user should definitely make sure to use an OEM certified replacement. These are manufactured according to the same specification as the original. Users can replace the cutting hand by removing the cover of the trimmer's assembly. The old cutting head assembly should be able to be unscrewed. From this point, it is simply a reversal of the process, with the cover going over the new assembly and the assembly being reattached and covered. Several different manufacturers use this type of cutting head. Users will find it is compatible with MTD, Troy-Bilt, and Cub Cadet gasoline-powered trimmers.
