This cutting head holds the line that trims weeds and grass on several specific handheld gasoline trimmers. It is covered with a thick plastic cap that is bumped against the ground so that line can be released from the spool. The plastic bump head can endure an indefinite number of bumps against the ground. The cutting head not only experiences all the same bumps but also turns at 12,000 and must stop and start rapidly. As a result, after continual use, the cutting head sometimes requires replacement. There are several clues to suggest that a cutting head needs to be replaced. Most often, the bump function ceases to work or works sporadically. To replace the cutting head, press the slots in the bump housing to release the lower part of the housing. After removing the bump head, a ratchet is needed to remove the old head. Reverse the process to install the new cutting head. If a user must replace a cutting head, it is essential that it be replaced with a genuine OEM part made by Cub Cadet such as this one. This replacement cutting head is guaranteed to perfectly match the specifications of the original part it is replacing.

A bump head knob is a part of a string trimmer. When the trimmer is tapped against the ground or any hard surface, it will let out more line. This component, which is primarily made from rubber, is also responsible for securing the spool to the trimmer head. Over time, a bump knob can break. If it is damaged, the trimmer won't release more lines. It is easy to install a brand-new bump head knob replacement. First, get a screwdriver and unscrew the old bump knob. Grab the replacement and screw it to the trimmer head. Tighten it for a secure fit. This replacement only comes with a bump head knob. It doesn't have other string trimmer replacement parts.
