A dipstick is a part that is used to measure the amount of oil in various yard and garden equipment. It allows a person to reach an otherwise inaccessible space by inserting and then removing the dipstick. At that point, checking how much of the dipstick is covered in oil will let a person know whether it needs to be topped off. Over time, these tools can rust, break, or crack and will need to be replaced.Take a look at the dipstick for any damage before making a replacement of the part. If it needs to be replaced, it should be done while the lawnmower or other tool is cooled down. Unscrew the broken or damaged dipstick and take it out of the oil tank. Simply insert the new dipstick and screw it on before checking the oil level and using the machine again.This dipstick is a replacement part for Tecumseh, Cub Cadet, Toro, Briggs & Stratton, Troy-Bilt, Lawn-Boy, and Craftsman lawnmowers, wood chippers, and pressure washers. It comes as an individual component. It is a genuine OEM product that is sourced directly from the manufacturer.
