This grease fitting attaches to the cast pivot bar on many types of garden and lawn equipment. It is made of durable metal and ensures that internal parts of the equipment are lubricated so they operate at their full potential. Sometimes a grease fitting can become worn damaged and need to be replaced.If a lawn tool no longer seems to be properly lubricated, the grease fitting could be the cause. A pair of pliers will be required to make the replacement. Clean the area near the grease fitting and then use a hex wrench to remove it from the machine. Take the new fitting and place it into the hole and tighten it before applying grease.This is a genuine OEM replacement grease fitting that is sourced directly from the manufacturer.
