Key, Ratchet

This is a ratchet key for a lawnmower. This part is a genuinely sourced part and is sold individually. The ratchet key is found in the rear wheel to hold the pinion gear securely on the shaft of the adjusting arm. A small spring provides tension on the key and should be inspected at the same time (spring sold separately). Often a sign that the key is worn or damaged is if it is no longer engaging the gear. For this repair you may require a 12mm socket and snap-ring pliers.
