This is a simple set of lawnmower ignition keys. They’re also used for an array of riding mowers, lawn tractors, and even snowblowers. To simplify repair and replacement procedures, most manufacturers use standardized keys for all their machines in a given class. As a result, a single key can be used for dozens of machines. The keys are manufactured from stainless steel, with an INDAK logo stamped into the center. Regardless of whether the machine is a walk-behind mower or a full-sized lawn tractor, a keyed ignition is easier to operate than a recoil cord. Similarly, replacing a key is generally straightforward. The exception is if the old key has snapped off in the ignition. In this case, a set of needle-nosed pliers can sometimes be used to extract the key. A powerful magnet can also be helpful if the broken key is being stubborn. In the worst-case scenario, the ignition may need to be replaced. This is an OEM part sourced directly from MTD, and it is sold as a set of two.

This washer is compatible with most lawn mowers and lawn tractors. The smooth, round edges fit perfectly with 5/8-inch bolts to attach the bolts to parts on the mower, as necessary. The washer provides a buffer between the bolt and the surface that it is being attached to. They are highly recommended for protecting parts that are being fastened together.The lack of a washer can cause permanent damage to the piece that the bolt is attached to. If the bolt does not have a washer to prevent it from moving and rusting, it can cause the bolt to fail. With products such as lawn mowers, this can spell disaster for both the appliance and its handler. These washers are high-quality and will prevent excess corrosion for the bolt. However, moisture and residue left after use can cause the washers to fail. In this case, a replacement will be necessary. This replacement part is compatible with most lawn mowers and tractors.
