Cotter pins are simple but very effective fasteners used primarily to hold wheels in place on mowers. This is particularly true of the front wheels on riding mowers. Cotter pins are very light and can become overly pliable after extensive use. In some cases, the front wheels of a mower, which are the guide wheels that steer the device, become difficult to manage. The cure for this situation is often simply the replacement of the cotter pins that are not holding the guide wheels adequately in place. Before attempting to remove the pins, it is essential that the spark plug boot is moved so that the mower cannot be started. This is an important safety step because the repairer will be getting under the mower near the blades. The back wheels should be blocked so the mower cannot move, then the front end placed up on blocks. Remove the mower's hubcaps to gain access to the axle spindles. Straighten the legs of the pin so that when the curved portion of the cotter pin is grasped with pliers and it can be pulled straight back and be removed. The spindle, washers, and wheels should be checked for wear before the new pin is placed and secured. This OEM cotter pin is compatible with Bolens, Yard-Man, Craftsman, Yard Machines, Cub Cadet, Turf King, Troy-Bilt, Huskee, Toro, Ryobi, MTD, MasterCut, Murray, and Montgomery Wards.

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.
