I needed a replacement starter for my mower and wasn’t completely sure which one would fit. I sent them a message and they got back to me quickly, asked for my model information, and helped confirm the right part before I ordered. Everything was handled professionally and the communication was great. Very happy with the service.

Good To Know
Q: Does this switch include the key? A: This aftermarket switch is typically supplied with a new key that is cut to fit the included cylinder, so you do not reuse the old key.
Q: Is this the same as the OEM AR58126 part? A: This is a replacement part designed to meet or exceed the specifications of the original AR58126. It is not an original John Deere part but is intended to function as a direct substitute.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
