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.

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model

Select 50-inch and 54-inch mower decks specifying spindle family 618-04125 / 918-04126.

Check deck model, shaft length, mounting pattern, pulley type and included hardware. Do not assume all 50- and 54-inch decks use the same spindle.

Product Overview

When this type of part wears out or stops doing its job, the symptoms can be easy to mistake for a larger equipment problem. This three-piece spindle set replaces damaged blade-support bearings and housings on compatible Cub Cadet, MTD and Troy-Bilt decks.

Key Features & Performance

Three mower deck spindle assemblies. Designed for the listed application, with the goal of repairing or servicing the existing equipment rather than replacing an entire machine.
