MowerPartsGroup Mower Deck Spindle Assembly

This assembly is designed for 48-inch mower decks and is compatible with several major brands, including Craftsman, Husqvarna, Ariens, and Poulan.

Because this assembly includes a grease fitting, you should lubricate it periodically to maintain smooth operation. A good rule of thumb is to add grease every 25 to 50 hours of operation, or at the start and end of each mowing season.

You likely need a new spindle if you notice excessive vibration while mowing, hear a grinding or squealing noise from the deck, or see visible wobble in the blade. If the blade doesn't spin freely by hand when the mower is off, the bearings inside the spindle have likely failed.
