John Deere Spindle Assembly AUC15811 for 42 and 48 Inch Decks

The John Deere spindle assembly AUC15811 is a genuine OEM replacement spindle designed for John Deere mower decks measuring 42 inch and 48 inch. Built with heavy-duty housings and precision bearings, this spindle is engineered to deliver smooth blade operation and consistent cutting performance year after year.

John Deere spindles are designed for long-lasting durability and reliable operation under demanding mowing conditions. Using genuine OEM replacement spindles helps maintain proper deck performance, reduce vibration, and extend the life of your mower.

Important Installation Note

The mounting holes used to secure the spindle to the deck are not pre-threaded. The supplied or existing mounting hardware is self-threading and will form threads in the housing material as the bolts are tightened. This is normal and part of the design.
