Specs At A Glance

Good To Know

Q: How often should these deck spindles be greased? A: Most sealed-bearing spindles are maintenance-free, but check your mower's manual; if greasable fittings are present, add grease every 25 hours of operation.

Q: Can one spindle be replaced, or should all three be changed together? A: While a single faulty spindle can be swapped, replacing all three at once ensures even wear and balanced blade performance across the entire deck.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
