Specs At A Glance

Good To Know

Q: Will this spindle assembly work with my existing blade? A: Yes, it uses the standard spindle shaft dimensions, so it accepts most OEM and aftermarket blades; however, confirm the blade center hole size matches your current setup.

Q: Do I need to replace both spindles at once? A: Not necessarily, but replacing worn spindles in pairs helps maintain even deck height and cutting performance.

Slight variation in finish or dimensions may occur between production runs, and confirm compatibility before ordering.
