Good To Know

Q: Does this spindle come with the pulley and blade bolt? A: The spindle includes the shaft and bearing housing; pulleys, blade bolts, and mounting hardware are typically reused from your existing assembly or sold separately.

Q: How often should I replace mower deck spindles? A: Inspect spindles every season or when you notice excessive vibration or uneven cutting; replace if bearings feel rough or have play.
