What Is a Mower Deck Spindle and How Does It Work?
The mower deck spindle is a key component in the mower deck that helps to turn the blades and cut the grass. It is connected to the main drive shaft of the mower and is responsible for spinning the blades at the appropriate speed. The spindle is made up of several parts, including the spindle shaft, the spindle housing, the bearings, and the blades.
The spindle shaft is connected to the drive shaft and is responsible for turning the blades. The spindle housing is a metal casing that holds the bearings and blades in place. The bearings help to support the spindle shaft and keep it from vibrating. The blades are attached to the spindle shaft and are responsible for cutting the grass.
