This Stens Spindle Pulley helps smooth the rotation of blades to ensure a clean, consistent cut of lawns. Spindle pulleys are an important component in a mowers cutting deck along with the spindle itself. Manufactured to original specifications, this spindle pulley runs flat and true, providing smooth motion for the spindle assembly. Stens spindle pulleys are solidly built to resist breaking, bending and warping that can lead to inconsistent blade movement. Stens spindle pulleys can help restore a mowers ability to produce an even and uniform cut of turfgrasses preferred by lawn cate professionals. A new spindle pulley will also eliminate squealing, buzzing and vibration that can occur from a worn or defective pulley. Stens spindle pulleys can keep mowers working at peak performance to maintain beautifully manicured lawns.
