Combining innovative design with exceptional durability, the Stens Xtreme PTO Clutch keeps your mower working longer and delivering better lawn care results. The Electric Xtreme PTO Clutch's Cool Coil technology with a proprietary composite coil runs approximately 20% cooler than many electromagnetic clutches. Heat reduction extends clutch service life. Machined billet pulleys allow for smoother and faster blade speeds, resulting in lawns that looks more even and cleanly cut. High performance bearings with a proprietary high temperature grease extends anticipated working life. Tripled layered, integrated watertight connectors protect the wiring system from moisture, rocks, sticks, stumps, curbs and other objects that can cause damage. Stainless steel rivets improve the overall strength of the clutch and exceed the performance of weaker aluminum or copper rivets. Xtreme PTO clutches are recommended for lawn care professionals and homeowners who depend on their equipment to deliver exceptional performance with a long service life.
