Lower the heat with Cool Coil Technology Xtreme builds clutches with a proprietary composite coil that lowers the heat level. Xtreme PTO clutches run at approximately 175 degrees Fahrenheit -- a big reduction to the 220 degree temperature produced by typical clutches. The bottom line benefit is that cooler running clutches last longer. The Advantage of Xtreme PTO Clutches All Clutches Look the Same ... Until You Take a Closer Look! At first glance, you may think a PTO clutch is a PTO clutch, but nothing could be further from the truth. At Xtreme, we don't believe in building the cheapest PTO clutch possible. Xtreme upgrades materials and craftsmanship to make its clutches work better and last longer. These extra features deliver a longer lasting clutch that cuts a more beautifully manicured lawn. Take a closer look at the features you'll get with an Xtreme PTO clutch. High performance bearings with high temperature grease Precision machined billet pulleys Stainless steel bands for exceptional strength High durability stainless steel rivets Impact resistant, watertight wire harnesses Precision Engineered Bearings with High Temperature Grease PTO clutch bearings go through punishing treatment with heat, vibration and high operating speeds. It takes a tough bearing to withstand all of that. Xtreme uses a highly engineered bearing with a proprietary blend of high temperature grease and harder races to deliver a longer service life. The high temperature grease is rated to deliver more than double the protection of what's required. CNC Machined Billet Pulleys Xtreme upgrades the pulleys on its PTO clutches. Billet pulleys are used on performance applications like NASCAR engines because they don't spread under load liked formed pulleys do. When a formed pulley "spreads," the belt sinks deeper into the groove and slows down. That also causes the speed of your blades to slow down, which affects the cut of turf grass. Faster blade speeds deliver a cleaner cut of grass. With Xtreme pulleys, you'll experience stronger, quieter and smoother operation with more stable and faster blade speeds. Stainless Steel Brake Rivets Xtreme PTO clutches are made with the finest craftsmanship and materials down to the smallest details. The rivets may seem like a minor thing, but they truly are not. Xtreme cuts no corners and uses stainless steel for its brake rivets, which are much stronger than aluminum and copper ones used on some other clutches. The strength of the rivets maintains the integrity of the clutch and is an important factor in safer operation. Integrated Watertight Connectors Xtreme uses a "watertight" connection with three layers of protection at the clutch body. Some other PTO clutches try to get by with a flimsy plastic connector that can leave exposed wires. Xtreme goes the extra mile in protecting the connection because of the tough environment where PTO clutches are used. Heat, water, sticks, rocks, tree stumps, and curbs won't pose as much risk to the Xtreme Triple Protected Wire System.
