505287301 5219-108 Blade Clutch & PTO Switch 582107601 fits Husqvarna Z242 Z248 EZ4824 EZ5221 EZ5226 LSZ4622 LSZ5422 LSZ5424 RZ4219 RZ4619 RZ4620 RZ4621 RZ4824 RZ5422 RZ5424 RZ Mower

High Torque Coil: Prevents the Clutch from Slipping and Overheating. Higher Torque Means this Clutch holds Strong Even in the Toughest Cuts.
Tough Billet Pulleys: Billet Pulleys Reduce Belt Wear and Maintain Perfect Blade Speed. Our Billet Pulley Design uses a Snap Ring and Allows for Bearing Replacement.
Cool Coil Technology: We use a Proprietary Composite Material Instead of Plastic. This Allows the heat to Escape the Clutch Faster. Less Heat = Longer Life
Premium C3 Bearings: HD Designed and Spec??d these bearings with C3 Clearances, Premium High Temperature Grease and on Most Models a Larger Tougher Bearing.

HD Clutches are designed by HD Clutch and Assembled in the USA. We use Machined Billet Pulleys for several reasons. The first, formed pulleys are damaged easily, and any damage (even a small stone nick) damages the belt with every rotation. With our Billet Pulley design we include a snap ring so the bearing is replaceable, making this clutch rebuildable. Lastly and most importantly, a Billet Pulley does not spread during tough loads and maintains a Constant blade speed. Allow us to explain: When a pulley spreads it opens up and allows the belt to sink in slightly, this acts like a smaller pulley and slows the belt speed, which slows downs the blades and adds additional wear to the belt. Higher Torque: We add a few more windings to our coils to provide the maximum gripping strength to prevent damaging micro-slipping. Clutches all run very hot; we use a composite material instead of plastic to allow the heat to dissipate much faster. This makes the HD Clutch run much cooler; extending the bearing and clutch life. HD Clutch wrote the Bearing specifications to include Premium C3 Rated Bearings and high temperature rated synthetic grease to combat heat. Less Heat = Extended Life.
