HiTorque130ftlbs (OEM 87) BIGBearing Clutch RZT42 RZT50 & 10a PTO Switch 917-04622 917-04183 5219-99 GT1A-MT09 fits Cub Cadet White ZT42 ZT50 ZT5000 MTD Troy-Bilt 2009 Mustang RZT42 RZT50

HD Clutches are designed at HD Clutch and Assembled in the USA. Higher Torque: 130 ft-lbs vs OEM at 87 ft-lbs (87ftlb Ogura or 105ftlb Warner). We add a few more windings to our coils to provide the maximum gripping strength to prevent damaging micro-slipping during tough cutting conditions. The HD Switch BIGBearing design addresses the #1 reason clutches fail with a larger tougher pulley bearing. Machined Billet Pulleys: It is easy to damage formed pulley and 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. 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.

• IMPORTANT NOTE: This Clutch replaces Ogura GT1A-MT09 or Warner 5219-99. The Ogura LOOKS VERY different; however, this clutch replaces it. Please don't return based on looks. The Ogura is only 87ftlbs and that is likely why your clutch failed.
• High Torque Coil: This OEM Upgrade has 130ftlbs of Torque (OEM is 87ftlbs). Higher Torque Means this Clutch holds Strong Even in the Toughest Cuts and Prevents Overheating caused by slippage.
• BIGBearing: The Pulley Bearing Takes a lot of abuse and is often the first thing to fail. We use a Larger Pulley Bearing for a much longer life. We also designed our Billet Pulley with a snapring making the bearing replaceable.
• 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.
• Premium C3 Bearings: To Combat Heat HD Designed and Spec’d these bearings with C3 Clearances, Premium High Temperature Grease and on Most Models a Larger Tougher Bearing.
