HQPASFY 02004878P Billet Pulley PTO Clutch, Compatible with Cub Cadet M48 M54 M60 Tank L48 L60, Replace 02004878, Wire Harness Bearing Upgrade, 150ftlb HiTorque, Counter Clockwise Rotation

What It Is

This is a heavy-duty billet aluminum PTO clutch designed to engage and disengage the mower deck blades on specific Cub Cadet zero-turn mowers. It’s built for commercial or tough residential use, delivering 150 ft-lb of torque in counter-clockwise rotation.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This clutch fits Cub Cadet Tank L48, L60, and M48, M54, M60 models. It replaces OEM part number 02004878. Measure your existing clutch bolt pattern and shaft diameter (typically 1-inch bore, 3-bolt pattern) to ensure match. Not compatible with clockwise-rotation decks or older Cub Cadet models without the same PTO mounting specs. Check your wire harness connector type—this includes an upgraded harness, but verify pin layout matches your mower.

Key Things to Know

• Torque & Build: 150 ft-lb rating means it handles heavy grass and wet conditions better than stock stamped clutches. Billet aluminum dissipates heat faster, reducing warping risk.
• Installation Difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and mechanical comfort. The wire harness upgrade may require splicing or adapter if your mower uses a different connector.
• Rotation: Counter-clockwise only. Do not install on a clockwise deck—will not engage properly and can damage the PTO.
• Common Gotcha: The upgraded bearing is quieter and longer-lasting, but verify the pulley diameter matches your belt length (typically 4.5-inch OD). If your belt is worn, replace it simultaneously.

Should You Buy It

Right for you if you own a compatible Cub Cadet Tank or M-series zero-turn, need a high-torque upgrade for frequent or heavy mowing, and are comfortable with moderate DIY installation. Skip if your mower requires clockwise rotation, or if you prefer a lower-cost stamped steel option for light residential use. With only 2 reviews, reliability data is limited, but the billet construction suggests better longevity than OEM.
