Super High Torque 150ft-lbs (OEM is 105) BIGBearing 717P05398 Solid Steel Billet Pulley PTO Clutch for Cub Cadet ZT2-60 ZT3-60 ZTS2-60 2019 to 2023 w/Replaceable Pulley Bearing Lawn Mower Clutch

What It Is

This is a heavy-duty aftermarket PTO (Power Take-Off) clutch for Cub Cadet ZT2-60, ZT3-60, and ZTS2-60 zero-turn mowers (2019–2023). It replaces the stock OEM clutch (105 ft-lbs) with a super high torque 150 ft-lbs unit, featuring a solid steel billet pulley and a replaceable bearing for longer service life.

Fitment & Compatibility

Before buying, verify your mower’s model year (2019–2023 only) and deck size (60-inch). This clutch is a direct bolt-on replacement for OEM part numbers 717P05398 and similar. Remove the old clutch and measure: the pulley diameter must match your belt setup (typically 4.5" or 5"). Check that your PTO wiring harness has the same connector type (two-pin flat) and voltage (12V DC). If your mower uses a different pulley size or connector, this won’t fit without modifications. Also confirm your deck belt is in good condition—a worn belt can damage the new clutch.

Key Things to Know

• Torque upgrade: The 150 ft-lbs rating is 43% higher than OEM (105 ft-lbs). This provides stronger blade engagement and better performance in thick or wet grass, but may slightly increase belt wear.
• Replaceable bearing: Unlike many stock clutches, the pulley bearing can be swapped separately (saves replacing the whole unit later). Check the bearing part number (likely 6203-2RS) before ordering a replacement.
• Installation difficulty: Moderate—requires removing the deck, disconnecting the PTO wiring, and unbolting the old clutch. You’ll need a 1/2" drive socket set and a torque wrench (tighten to 35–40 ft-lbs). No special tools needed, but allow 1–2 hours.
• Common gotcha: The solid steel billet pulley is heavier than stock. This can cause slight vibration at high RPM if your engine mounts are worn. Also, the clutch engages with a louder click than OEM—normal for high-torque units.

Should You Buy It

Buy this if you mow heavy or wet grass regularly, need stronger blade engagement, or want a clutch with a replaceable bearing to avoid full replacements later. It’s overkill for light residential use on dry, manicured lawns—stick with the OEM 105 ft-lbs unit for those conditions. At $319.99, it’s a premium upgrade that pays off for demanding mowing.
