ACEBRI 717-1708 PTO Clutch Replacement for CUB Cadet: LT1018 LT1170 LT1515 LT1527 LT1600 LT1800 717-1708 Mower Clutch

What It Is

This is an aftermarket PTO (Power Take-Off) electric clutch that engages and disengages the mower blades on select Cub Cadet lawn tractors. It’s designed to replace a failed OEM 717-1708 clutch on models like LT1018, LT1170, LT1515, LT1527, LT1600, and LT1800.

Fitment & Compatibility

Before buying, verify your Cub Cadet model number (found on a sticker under the seat or on the frame). This clutch fits only the specific LT series models listed. It will not fit newer XT or ZT series zero-turns. Measure your existing clutch: the OEM 717-1708 has a 1-inch shaft bore, 3-bolt mounting pattern, and approximately 4.5-inch outer diameter. If your deck is 42–46 inches, this clutch is likely correct. Check your old clutch’s resistance with a multimeter (typically 2–4 ohms across the coil terminals) to confirm it’s the clutch, not a wiring or switch issue.

Key Things to Know

• Quality vs. OEM: This ACEBRI clutch is aftermarket, not genuine Cub Cadet. Expect slightly lighter construction; some users report shorter lifespan under heavy use.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set, multimeter). Requires removing the drive belt, unbolting the old clutch, and reconnecting the wiring harness. Budget 1–2 hours.
• Common gotcha: The wire connector may not match your tractor’s plug perfectly. You might need to splice or use bullet connectors. Also, ensure the clutch air gap (0.010–0.015 inches) is correct after installation; too tight or too loose will cause slipping or failure.
• Torque spec: Tighten the center bolt to 30–35 ft-lbs. Overtightening can warp the rotor.

Should You Buy It

If your Cub Cadet LT series is 5–10 years old and you’re on a budget, this is a solid fix. It’s not for heavy commercial use or if you want OEM reliability long-term. For occasional residential mowing, it’s a good value. If you need a drop-in match with no wiring fuss, buy the genuine Cub Cadet 717-1708 (typically $150–180).
