8TEN Belt PTO Clutch Kit for Cub Cadet 2166 2150 2135 2155 2140 2146 2145 954-3055A 754-3055A 717-3385A 917-3385A

What It Is

This PTO clutch kit engages and disengages the mower deck blades on Cub Cadet lawn tractors. It’s a direct-fit replacement for the factory electric clutch assembly on select 2100-series models with 42-inch or 50-inch decks.

Fitment & Compatibility

Before buying, confirm your Cub Cadet model is one of these: 2166, 2150, 2135, 2155, 2140, 2146, or 2145. Also check your OEM part number—this kit replaces 954-3055A, 754-3055A, 717-3385A, and 917-3385A. Measure the clutch shaft diameter (typically 5/8-inch) and bolt pattern (three bolts on a 3-inch circle). If your deck is 46-inch or non-standard, verify clearance as aftermarket clutches can vary slightly in thickness. The kit includes the clutch, pulley, and hardware—no extra bearings or wiring adapters needed.

Key Things to Know

• Quality vs. OEM: This is an aftermarket kit, not genuine Cub Cadet. Users report it holds up well for residential use, but may have a slightly shorter lifespan under heavy commercial loads.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and about 1–2 hours. The hardest part is accessing the clutch bolts under the tractor—use a jack or ramps.
• Common gotcha: The wiring connector may not match your harness exactly. You may need to splice or swap connectors—check your old clutch plug before starting.
• Belt alignment: After install, verify the pulley sits flush with the deck belt path. A shim kit (not included) can fix minor misalignment.

Should You Buy It

If you own one of the listed Cub Cadet models and need a reliable, budget-friendly replacement for a worn or seized PTO clutch, this kit is a solid choice. It’s best for homeowners mowing standard lawns—not for heavy commercial use or odd-sized decks. Just be prepared for a possible connector mismatch and basic mechanical work.
