The ROP Shop Electric PTO Clutch for Cub Cadet, MTD 1863, 1864, 2086, 2176, 2185, 2186, 2206

What It Is

The ROP Shop Electric PTO Clutch engages and disengages the mower deck blades on select Cub Cadet and MTD lawn tractors. It’s designed for gas-powered garden tractors with hydrostatic or manual transmissions that use a 12V electric clutch assembly.

Fitment & Compatibility

Check your model number first. This clutch fits Cub Cadet/MTD models: 1863, 1864, 2086, 2176, 2185, 2186, 2206. Also compatible with MTD 700-0370, 700-0370A, 700-0370B, 700-0370C, 700-0370D, and Cub Cadet 717-04008, 717-04008A, 717-04008B.

Verify these before buying:

• Deck size: Works with 42” to 54” decks, but confirm your pulley diameter (typically 4.5” or 5”). Measure your old clutch’s pulley.
• Shaft size: Requires a 1” diameter crankshaft. Measure yours if unsure.
• Wiring: Single-wire (ground through chassis) or two-wire (dedicated ground). Check your harness connector type.
• OEM vs aftermarket: This is an aftermarket replacement. OEM part numbers are listed above—cross-reference with your existing part number.

Key Things to Know

• Quality: Decent for the price, but some users report shorter lifespan than OEM (2–3 seasons vs 5+). Inspect for burrs on the pulley edge before installing.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench, multimeter). Expect 1–2 hours. Disconnect battery, remove belt, unbolt old clutch, wire new one, and torque to 35–45 ft-lbs.
• Common gotchas:
  • The air gap must be 0.010–0.015”. Use a feeler gauge. Too tight = drag, too loose = no engagement.
  • The included hardware may be low-grade. Use thread locker on bolts.
  • Test engagement with battery voltage before full reassembly—if it doesn’t click, check ground connection.
• Belt alignment: If your deck vibrates after install, recheck pulley alignment with a straightedge.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn OEM clutch and can handle basic mechanical work. Skip it if you want maximum durability or have a high-hour commercial mower—OEM is better for heavy use. For occasional residential mowing, this is a solid value.
