What It Is

This electric PTO (Power Take-Off) clutch engages and disengages the mower deck blades on Cub Cadet garden tractors. It’s designed for models like the 1863, 1864, 2086, GT2186, and GT2523, and is a direct replacement for OEM part numbers 717-3403, 717-3403P, 917-3403, 5218-6, and 7-06038.

Fitment & Compatibility

Before buying, verify your exact model number (e.g., 1863, GT2186) and check the deck size—this clutch typically fits 44–60 inch decks on these tractors. Measure the clutch’s outside diameter (usually around 4.5–5 inches) and the shaft diameter (commonly 1 inch or 1-1/8 inch) to confirm. Also inspect the wiring connector style: some Cub Cadet models use a two-pin flat connector, while others have a round plug. If your tractor has a different connector, you may need a wiring adapter or to splice wires. This is an aftermarket part, so it may not have the exact same tolerances as the OEM Cub Cadet clutch.

Key Things to Know

• Quality concerns: With a 1.0/5 rating from only 2 reviews, expect potential issues like premature bearing failure, poor engagement, or incorrect fit. Many aftermarket clutches for these models have mixed reliability.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and likely a puller to remove the old clutch from the crankshaft. Allow 1–2 hours.
• Common gotchas: The air gap between the clutch and rotor may need adjustment (typically 0.010–0.020 inches). Also, check that the pulley belt alignment matches your deck—misalignment can cause belt slip or damage.
• Warranty: Aftermarket parts often have limited or no warranty. Confirm return policy before purchase.

Should You Buy It

This clutch is a budget-friendly option if you’re on a tight timeline and can’t wait for an OEM replacement, but the low rating and potential fit/quality issues make it a gamble. It’s best for experienced DIYers who can handle adjustments and are willing to risk a short lifespan. For a more reliable fix, consider spending extra on an OEM Cub Cadet clutch (e.g., 717-3403) or a higher-rated aftermarket brand.
