What It Is

The electric PTO clutch engages and disengages the mower deck blades via an electromagnetic coil. It’s designed for lawn tractors and zero-turn mowers from Cub Cadet, MTD, Troy-Bilt, Craftsman, and White Outdoor that use a 12V electric clutch system.

Fitment & Compatibility

Cross-reference your OEM part number against the list: 917-05209, 717-04174, 917-04174, 717-04552, 717-04552A, 917-04552, 917-04552A, 917-05001, 717-1774, 917-1774, or Warner 5219-25/5219-64. This clutch also replaces MTD 917-05001A and 917-04174A.

Check physical dimensions before ordering: shaft diameter (typically 1" or 1-1/8"), overall height, and bolt pattern. Measure your old clutch’s mounting holes—center-to-center distance matters. Common deck sizes are 42", 46", 48", and 54", but size alone doesn’t guarantee fit.

Confirm voltage (must be 12V) and wiring connector type (2-pin flat or round). Some models use a different plug; you may need a pigtail adapter if the connector doesn’t match.

Brands confirmed: Cub Cadet (LT, GT, Z-Force series), MTD (700/800 series), Troy-Bilt (Bronco, Pony), Craftsman (LT1000/2000/3000), White Outdoor (LT models). Not for zero-turns with 14-pin connectors or older non-MTD platforms.

Key Things to Buy

• Quality: Aftermarket clutch. Expect functional but potentially shorter lifespan than OEM. Check for aluminum vs. steel pulley—steel lasts longer.
• Installation difficulty: Moderate. Requires removing deck, belt, and center bolt. Torque center bolt to 30-40 ft-lbs. Gap between clutch and engine housing must be 0.010–0.020".
• Common gotchas: Air gap must be set with feeler gauge (included with some units). Loose belt tension or worn pulley bearing can cause premature failure. Use a multimeter to test coil resistance (should be 3–5 ohms) before mounting.
• Warranty: Typically 90 days to 1 year. Verify before purchase.

Should You Buy It

If your mower’s PTO clutch is dead (no engagement, grinding, or free-spinning pulley) and you want a budget-friendly replacement for a weekend repair, this is a solid option. It’s not OEM quality, but it’s 30–50% cheaper than a genuine Cub Cadet part. Best for older machines where cost matters more than longevity. Avoid if you need a direct OEM replacement or have a zero-turn with a non-standard connector.
