8TEN Electric PTO Clutch 917-04180 717-04180 for Cub Cadet GT2544 GT2550 GT2554 LT2042

What It Is

The 8TEN Electric PTO Clutch (917-04180 / 717-04180) engages and disengages your mower deck blades via an electromagnetic coil. It’s a direct-fit aftermarket replacement for specific Cub Cadet lawn tractors with 42″ to 54″ decks, including GT2544, GT2550, GT2554, and LT2042 models.

Fitment & Compatibility

Before buying, verify:

• OEM cross-reference: Replaces Cub Cadet/MTD part numbers 917-04180, 717-04180, 917-04180A, and 717-04180A. Not compatible with other brands.
• Model list: Confirmed fit for Cub Cadet GT2544, GT2550, GT2554, and LT2042. Check your machine’s model number tag under the seat.
• Measurements: Clutch diameter is 4.5″; shaft hole is 1″ with a 3/16″ keyway. Measure your existing clutch to confirm.
• Wiring: 2-wire connector (standard for these models). No adapters needed.
• Deck size: Works with 42″, 50″, and 54″ decks on listed models—deck size doesn’t change clutch fit.

Key Things to Know

• Quality: 8TEN is a solid aftermarket brand. Most users report 2-3 seasons of light-to-medium use. Not as durable as OEM under heavy commercial use.
• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, puller) and about 45-60 minutes. Disconnect battery first.
• Common gotcha: The air gap (0.010″–0.015″) must be set after installation using a feeler gauge. Skip this and the clutch may slip or fail early.
• Noise: Some users note a slightly louder engagement click vs. OEM. Normal for this price point.

Should You Buy It

Buy this if you have a listed Cub Cadet model and want a budget-friendly replacement that works well for residential mowing (1-2 acres). Skip it if you mow commercially or need OEM-level longevity—spend more on a factory clutch.
