What It Is

This is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower deck blades. It’s designed for Husqvarna, Craftsman, and Cub Cadet lawn tractors with 42- to 54-inch decks, including specific older models like the 1863, 1864, 2086, 2176, 2185, and the Xtreme X0125 series.

Fitment & Compatibility

Before buying, confirm these three things:

• Model number: Cross-reference your mower’s model number with the OEM part numbers 582948801, 717-3390, or 917-3390. This clutch fits Husqvarna 127170X, Craftsman 917.3390, and Cub Cadet 1863/1864/2086/2176/2185. It also fits the Xtreme X0125 and X0125-K.
• Physical dimensions: Measure your old clutch’s shaft diameter (must be 1-inch), overall height (approx. 3.5 inches), and bolt pattern (typically three bolts on a 4.25-inch circle). If yours differs, it won’t bolt up.
• Deck size & pulley: This clutch uses a 2.5-inch pulley. Verify your belt and deck pulley match—some newer decks use a different pulley diameter or offset.

This is an aftermarket replacement, not OEM Cub Cadet. It’s electrically identical but may have slightly different paint or label.

Key Things to Know

• Quality: Users report it’s a solid aftermarket unit with good engagement and no premature failure. Six reviews are all 5-star, but that’s a small sample. Expect similar life to OEM if installed correctly.
• Installation difficulty: Moderate. You’ll need a puller to remove the old clutch, a torque wrench (specs: 30-35 ft-lbs for the center bolt), and basic wiring skills. The three-wire connector is standard, but double-check your harness plug—some older tractors use a different connector.
• Common gotcha: The clutch must be shimmed to the correct air gap (0.010-0.020 inches). If it’s too tight, it drags; too loose, it slips. Most aftermarket clutches come pre-shimmed, but verify before installing.
• Belt alignment: After installation, check that the pulley aligns with the deck belt. Misalignment causes rapid belt wear and poor engagement.

Should You Buy It

If you need a reliable, affordable replacement for a Husqvarna, Craftsman, or Cub Cadet tractor from the 1990s or early 2000s (models listed above), and you’re comfortable with a moderate DIY install, this clutch is a solid choice. It’s not for newer machines with different shaft sizes or pulley offsets. For the price, it’s a good value—just confirm your model on the fitment list first.
