Electric PTO Clutch 160889 1772388 Fits for Craftsman Cub Cadet John Deere STX38 STX46, 5217-35, 532160889, 717-1459, 917-1459

What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades on lawn tractors. It’s designed for mid-size residential mowers from Craftsman, Cub Cadet, and John Deere STX38/STX46 models.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Fits 38" and 46" decks (STX38, STX46). Measure your deck width to be sure.
• Model/brand: Listed for Craftsman, Cub Cadet, and John Deere STX series. Check your mower’s model number against the OEM cross-references: 160889, 1772388, 5217-35, 532160889, 717-1459, 917-1459.
• Physical dimensions: Measure your old clutch’s shaft diameter, bolt pattern, and overall height. This aftermarket clutch may differ slightly from OEM specs—compare before installing.
• Electrical: Requires 12V DC with a standard two-wire connector. Verify your mower’s wiring matches.

Key Things to Know

• Aftermarket quality: This is not a genuine OEM part. Expect variable quality—some users report shorter lifespan than OEM. Check if it includes a warranty (often 1 year).
• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, socket set) and a puller to remove the old clutch. Wiring is straightforward but verify polarity.
• Common gotcha: The bearing may be noisier than OEM. If you hear grinding or wobble after install, the clutch may be defective or misaligned.
• Fitment check: The pulley diameter and belt groove must match your deck belt. Measure your old pulley width (typically 3/8" or 1/2") to avoid belt slip.

Should You Buy It

Buy this if you need a budget-friendly replacement for a Craftsman, Cub Cadet, or John Deere STX38/STX46 and can handle moderate DIY installation. Skip it if you want guaranteed OEM fit and durability—spend more on a genuine Cub Cadet or John Deere clutch for better longevity and less hassle.
