What It Is

This is an aftermarket PTO (power take-off) clutch designed to engage and disengage the mower deck blades on commercial zero-turn mowers. It’s built to replace OEM clutches on Grasshopper, Toro, and certain Oregon-equipped models, typically used in heavy-duty mowing operations.

Fitment & Compatibility

Before buying, verify these three things:

• OEM part numbers: Cross-reference your current clutch’s part number with this list—388771, 388767, 388769, 388768, 606242 (Grasshopper); 104-7756, 105-1671, 94-4632 (Toro); 33-189 (Oregon). If yours isn’t listed, it likely won’t fit.
• Mower models: Confirmed fit for Grasshopper 618, 718K, 720K, 721, 725, 727K2. Not all Grasshopper or Toro models are covered—check your specific model tag.
• Physical measurements: The clutch must match your shaft diameter (typically 1” or 1-1/8”), bolt pattern, and overall height. Measure your old clutch’s shaft bore and mounting holes before ordering. This aftermarket part may differ slightly from OEM dimensions, so compare closely.

Key Things to Know

• Quality: Rated 4.6/5 from 10 reviews—generally reliable, but as an aftermarket part, it may have shorter lifespan than OEM (especially under heavy commercial use).
• Installation difficulty: Moderate. You’ll need basic mechanical skills, a puller for the old clutch, and torque specs for the mounting bolts. No wiring harness issues reported, but double-check electrical connections.
• Common gotchas: The clutch may need a break-in period (10–15 minutes of light use) to seat properly. Some users note slight noise at first. Verify belt alignment after install—misalignment can cause premature wear.
• Return policy: Since it’s an aftermarket part, confirm the seller’s return window and condition requirements. Fitment issues may not be covered if you’ve installed it.

Should You Buy It

If you need a budget-friendly replacement for a Grasshopper or Toro zero-turn and you’re comfortable with a moderate DIY install, this clutch is a solid value. Avoid it if you demand OEM longevity for daily commercial use or if your mower isn’t on the compatibility list.
