ACEBRI Electric PTO Clutch Fit for Grass-Hopper 388740 218 430D 220 223 225 226V 227 321D 322D 325 329 428D Clutch, for Big Dog for Hustler 601311 601311K Clutch Lawn Mower Part

What It Is

The ACEBRI Electric PTO Clutch engages and disengages the mower deck blade via an electromagnetic coil. It’s a direct-replacement part for select Grass-Hopper, Big Dog, and Hustler zero-turn mowers with 14–24 hp engines.

Fitment & Compatibility

Before buying, verify these three things:

• Model confirmation: Fits Grass-Hopper 218, 430D, 220, 223, 225, 226V, 227, 321D, 322D, 325, 329, 428D; Big Dog models using OEM 601311/601311K; Hustler models using OEM 601311/601311K. Not compatible with all Grass-Hopper or Hustler variants—cross-check your OEM part number.
• OEM part numbers: Replaces 388740 (Grass-Hopper) and 601311/601311K (Big Dog/Hustler). If your mower uses a different OEM number (e.g., 388738), this won’t fit.
• Measurements: Clutch diameter ~4.5 inches, shaft bore size 1 inch (25.4 mm), 3-bolt pattern on 3.25-inch centers. Measure your existing clutch’s diameter, bore, and bolt spacing before ordering.

Key Things to Know

• Quality vs. OEM: Aftermarket part at ~$120 vs. OEM $250+. Two reviews limit reliability data—expect possible shorter lifespan or minor fitment variance (e.g., slightly thicker shims needed).
• Installation difficulty: Moderate. Requires removing deck, belt, and wiring harness. You’ll need a puller tool for the old clutch and a torque wrench (specs ~30–40 ft-lbs for center bolt).
• Common gotchas: Air gap must be set to 0.010–0.015 inch after install (use feeler gauge). Wiring polarity matters—reverse can cause failure. Check belt alignment; aftermarket clutches may sit 1–2 mm higher than OEM.
• Return policy: Check seller’s return window—some aftermarket clutches have 30-day limits. Test immediately upon installation.

Should You Buy It

This is a budget-friendly option if you’re comfortable with DIY installation and can verify fitment against your mower’s OEM part number and measurements. Skip it if you want OEM reliability, a warranty beyond 30 days, or if your mower is a commercial machine that runs daily—spend the extra on a genuine 601311 or 388740.
