ACEBRI PTO Clutch for Husqvarna for Wright Stander 539106880 7140001 71410001 5218-52, for Wright Stander 48 52 61" Clutch, for Husqvarna iZ 4217 4218 4821 for Warner: 5218-211 5218-175 (Crank 1)

What It Is

The ACEBRI PTO Clutch is an aftermarket electric clutch that engages and disengages the mower deck blades on select Husqvarna and Wright Stander zero-turn mowers. It replaces OEM part numbers 539106880, 7140001, 71410001, and Warner 5218-211/5218-175, and is intended for commercial/residential mowers with 48", 52", or 61" decks.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This clutch fits:

• Husqvarna: iZ 4217, 4218, 4821 (check your serial number for 1-inch crank shaft)
• Wright Stander: 48", 52", 61" models (verify your OEM clutch part number)

Critical measurements to check:

• Crank shaft diameter: Must be 1 inch (25.4 mm)
• Bolt pattern: 3-bolt or 4-bolt? The Warner 5218 series uses 3 bolts; measure center-to-center distance
• Voltage: 12V DC (standard for most zero-turns)

OEM cross-reference: This replaces Husqvarna 539106880, 7140001, 71410001, and Warner 5218-211, 5218-175. If your original clutch has a different number (e.g., 5218-195), measure carefully—bolt patterns vary.

Key Things to Know

• Build quality: At $125, this is a budget aftermarket option. Some users report shorter lifespan than OEM (2-3 seasons vs. 4-5), but for light residential use, it’s adequate.
• Installation: Moderate difficulty. You’ll need a puller to remove the old clutch from the crank shaft (do not hammer). Torque the center bolt to 35-45 ft-lbs. New hardware is included, but reuse your original wiring harness connector if it’s in good shape.
• Gotcha: The clutch may have a slightly different engagement sound (louder click) than OEM. This is normal for aftermarket units, but if it chatters or slips under load, check air gap (should be 0.010-0.015 inches).
• Warranty: Check seller return policy—some aftermarket PTO clutches have limited or no warranty. Test immediately on install.

Should You Buy It

If you own a compatible Husqvarna or Wright Stander and need a budget-friendly replacement for light residential mowing, this clutch works. But if you run a commercial operation or need maximum reliability, spend more on an OEM unit—the price difference is worth avoiding downtime.
