RAREELECTRICAL New Electromagnetic Pto Clutch Compatible With Ferris Evolution 52" Flail Mower Series Massey Ferguson Mcculloch 3000 Series Simplicity Series Series Snapper S125xt Series 5100084Sm Ccw

What It Is

This is an aftermarket electromagnetic PTO (power take-off) clutch designed to engage and disengage the mower deck blades on select zero-turn and riding mowers. It’s a direct replacement for failing OEM clutches on Ferris, Simplicity, Snapper, and McCulloch models, specifically for 52-inch flail mower decks and 3000 series machines.

Fitment & Compatibility

Before buying, verify these three things:

• OEM part number cross-reference: This clutch replaces Snapper part #5100084SM and is listed for Ferris Evolution 52" flail mowers, Massey Ferguson, McCulloch 3000 Series, Simplicity Series, and Snapper S125XT. Double-check your machine’s original OEM part number—if it’s not 5100084SM or a direct cross, it won’t fit.
• Shaft size and rotation: This clutch is designed for a CCW (counter-clockwise) rotation shaft. Measure your engine crankshaft diameter (typically 1” or 1-1/8”) and ensure it matches.
• Deck type: It’s specifically for flail mower decks on Ferris Evolution 52". If your deck is a standard rotary blade deck, this may not be the right clutch—confirm with your model’s parts diagram.

Key Things to Know

• Aftermarket quality: Rated 5.0/5 from only 2 reviews—limited feedback. Expect it to work as a functional replacement, but long-term durability is unproven compared to OEM.
• Installation difficulty: Moderate. You’ll need basic hand tools, a puller for the old clutch, and a torque wrench to tighten the center bolt to spec. Air gap adjustment (typically 0.010–0.015”) is required after mounting.
• Common gotcha: The clutch wiring harness may not match your mower’s connector. Be prepared to splice or replace the plug.
• Voltage check: Ensure your mower’s electrical system supplies 12V to the clutch coil (most do). Low voltage causes slippage and premature failure.

Should You Buy It

Buy this if you need a budget-friendly replacement for a 5100084SM clutch on a compatible Ferris, Simplicity, or Snapper model and are comfortable with basic mechanical installation. Skip it if you want OEM reliability, have a different OEM number, or need a clutch for a standard rotary deck—stick with the factory part for guaranteed fit and support.
