ECCPP Electric PTO Clutch Assembly New Upgraded Design Replacement 5100084 Lawn Mower Clutches Parts fit for Snapper Pro/Snapper/Simplicity/Sears Craftsman/Mcculloch/Massey Ferguson

What It Is

This is an aftermarket electric PTO (power take-off) clutch assembly designed to engage and disengage the mower deck blades on select lawn tractors and zero-turn mowers. It’s a direct replacement for the OEM part number 5100084, used on many Snapper Pro, Snapper, Simplicity, Sears Craftsman, McCulloch, and Massey Ferguson models.

Fitment & Compatibility

Before buying, check the following:

• OEM Part Number Cross-Reference: This clutch replaces OEM number 5100084, but also fits 92-5100, 925100, 5250-100, and 5250-100A. Verify your existing clutch’s part number.
• Deck Size: Typically fits 42” to 54” decks, but confirm your model’s deck size in the manual.
• Shaft Diameter: The clutch bore is 1” (25.4mm) with a 3/16” keyway. Measure your crankshaft to ensure it matches.
• Electrical: 12V DC with a 2-pin flat connector. Check that your wiring harness matches (most Snapper/Craftsman tractors do).
• Brand-Specific Fit: Fits many Snapper Pro (e.g., ZTR models), Simplicity Broadmoor/Regent, Craftsman GT/ST series, and some McCulloch/Massey Ferguson lawn tractors. Always verify your specific model number.

Key Things to Know

• Quality & Durability: This is an aftermarket unit, not OEM. Reviews are mixed (3.8/5), with some reporting shorter lifespan than original. Expect it to work, but not necessarily match OEM longevity.
• Installation Difficulty: Moderate. Requires removing the mower deck, disconnecting the belt, and unbolting the old clutch. You’ll need basic hand tools and a torque wrench (specs: 35-45 ft-lbs for the center bolt).
• Common Gotchas: The wiring connector may be slightly different from the OEM—you might need to splice or use a pigtail adapter. Also, check the air gap (0.010-0.015”) after installation; if it’s off, the clutch may slip or fail to engage.
• Belt Alignment: After installation, recheck belt alignment. The new clutch may sit slightly higher or lower than the old one, causing belt wear or disengagement issues.

Should You Buy It

This clutch is a budget-friendly option for DIYers who need a quick replacement for a Craftsman, Snapper, or Simplicity lawn tractor. It’s not for heavy commercial use or those expecting OEM reliability. If you’re on a tight budget and comfortable with minor wiring adjustments, it’s a reasonable choice—but if you want guaranteed fit and durability, stick with the OEM part.
