OCPTY Electric Lawn Mower Clutch Replacement for Warner:5219-107 5219-147 5219-98,for Troy BILT:717-05122A 917-05122A,for CUB Cadet/MTD:717-05122A 917-05122A 717-04552 717-04552A PTO Clutch

What It Is

This electric PTO clutch engages and disengages the mower blades on select Troy-Bilt, Cub Cadet, and MTD lawn tractors. It replaces several OEM and Warner part numbers, making it a direct drop-in for machines needing a clutch with a 1-inch shaft and standard bolt pattern.

Fitment & Compatibility

Before buying, confirm your mower has a 1-inch diameter crankshaft (common on many tractors with 42–54-inch decks). Check your old part number against this list:
OEM: 717-05122A, 917-05122A, 717-04552, 717-04552A
Warner: 5219-107, 5219-147, 5219-98
Brands: Cub Cadet, MTD, Troy-Bilt (specific models like LT series, RZT, and some Huskee).
Measure the clutch’s overall diameter (roughly 5.5 inches) and bolt pattern (three holes at 120 degrees). If your deck uses a different shaft size (e.g., 7/8-inch or 1-1/8-inch), this won’t fit.

Key Things to Know

• Quality: Aftermarket replacement; one review with 5.0 stars suggests it works, but long-term durability is unverified compared to OEM.
• Installation: Moderate difficulty—requires removing the mower deck, accessing the clutch, and torquing the center bolt to spec (usually 45–55 ft-lbs). Have a puller tool if the old clutch is stuck.
• Gotchas: Check the wiring harness plug shape—some MTD models use a flat 2-pin connector that may need splicing if the new clutch has a different plug.
• Noise: A slight whirring sound when engaged is normal; grinding or slipping indicates misalignment or a bad install.

Should You Buy It

If you need a budget-friendly replacement for a worn-out PTO clutch on a Troy-Bilt, Cub Cadet, or MTD tractor with a 1-inch shaft and your model matches the listed numbers, this is a solid bet. Skip it if you want a brand-name OEM part or have a rare deck size—check fitment carefully first.
