What It Is

The ILONPA AM126100 is an aftermarket electric PTO (power take-off) clutch that engages and disengages your mower deck blades. It’s designed for select John Deere lawn tractors, including the LX, GT, LT, GX, SST series models listed.

Fitment & Compatibility

Before buying, verify your mower’s model and serial number. This clutch replaces OEM John Deere part numbers AM126100, 5219-1, and 5219-221. It fits deck sizes from 38” to 54” on models like LX255, LX277, LX279, LX280, LX288, GT225, GT235, LT190, GX255, SST15, SST16, and SST18. Measure your existing clutch’s bolt pattern (typically 3-bolt, 4.5” diameter) and shaft diameter (1” or 1-1/8”) to confirm compatibility. Check that your mower uses a 12V DC system and that the electrical connector matches (usually a 2-pin flat connector). If your model isn’t listed, cross-reference your OEM part number.

Key Things to Know

• Quality vs. OEM: Aftermarket unit; may have slightly different bearing or winding quality. 4.7-star rating suggests good reliability, but inspect for burrs or loose fasteners before install.
• Installation difficulty: Moderate. Requires jack stands, socket set, and possibly a puller to remove old clutch. Expect 1–2 hours. Disconnect battery negative terminal first.
• Common gotchas: Air gap must be set to 0.010–0.015” after install (use feeler gauge). Torque center bolt to 35–45 ft-lbs. Wiring polarity matters—reverse leads can blow fuse.
• Warranty: Check if seller offers a 1-year warranty; aftermarket clutches may fail faster under heavy use.

Should You Buy It

If your John Deere’s PTO clutch has failed and you want a budget-friendly replacement that’s well-reviewed, this ILONPA unit is a solid choice. It’s best for DIYers comfortable with moderate mechanical work and who don’t need OEM branding. Avoid if you want a dealer-installed part or need a clutch for commercial-grade mowing (heavy daily use).
