AM126100 Gen 3 Electric PTO Clutch Compatible with John Deere Warner Husqvarna AYP Dixon Poulan Lawn Mower GT225 GT235 GT245 GX255 LX280 LX288 LT190 Replace 5219-108, 5219-11, 505287301, 287301, X0327

What It Is

This AM126100 Gen 3 electric PTO clutch engages and disengages the mower deck blades via an electromagnetic coil. It’s designed for lawn tractors with 42–54-inch decks, replacing worn or failed OEM clutches on John Deere, Husqvarna, AYP, Dixon, and Poulan models.

Fitment & Compatibility

Before buying, confirm your machine’s model and deck size. This clutch fits John Deere GT225, GT235, GT245, GX255, LX280, LX288, and LT190 tractors, plus many Husqvarna, AYP, Dixon, and Poulan units with 1-inch or 1-1/8-inch crankshafts. Check your old clutch’s part number—it replaces OEM numbers 5219-108, 5219-11, 505287301, 287301, and X0327. Measure the mounting bolt pattern (typically 3-bolt, 3.25-inch spacing) and shaft diameter to ensure a match. Verify your deck’s PTO pulley size (often 4.5-inch or 5-inch) to avoid belt alignment issues.

Key Things to Know

• Quality vs. OEM: This is an aftermarket Gen 3 unit, not genuine John Deere or Husqvarna. It uses an updated coil design that may be more durable than some OEM versions, but fitment tolerances can vary slightly.
• Installation difficulty: Moderate. You’ll need basic mechanical skills, a puller for the old clutch, and a torque wrench (specs: 35–40 ft-lbs for the center bolt). Allow 1–2 hours.
• Common gotchas: The clutch may require shimming to achieve the correct air gap (0.012–0.020 inches). Also, check your battery and charging system—low voltage can cause intermittent engagement.
• Warranty: Most sellers offer a 1-year warranty, but verify before purchase. Some units may arrive with a loose rotor or bent pulley; inspect immediately.

Should You Buy It

If your OEM clutch is worn (squealing, slipping, or not engaging) and you’re on a budget, this aftermarket replacement is a solid, cost-effective choice for most DIY repairs. It’s best for common John Deere and Husqvarna lawn tractors with 42–54-inch decks—just double-check your shaft size and bolt pattern to avoid returns. Not ideal if you need exact OEM fitment for a rare or commercial model.
