What It Is

The Aeagle 505287301 is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower deck blades on select Husqvarna, AYP, and John Deere lawn tractors and zero-turn mowers. It’s a direct replacement for OEM part numbers 505287301, 287301, and AM126100, and equivalent to Warner 5219-1, 5219-108, and 5219-8.

Fitment & Compatibility

Before buying, verify these three things:

• Model fit: Confirmed for John Deere LX266, GT225, GT235, GT245, RZ4623, LX277, LX279, LX288. Also fits many AYP/Husqvarna tractors using the same 505287301 clutch. Check your machine’s model number against the listing.
• Physical measurements: The clutch has a 1-inch bore, 3.5-inch diameter pulley, and 4-inch overall diameter. Measure your old clutch to confirm these match.
• Electrical & mounting: Uses a standard 2-wire connector (12V DC). Mounting bolt pattern is 3-bolt, 2.75-inch bolt circle. Ensure your deck pulley and belt alignment match.

Note: This is an aftermarket part, not OEM. It’s built to the same specs but may have slight cosmetic differences. If you need exact OEM appearance, buy the Husqvarna/John Deere branded unit.

Key Things to Know

• Quality: Rated 4.6/5 from 16 reviews. Users report reliable engagement and no premature failure, but aftermarket clutches can vary. Expect acceptable performance for residential use.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set, multimeter) and about 1-2 hours. Disconnect battery first. The hardest part is often aligning the belt and adjusting the air gap (0.010–0.015 inch).
• Common gotcha: The clutch may come with a pre-set air gap, but always check and adjust it after installation to avoid slippage or drag. Also verify the wiring connector matches your harness—some older tractors may need a pigtail adapter.
• Belt compatibility: Uses a standard 3/8-inch or 1/2-inch deck belt, depending on your model. Confirm belt size before ordering.

Should You Buy It

If you need a budget-friendly replacement for a worn or failed electric PTO clutch on a compatible Husqvarna, AYP, or John Deere machine, this Aeagle unit is a solid choice. It’s not for heavy commercial use, but for residential mowing it’s a reliable, easy-to-install alternative to OEM parts at roughly half the price. Double-check fitment and air gap, and you’re good to go.
