Xtreme Outdoor Power Equipment X0384 PTO Clutch Compatible with/Replacement for John Deere Z225, Z425 and Z445, Serial No. 040001-100000, and Z465 EZTrak AM136787, AM137323, 5219-225, 5219-88

What It Is

The Xtreme X0384 is an aftermarket PTO (power take-off) clutch designed to engage and disengage the mower deck blades on select John Deere Z225, Z425, Z445, and Z465 EZTrak zero-turn mowers. It replaces OEM part numbers AM136787, AM137323, 5219-225, and 5219-88.

Fitment & Compatibility

Check serial number range first: This clutch fits John Deere Z225, Z425, and Z445 models with serial numbers between 040001 and 100000. For the Z465 EZTrak, it fits serial numbers 040001 and up.
Deck size doesn’t matter – this clutch works with any deck size on those models.
Measure your old clutch: Confirm the shaft diameter (typically 1 inch) and bolt pattern (3-bolt, 4-inch spacing) match.
Not compatible with newer John Deere models or those outside the serial range – verify your mower’s serial plate before ordering.

Key Things to Know

• Aftermarket quality: Xtreme is a known aftermarket brand – expect similar performance to OEM, but not identical materials or lifespan.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, puller) and electrical knowledge to disconnect/reconnect the clutch wiring. Expect 1–2 hours.
• Common gotcha: The clutch uses an electromagnetic coil – check that your battery and charging system are in good condition; low voltage can cause slippage or failure.
• Warranty: Typically 1 year – confirm with seller before purchase.

Should You Buy It

If you need a direct-fit replacement for a Z225, Z425, Z445, or Z465 within the specified serial range and want to save over OEM pricing, this is a solid choice. It’s not for heavy commercial use, but for residential or light-duty mowing, it delivers reliable engagement. Avoid if you need a guaranteed OEM match or are outside the serial number range.
