Electric PTO Clutch Compatible with John Deere Eztrak Z445 X500 Series Replacement Part Number AM134397 AM141536 5219-62 5219-87 Xtreme X0383 X0383-K

What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades on select John Deere zero-turn and lawn tractors. It’s a direct replacement for the OEM clutch when the original fails (won’t engage, noisy, or seized).

Fitment & Compatibility

Check these before buying:

• Models: Fits John Deere Eztrak Z445, Z465, Z645, Z655, X485, X495, X500, X520, X530, X534, X540, X584, X590, X720, X724, X728, X729, X734, X738, X739, X740, X744, X748, X749, X754, X758, X759 series.
• OEM numbers: Replaces John Deere AM134397, AM141536, and aftermarket equivalents 5219-62, 5219-87, Xtreme X0383, X0383-K.
• Measurements: 3-bolt mounting pattern (common JD small-frame), 1” shaft bore. Verify your existing clutch has 3 bolts and a 1” shaft – not the 1-1/8” or 4-bolt versions used on larger Deeres.
• Wiring: Two-wire connector. Confirm your harness matches (some older models may need a pigtail adapter).
• Deck size: Works with 48”, 54”, and 60” decks that use a standard electric clutch – not for 42” or 72” decks.

Key Things to Know

• Quality variance: Aftermarket clutch from a brand like PTO or Xtreme often matches OEM performance but may have slightly different bearing quality. Some users report shorter lifespan (2-3 seasons vs 4-5 for OEM).
• Installation difficulty: Moderate. Expect 1-2 hours. You’ll need a socket set, torque wrench (tighten bolts to 35-40 ft-lbs), and a puller to remove the old clutch from the crankshaft.
• Common gotcha: The air gap (0.010-0.015”) must be set correctly after installation – if the clutch chatters or drags, the gap is off. Also, check the PTO belt condition; a worn belt can cause premature clutch failure.
• Warranty: Most aftermarket clutches carry a 1-year warranty – keep your receipt and packaging.

Should You Buy It

If you’re on a budget and need a functional replacement for a mid-size John Deere (Z445, X500 series), this clutch is a solid value at $108. It’s not as durable as OEM but works well for homeowners mowing 1-2 acres. Skip it for commercial use or if you want OEM reliability – spend the extra $60-80 on a genuine John Deere clutch.
