OEM Welded Latch Retainer John Deere L 110 120 130 D105 125 X 125 145 AM133942

What It Is

This OEM welded latch retainer (AM133942) secures the mower deck to the tractor frame on select John Deere lawn tractors. It holds the deck’s lift linkage in place, preventing the deck from sagging or detaching during operation.

Fitment & Compatibility

Direct fit for: John Deere L110, L120, L130, D105, D125, X125, X145, and similar models with a 42- or 48-inch Edge or Accel Deep deck.

Before buying:

• Verify your model number (stamped on the frame near the left rear wheel). This retainer does not fit X300 series or older L100 non-“L” models.
• Measure the latch pin diameter—this retainer works with 3/8-inch pins. If your deck uses a 1/2-inch pin, you need a different part.
• OEM part (AM133942) is identical to the factory-installed retainer. Aftermarket versions may have thinner metal or looser welds—this one is welded, not bolted.

Key Things to Know

• Quality: OEM-grade steel with a welded joint; more durable than stamped or bolted retainers. Expect it to outlast the deck if kept greased.
• Installation: Easy—remove the old retainer’s cotter pin and washer, slide the new one on, and re-pin. No special tools needed.
• Common gotcha: The retainer can wear out if the deck is left in a raised position for long periods. Check for cracks or elongation of the latch hole before replacing.
• Price note: At $40.94, it’s mid-range. Cheaper aftermarket versions exist but often fail within a season due to poor welding.

Should You Buy It

If your John Deere L100/D100 series deck latch has broken or is visibly worn, this OEM retainer is the right fix—it’s a direct, durable replacement that avoids the fit and longevity issues of cheaper aftermarket parts.
