John Deere Original Equipment Plate #AM137437

What It Is

The John Deere Original Equipment Plate #AM137437 is a stamped steel mounting plate used to attach a mower deck to the tractor frame via the lift linkage. It is designed for select John Deere lawn tractors with 42-inch or 48-inch Edge/Edge Xtreme decks.

Fitment & Compatibility

Before buying, verify your model: this plate fits John Deere tractors like the D100, D105, D110, D120, D125, D130, D140, D155, D160, D170, and LA series (LA105, LA115, LA125, LA135, LA145, LA155, LA165, LA175). It is not compatible with the X300, X500, or Z-series. Check your deck measurement (42” or 48”) and look for a stamped AM137437 on your existing plate. This is OEM, so it matches the original dimensions exactly—aftermarket alternatives may vary in thickness or hole alignment. Measure your deck lift bracket spacing (center-to-center) to confirm; it should be roughly 2.5 inches.

Key Things to Know

• OEM quality: Thicker steel than most aftermarket plates; resists bending under heavy mowing.
• Installation difficulty: Moderate. Requires removing the mower deck and disconnecting the lift linkage. Have a socket set and penetrating oil ready for rusted bolts.
• Common gotcha: This plate does not include the lift rod or pins—buy those separately if they’re worn.
• Check for cracks: Older plates often crack at the weld points. Replace both sides if you notice uneven lift.

Should You Buy It

Buy this if you own a compatible John Deere D or LA series lawn tractor with a 42” or 48” deck and your existing plate is bent, cracked, or has elongated holes causing deck sway. It’s the right choice for a direct, no-guesswork replacement that restores deck leveling and lift geometry. Skip it if your plate is fine—just grease the linkage instead.
