Yoursme AM136328 Left Hand Front or Right Hand Rear Mower Deck Gage Wheel Arm for John Deere Mower Decks X300 X500 Series 48 in and 54 in

What It Is

This Yoursme AM136328 is an aftermarket replacement gage wheel arm for John Deere lawn tractors, designed to support the deck’s front-left or rear-right wheel. It’s used on 48-inch and 54-inch mower decks found in the X300 and X500 series (e.g., X304, X360, X534).

Fitment & Compatibility

• Deck size: Only fits 48-inch (48C, 48S) and 54-inch (54C, 54S) decks. Do not use on 42-inch or 62-inch decks.
• Model series: X300 and X500 series only—not for older 100-series or 400-series tractors.
• OEM cross-reference: Replaces John Deere part AM136328 (left-hand front) and AM136329 (right-hand rear). Verify your existing arm’s part number.
• Position: Left-hand front or right-hand rear. The arm is symmetrical; flip it for the other side, but check that the wheel bracket orientation matches your deck.
• Measurements: Overall length ~9.5 inches, bolt hole center-to-center ~2.5 inches. Confirm your deck’s mounting bracket spacing before buying.

Key Things to Know

• Build quality: Steel construction with a painted finish. Some users note the paint chips faster than OEM, but the metal holds up well under normal use. Not as thick as genuine John Deere, but adequate for residential mowing.
• Installation: Easy DIY—remove one bolt and pin, swap the arm, and reattach. No special tools needed. Expect 10–15 minutes per side.
• Common gotcha: The included hardware may be too short for thicker decks. Keep your original bolts and washers. Also, the wheel may not roll as smoothly as OEM; a light grease on the bushing helps.
• Warranty: Yoursme offers a 1-year replacement warranty. Save your packaging for a return if fitment is off.

Should You Buy It

This is a solid budget pick if your OEM arm is bent or rusted and you don’t need heavy-duty commercial use. It’s correct for X300/X500 48/54-inch decks, cheap, and easy to swap. Skip it if you want thicker steel or a perfect paint match—stick with genuine John Deere for that.
