2X Gage Wheel Arm AM120680 & AM120681 Replacement for John Deere 54C 62C Mower Decks, 7/8" Diameter Set

What It Is

This is a set of two gage wheel arms (AM120680 and AM120681, left and right) designed to replace worn or broken original equipment on John Deere 54C and 62C mower decks. They support the deck’s front corners, preventing scalping and ensuring a consistent cut height on uneven terrain.

Fitment & Compatibility

Before buying, check these specifics:

• Deck size and model: Fits John Deere 54C and 62C mower decks only. Not for 48C or other models without verifying arm geometry.
• OEM cross-reference: Replaces OEM part numbers AM120680 (left arm) and AM120681 (right arm). If your current arms have different numbers, measure carefully.
• Wheel diameter: Designed for wheels with a 7/8" diameter axle hole. Confirm your existing wheels match this size, or you’ll need to source compatible wheels separately.
• Mounting hardware: Includes bolts and nuts, but check if your deck’s mounting brackets are intact and not rusted or stripped. No modifications required for original John Deere decks.

Key Things to Know

• Quality vs OEM: Aftermarket steel construction is comparable to OEM, but some users report slightly thinner metal. Fine for residential use; heavy commercial mowing may prefer OEM.
• Installation difficulty: Easy—remove two bolts per arm, swap, and reinstall. No special tools needed. Budget 15–20 minutes for both sides.
• Gotcha: Ensure you order the correct left/right pair. The arms are mirror images and not interchangeable.
• Wheel compatibility: If your old wheels are worn or have a different axle size (e.g., 5/8"), you’ll need to buy new wheels separately. This set includes arms only.

Should You Buy It

If you have a John Deere 54C or 62C deck and need a quick, affordable fix for wobbly or broken gage wheel arms, this set is a solid choice for residential mowing. It’s priced well below OEM, and the 5.0 rating suggests reliable fit and function. Skip it if you need a heavy-duty commercial part or if your deck’s mounting brackets are damaged—those will require additional repair.
