AM120680 Right Hand Front Mower Deck Gage Wheel Arm for John Deere Mower Decks 54C and 62C (Selected Model), 7/8" Shaft Diameter 0.345" Hole

What It Is

The AM120680 is a right-hand front gauge wheel arm for John Deere 54C and 62C mower decks. It supports the front corner of the deck to prevent scalping and maintain cutting height consistency.

Fitment & Compatibility

• Deck models: Fits John Deere 54C and 62C decks (check your deck model number stamped on the deck housing).
• Shaft diameter: 7/8" — measure your old arm’s shaft before ordering.
• Bolt hole: 0.345" diameter — confirm this matches your deck’s mounting bracket.
• OEM vs aftermarket: This is an aftermarket replacement for OEM part AM120680. Quality varies; read recent reviews for your specific deck year.
• Model years: Not universal across all 54C/62C decks — verify your deck’s serial number range with the seller’s compatibility list.

Key Things to Know

• Installation difficulty: Easy — 15-30 minutes with basic hand tools (socket set, wrench). No special skills needed.
• Common gotcha: The shaft can seize to the deck bracket from rust. Use penetrating oil and a mallet to free the old arm; replace the bushing if worn.
• Quality: Aftermarket arms may have thinner metal or looser tolerances than OEM. Check for burrs on the shaft before installing.
• Pre-assembly check: Ensure the wheel spins freely on the arm. Some aftermarket arms require light lubrication at the pivot.

Should You Buy It

At $30.50, this is a budget-friendly fix for a worn or bent gauge wheel arm on a 54C or 62C deck. It’s ideal if you’re comfortable with simple mechanical work and don’t need OEM durability for heavy commercial use. If you mow frequently on rough terrain, consider OEM for longer life.
