AM120681 Left Hand Front or Right Hand Rear Mower Deck Gage Wheel Arm for John Deere Mower Decks 54C and 62C Diameter 7/8"

What It Is

This is a replacement gage wheel arm for John Deere 54C and 62C mower decks. It mounts the front left or rear right gage wheel, helping the deck follow ground contours and prevent scalping.

Fitment & Compatibility

• Deck size: Fits John Deere 54C and 62C decks only. Not for 48C, 60D, or other deck models.
• Position: Left-hand front or right-hand rear. Verify your old arm’s orientation—this is not reversible.
• OEM equivalent: AM120681 replaces the original John Deere part. Aftermarket, so check for slight finish differences versus OEM.
• Shaft diameter: 7/8" – measure your wheel’s bore or old arm’s shaft with a caliper. If your wheel has a 3/4" bore, this won’t fit.
• Model cross-check: Common on X300, X500, X700 series with 54C/62C decks, and older 400/400X series. Confirm your deck’s stamped model number before ordering.

Key Things to Know

• Quality: Aftermarket, but solid steel construction. Some users report paint chipping faster than OEM, but function is identical.
• Installation: Moderate difficulty. You’ll need a jack to lift the deck, a socket set, and possibly penetrating oil for rusted bolts. Expect 30–45 minutes.
• Common gotcha: The bushing inside the arm can seize if not greased periodically. Apply grease to the shaft during installation to extend life.
• Wheel not included: This is the arm only—you’ll need to reuse or buy the wheel separately.

Should You Buy It

If your original AM120681 arm is bent, cracked, or the bushing is worn, this is a direct, budget-friendly replacement. It’s fine for homeowners and light commercial use, but if you need the exact OEM finish or warranty coverage, stick with John Deere’s part. Otherwise, this saves ~$15–20 with no functional downside.
