John Deere AM120680 Right Front Mower Deck Gauge Wheel Arm — 7/8" Shaft, 0.345" Hole — Fits 54C & 62C Decks (Selected Models)

Replacement right-hand front gauge wheel arm for John Deere mower decks — OEM AM120680. This arm measures 7/8" shaft diameter with a 0.345" arm hole; be sure your original arm has these exact dimensions or the part will not fit. John Deere used multiple shaft sizes (3/4", 7/8" and 1") across different model years and serial ranges, so checking the original part is essential. Also confirm your tractor’s model and serial number: a matching model alone does not guarantee compatibility. If you’re unsure, contact us before ordering and we will verify fitment.
