My Father In-Law Just Purchased A JD X720SE With 62" Mower ($10,500 Out The Door). Anyone Found A Way To Disable The Reverse Switch On X700 Tractors? (Shuts Off Mower When You Back-Up) We So Far Can't Find The Switch. It Has Back-Up Lights, Will We Lose Them When We Disable This Function? Please help If You Know, Thank You.
