John Deere Tractor Won't Start? Causes, Checks and Common Problems

Why a John Deere Tractor Won't Start

Dead or weak batteries and corroded cables, a failed starter or relay, air in the fuel system, clogged fuel filters, a bad lift pump, seat and neutral safety switches, glow plug or intake heater faults, and low compression on high-hour engines.

What You Can Check Before Calling

Battery voltage, fuel level and filters, the safety switches, and any codes on the monitor. If the engine cranks strongly but won't fire, stop cranking and call — repeated cranking damages the starter and can hydro-lock a cylinder.
