John Deere 425 AWS
Hi everyone,

I have a 425 John Deere AWS (Kawasaki Engine FD620D-1993, I believe), and when I turn the key to start the tractor, the starter rolls the engine over real slow (not fast enough to start it). Then when I turn the key back off- the starter is still doing the same thing- (rolling the engine over very slowly) even though the key has been turned back off. To stop it from doing that I have to unhook the battery. I have replaced the battery, and during the summer had put in a new timing relay switch in it because it would randomly stall out on me. The relay switch fixed the stalling problem, but did not help the problem I have with trying to start it in the winter months. Anybody have any ideas as to what the problem might be? It only does it in the very cold weather. During the summer- it starts and runs fine.
I'd appreciate any suggestions.

Rick

Welcome to TractorByNet!

I moved your thread to the John Deere Lawn & Garden forum. :)

Bad starter relay. Some times the contacts get burnt which can cause them to pass very little power to the starter and they can also stick together which would make the starter keep spinning until you disconnect the battery.

I'm having a similar problem with my 99 JD445. When I turn the key the starter immediately engages. It is supposed to turn the ignition on to activate the fuel pump prior to tuning the key farther to engage the starter. It just started doing this out of the blue, and I can't seem to diagnose the problem. Checked grounds and all relays seem to be energizing. I won't start and I cannot hear if the fuel pump is energizing at the same time. I will watch to see if someone can solve your problem as they may be related. If I find a solution I will pass it on.

You should here the fuel pump humming when key is in on position. If not, and you are sure the relays are closing with minimal resistance, might be the fuel pump itself.

I would think your key switch just went bad. If you turn to the on position and the starter starts turning before you get to the start position on the key switch, I would think the only thing that could be wrong is the actually key switch has failed.
