John Deere 4440 won't start

[sbs]

Worked on tractor after work with no success. Batteries check out good all connections are clean.
Put a new starter solenoid on it didn't help. Tried jumping it didn't help. Turned the lights on and turning the key just a slight dim. All the starter does when you turn the key is click, next turn maybe no click. I'm thinking maybe the starter needs replaced. Any thoughts?

Have someone help you. Use a test light, clip the ground of the light on a the base of the solenoid, the point on the connection from the solenoid to the starter, have that someone turn the key to the start position, if the test light lights and starter does not run, you have a bad starter.

Have you checked voltage at starter solenoid both at battery wire and small post that connects to key switch?

Yes starter could have a short. You could short across on solenoid with a screwdriver BUT be sure trans is in PARK and better yet have someone in the operators seat.

I would guess the ground wires inside the starter are burned up.Low voltage and cranking too long will do it.

Check the safety switch on the trasmission. If the wires are loose or the switch is bad could cause no start.
