I have started to try and fix up an old john deere 140. I started by replacing the battery and that is as far as I have gotten. The battery was installed and there was nothing when I turned the key. I just want to know what I should try to fix first or if I need to start an extensive parts list. I am new to this thing and I welcome any help.

Do you have a voltage tester? Time to start checking connections on the wiring, and then checking where and when you have power.

Thank you I will start there.

What year is the 140? Do you have a serial number? There are some significant wiring differences based on the serial number of the machine. Does it have an external coil or magneto ignition?

Unless some one has changed the motor, it has a external coil. With the key in the on position, a volt meter should read about 12 volts at the coil. When u turn the key, do u hear a click sound and nothing happens, or does just nothing happen. A click sound would mean the starter solenoid is getting voltage. If no click is heard, check for voltage at the starter solenoid. Corrosion and or loose connections can cause nothing to happen when u turn the key. When u check for corrosion or loose connections, disconnect the battery first. I will post a pic of the wiring diagram asap.

you can have a bad pto safety and/or a netual-starter switch that are bad
there are located between the starter switch and the coil
if one is bad it does not allow the current to the coil
some of the 140 have a electric pto clutch - which has an electric switch - which can also be bad
you should check the wiring and switches with an ohm meter
look at the wiring diagrams - they should help you with the wiring
without electric pto

And please test the key switch. We were at a fair and my 112 didn't start, some month ago. We didn't find a failure. We thought, the key switch could be damaged....
Some days later, we were back at home again, the tractor started...

Welcome! I have a 140 and sometimes need to wiggle the hydro lever in neutral.

Thank you so much for all this help. i took the volt meter out today put the battery on and tightened it down. Then the tractor turned over. Which was a great sound. This tractor was my grandfathers and he passed a year ago.
Now I have to deal with the Stuck Carb. Any suggestions on how to get that unstuck i was thinking Wd-40

glad for the update about your 140
for freeing up a carb you might want to soak for a few day
some use lemon juice, pine sol and other thing
there was a post about clean a carb here lately about it
I think I found the post, but there can be others post about it
