My Oliver 1850 will not start. I went out on Saturday to start it and the motor turned over and fired right off. I went out Sunday to start it again, turned the key and nothing happened. It did not even click. I charged the battery for about 45minutes, went to start it and still nothing. I then went and tried jumping the starter, I made I had a good connection but still nothing. I have checked all wiring connections over and over and tightened any that I thought could be an issue. Last night I tried using a screw driver on the started solenoid and get the tractor started that way. All the solenoid did was arch, but the started would still not turn over. The tractor is a negative ground. I am new to these tractors so any advice would be appreciated. My only thought is maybe the starter is locked up?
Thanks

Neutral safety switch. Wiggle the daylights out of the shift. I've had to make a jumper wire for my 1550 because the switch is entirely bad. Look for two wires that go back in under the right side of the cowl,right down low by the frame. That's right side as you're on the seat. They're pretty good sized wires. There should be a big plastic slide together connection in each one,probably 4-6 inches up from where it goes under the cowl. Pull those apart and shove a jumper wire in both of them that come down from above to complete the connection like the switch should do if it was working if wiggling the shift doesn't do the trick. Maybe just wiggling the connections will do it.

I did find two wires that run underneath where the driver puts there feet and then comes out just barely into the engine area. One wire has a plastic connector on it and a pink wire connects to it and runs up to my key switch. The other wire looks like it was connected to something at one time but it now just bare wire. Should the one not connected to anything, be connected to something, if so what?
Thanks

It should be hooked to another wire that goes right in to the same harness as the one to the key switch. One curves up to the key switch,the other should be the exiter wire to the solenoid on the starter shouldn't it? All that neutral switch does is complete the circuit,so it would be the same as if a wire went straight from the key switch to the solenoid if the neutral switch wasn't in there. That's my assumption anyway. The wires are so faded they all look the same color so I can't be sure where it comes out of the harness,but that's what makes sense to me. I was going to take a picture,but the camera battery is dead.

a starter is a starter, if you took one in to be tested and they put power to it and it didn't crank the starter is bad. I know the machine is big, but the thing about manual drive is they can be pulled/pushed/run down a hill with the clutch in till enough speed is generated to "pop" the clutch and they will start provided it's the starter or battery that's the problem.

These machines are old school and fairly easy to diagnose and if you think about it, the parts are well used. How much could you put into it and end up with a good machine? Not near as much as it would be worth when you're done.

Replaced several things on my 1850, don't think I have 500 in it yet and it runs great.

The starter maybe stuck, a jerk on the machine may free it. The motor isn't tied up is it?
