312H - No crank

Recommended Posts

Phan

Hello - I am in the middle of a cut. I turned off the engine checked the engine the oil level - but the engine does not crank.  

No crank the engine has happened on off, I wonder if it is the issue with the ground, safety seat, key switch, or the PTO. I notice that the PTO handle is lose.  

Please advise - what should I do from there? Thank you!

Possible switches can be that the motion lever is not in neutral, try wiggling the lever sometimes it doesn’t trip the switch, the other is the PTO lever switch, wiggle the PTO as well see if that helps.  Does your tractor have working indicator lights?

If Karl's suggestion with the PTO is not the problem then it is time to do some basic electrical maintenance.

Nylyon - Yesterday, after posting, I went back to push to the garage but decided to start and it cranked. I was able to finsh the cut. 

I still cannot not explain why - I did try as your comments each time when there was no crank. I definatively will check every possible issue that may have.

Do you know the model number of your tractor?

We should have a detailed wiring file that shows the wiring individually for each circuit. With that you can confidently follow a circuit looking for the fault. So much easier.

A small brass bristle brush will do the trick.
