We have a Kubota M105X. Doesn't want to start after it has been running, and you shut it off. Try to restart and it just clicks. If the tractor hasn't ran for a few hours or overnight, it will start fine most of the time. I have twisted on the positive cable when it doesn't start, and sometimes it then starts. So I assumed it was the positive battery cable, purchased a new one from Kubota and installed it. Yesterday it started fine the first time, ran it for a while and will only click and not start. Then this morning, it sat overnight, started fine. Ran for awhile and warmed it up. Shut it off and now it starts again. Did this a second time and it started right up. This is an intermittent problem that happens on and off again. Last week I had ran it for a while, moved some round bales, shut it off and tried to restart it and it would not start. Twisted on the positive bat cable and still only click, no start. Let it sit overnight, and then it started just fine. Could the starter solenoid work like this, when it gets warm, it will not engage??
