New 2620 won't start---ideas?

[trum979]

Think I have isolated the problem. After checking out every safety switch I could find. I quite accidently discovered that when the engine started and died, that if I just barley touched the key to restart, it would jump to the stop position. So it occured to me that most of us when starting any engine will, as soon as we hear the engine fire will instinctively release the ignition key, as it is spring loaded back to the run position. I my case it seems that the spring was strong enough to flip the switch back to past the run position and to the indent between the run and stop position, thus engaging the stop solinoid. Tefake613, mentioned that his did the same as mine, but seem to get better. Mine seem to get better also, as I used it more. I can only asume that as the newness wore off and the spring in the key switch was not so taught it spring back with less force. Now when I start the tractor, I hold on to the key just enough to keep it from flipping back too fast --- and Waa--Laa. No more starting and dying problems. I know this sounds pretty far out----(but that's my story and I'm stiken too it.)

Sorry to have not found your post earlier. Had the exact same symptoms you described on a B series. Your last post describes the same thing that I found. Replaced the ignition switch and the problem was gone.

I have a problem with my B26 and the ignition. After I start the engine sometimes the light for the glow plug stays on. I don't think the glow plugs are on but the light stays on. I just bump the key and it goes out. Put some CRC on the switch today maybe that will fix it.

I don't know that it's that far out. I started my tractor very early Sat morning (about 28 deg) and it fired right up. As a matter of fact, since the first couple of days I had my tractor, it has started up flawlessly every time. In essence, I don't have the problem anymore.

I tried to re-create your theory with the ignition switch. Mine has a VERY positive stop in the ON position. I even tried to purposefully let it snap back and it would not. You may want to compare it with the ignition on another machine at your dealer and make them replace the switch if it's not right.
