New Holland TC35 Will Not Start

[Ghost River Retrievers]

Yesterday I was moving some dirt around to make a mound a bit lower and less steep. Everything was going smoothly and I was nearly done when I decided that I needed to take a view from the top of the mound. So I stopped the tractor, lowered the bucket, put the shifters into neutral position, reduced the RPM to lowest possible setting, and set the brake. Of course, I've gone thru the same process innumerable times. But this time when I raised my rear off the seat, the engine shut down. "No problem," I thought.
So after viewing my handiwork and seeing a few spots that needed a bit more sculpting, I climbed back on the tractor, put on my seatbelt, turned the key partway to warm up the glow plugs, waited for the light to go out, turned the key to start it ... NOTHING HAPPENED. So my initial thought was wrong ... there IS a problem.
So where do I look first? (The on-line "yellow pages" will be the second or third place that I look.)
At first I suspected the seat switch, but then it seems to me that it wouldn't have been running in the first place. I suspect that a safety switch somewhere is telling the tractor that it shouldn't start/run because it's in gear ... does that make sense?
How do I figure out if it's the "in gear" safety switch?
Where else should I look and what else should I consider?
FWIW, the battery is brand new and is fully charged.
Thanks for any help!

Not sure if you have a clutch or HST. if HST, it could be the "neutral" position switch is not adjusted or the pedals need adjusting before it will start.

I can start my LS with the brake set and range selector in N without being in the seat. I usually start it this way standing beside the tractor so it has a couple minutes to warm up and I can do other things, like open the gates, etc.

If a gear, then maybe the neutral switch if it has one or the brake switch are the only 2 I would think could cause this. Did you try shifting gears and back to neutral?

Edit: PTO didn't get switched on did it?


Good luck.

It's got a clutch, so maybe the brake switch or neutral switch.
Thanks for your suggestions!

for one if you have been using it you wont need to use the glow plugs to start it again.

another possibility for no start ...battery or terminals

You got off the seat. The tractor died. That sure sounds to me like the seat switch MAY be the culprit. Check it out as well as any nearby wiring for broken or bad connections.

When I have an issue like this I cycle all the levers and pedals, then put all in a position to start, brake set, transmission in neutral, etc. I have moved the PTO lever getting on or off just enough so it would not start.

Thanks for the suggestions!
I'm heading out now to check things over and will report back.

Dang-it! I looked at and messed with the seat switch, pto switch, clutch switch and break switch ... they all look fine. I also cycled through the levers and pedals several times, trying to start it throughout the process.I didn't have time to check the switches by by-passing, but hopefully I'll have time to do that tomorrow.

Bad ground to the chassis.
Thanks all!

Ah yes, that is a common one that presents itself in many, many ways. Glad you figured it out.
