My New Holland TC 40 won't start. Turn the key. Once glow plug light goes out, oil pressure light stays on. No noises. Won't start. Any idea what I should check?

Could be one of the Safety Switches (neutral, PTO, seat, etc.) Jiggle all of them and try again. This winter, I had the same issue with my NH T2310 (also 40hp), I sprayed electronics cleaner in the seat safety switch plug/connection, and problem solved.

Did you check the fuses?

Today, I sprayed electronics fluid on the seat safety and the battery contacts and wire brushed them. When I tried to start it, both the oil pressure light and battery light came on very dim. I did not have the chance to check the fuses. Will do that tomorrow. Should I try to jump it first? Could it just be a dead battery?

From your first post, it did not sound like a dead battery. However, if you did not turn the key off after the no-start situation, it's probably dead now. It would be better to put a charger on the battery than to jump start it, because jumpstarting only complicates the situation that your are trying to troubleshoot. Make sure the key is turned to "off". Put a battery charger on it, and check the all the fuses. After 6 or so hours on the charger, give it a try. The next step would be to use a meter to look for power at the small wire to the solenoid while turning the key to "start".

My TC40DA has been showing a problem with the safety switch on the high-low speed selector. You have to jiggle it sometimes. When it is not in the exactly correct position, the glow plug lights, oil pressure lights and battery light comes on, but nothing when turning the key. Sounds like you have a safety switch problem like others suggested. Simple fix, IF you can find which switch!

My TC 30 shut down on me, found a blown fuse, replaced and it went again. Check your wiring to your rear lights and hazard lights. If the fuse to these blows your tractor will not start. I had the wire holder in my inner fender break and the wires got torn by my rear tire chains.

My TC40D was doing the same this spring, began with slow engine cranking for a week to finally no crank and dash lights dimming. Cleaned my battery terminals and checked ground connection and starter connection and charged the battery. Still had to jump start it to get it running. Once running I checked alternator output, it was good. Only thing left was battery itself. Bought a new one and all is well. Point is, try to eliminate all other potential problems before laying out money for a battery.

Where are you finding the info on the hazard fuse causing a no-start? I have no lights, can't find anything wrong other than the round fuse for the hazard is toast. Would I get dash lights if that fuse is removed (from down by the relays on left side)?
For me it was the key switch. All lights came on turn key nothing. Tap starter. It would start. 2 months later nothing. Did a search here found people having problems with key switch. Went to napa $20. No problem sense. Just my 2cents hope it helps
