Bob,

Assuming the tractor has good starter and a hot battery and it's not 10 below up there:

Has the fuel filter been changed recently? Asuming filter is good and fuel is good, here's a few things to do:

1. Verify that the filter is getting a good fuel supply by opening the bleed valve on the top of the filter. Fuel should flow pretty fast, not just a seep. If you suspect slow fuel flow, it's either a clogged filter (then R&R and bleed system) or there's a restriction in the fuel line or the drain valve in the tank. My old 801 (172 cu. in. diesel) has that problem right now and I'm about to remove the tank and clear the restriction. I believe there may be a screen inside the tank.

2. Once you get good fuel flow and the system is bled, you can also crack the injector nuts, one at a time and see if fuel is "spitting" while turning the engine over. Be careful here--don't open the nuts too much or you'll get a blast of diesel into your skin or eyes. Once fuel is seen/heard spraying around the nut, retighten nut and repeat the step for each injector. At this point you know you have a good injection pump. (If you can't get fuel from the injection pump, then the pump has failed and needs to be rebuilt--that'll run somewhere between $350-$500 depending on type of pump and condition. Some pumps can run up near $1000 to overhaul.) Now if the engine still doesn't start then you have compression problems--either rings or valves.

3. I left out air intake restriction, although this is always more a possibility on paper air filers than the oil bath types.

See if any of this narrows down the problem and repost with more info--year & model of tractor wouldn't hurt either.
