Oil & Fuel Low fuel light

[PioneerMan]

So I was wrapping a project as it got dark and didnt have any diesel on hand. Hit the red mark but got it in soon after. Made me wonder, what happens if you went empty on a cut? I thought with most diesels it is major bad news, is it the same with these little guys? Is hitting the light hard on the lift pump or anything? Anyone here run out before?

It depends on whether your tractor has a self-bleeding fuel system. I'm sure you could find out in your manual somewhere. It probably does since even my JD790 had an electric fuel pump to prime the system. So if you ran out of fuel and the engine quit...just put more fuel in, turn the key on, and the electric pump should prime the system. It did say in my manual something about might have to crank the engine over longer than normal.

If it's not self bleeding you have to bleed the air out of the line - there's usually the procedure for that in the manual too if your tractor is not self bleeding...

As for whether it is hard on a tractor, I would say no way! My reasoning is, to shut the thing off normally all you are doing is depriving it of fuel, so as far as the engine is concerned, I would think it would be the same as if you turned the key off.

My JD 2320 is self priming.

Fill out your profile so we know what tractor you are asking about.

I too suspect same as jwinner said, 'cept maybe it being the same as turning the engine off, as there is a fuel solenoid shutoff that shuts off the fuel supply.

I will update it, 4320 cut. Good to know, thanks guys.

I've had two 4320 0pen station tractors (2007 and 2010) and the fuel gauges on both registered much lower on the indicator than the actual fuel level. Example, indicator below quarter mark with "low fuel" flashing but tank was actually half full. Dealer replaced sender unit on the first and it didn't make any difference, if anything it was worse by a small amount. Some others here on tbn have mentioned the same thing on the 4X20 series so I think it is just the way it is unless JD has fixed it on the 2011 models.

Like Sunnyside360's 4320's, my 5225's (2006) fuel gauge shows also much lower on the indicator than the actual fuel level. With mine, the tank is actually half full when the light comes on. Appears to be a common problem.
