JD6300 starving for fuel

[CBBC]

I have a 6300 loader tractor which works great for intermittent loader work which it gets daily, 5 - 10 minutes to load a couple scopes of manure - off for half an hour...probably not great for the engine, but its what we do with it and it never fails.

The problem arises every time we actually try to do some real work with it. We put a side arm flail mower on to mow the dykes and ditch banks. We drive as slow as we can go in the lowest gears but reved up to 540 pto rpm.

It will run fine for a couple hours and then you can hear it sound like its running out of fuel. If you don't stop and go for a coffee break it will shut down by itself. Or you turn a corner coming up an incline out of a field it will just die.

There is always fuel - at least 3/4 tank still when it stops. Usually I wait 10 min and it will start right up. I head back to the yard, re fuel, have lunch and go through the same thing a few hours later.

If you work for an hour no problem. I always keep the tank full so it is not that. I've changed the filter and drained the water out regularly.

My guess is the tank intake. Is there a tank filter or could it be cracked and suck air when it gets low? Any thoughts or advice would be appreciated?
Thanks, Grant

Tried giving it a new fuel filter?

Besides installing new fuel filter as previously suggested check for good fuel flow from tank to filter. Is fuel tanking venting??

There is a tank filter, roll up the mat on the clutch pedal side, remove inspection plate in cab floor, clean off top of tank, 4 phillips head screws, 2 hoses and a connector for the fuel guage and lift out the fuel sender unit assembly.
The filter is on the end of it.
The fuel pump only runs for priming, not all the time so dont go looking for an electrical fault because you cant hear the pump going all the time.

Yes the filter has been changed.

Is the cap vented or is there another tank vent? Regular fuel
flow seems fine - when I crack the drain on the fuel filter while
running...any other way to check fuel flow?

Thanks, I will check this out in the morning.

My 6200 did that last fall and I had recently changed the in-tank fuel pump. I eventually found the screen on the pump had clogged from trash I apparently didn"t get out when I replaced the pump. It was clogged just enough to cut out at high RPMs when I was using my pecan harvester but would run ok at a lower speed. The way I found the problem was to put a clear in line filter before the fuel filter and when it quit, there was no fuel in the clear filter. Hope this helps.

Great Idea...Thanks

As easy as this sounds I have more pressing issues...I will get to it next week - everything is mowed now so I'm onto the next crisis.

I will post back a new thread to let you know what I find when I open it up.

Thanks for all the input. Grant
