shutting fuel off after usage

[Karl Kostman]

Hey guys I grew up with a 48 JD A and my Dad would always shut the tractor off by shutting the fuel off on the sediment bowl valve and also because of possible leaks through the carb and into the cylinders. OK I understand that perfectly. I am running a 59 JD 730 diesel is there any reason I need to shut the fuel off on this tractor after I am done using it or can I just leave the fuel valve on all the time?

The manual says nothing about this on the 730 but then it says nothing about it on the A either.
Thought please?

On a diesel you leave it on but on a gas you turn it off

Dads rule was to shut off the fuel when parked at the end of the day. Even on another tractor (AC) it was no fun to have a flooded engine (if the needle valve did not hold) when you wanted to start the tractor and do something.

That is only true on a gas tractor but not true with a diesel tractor

If you shut the fuel off on a diesel and let it die from fuel starvation air gets in the lines and you need to bleed them before she re starts......

Thanks much guys and I would never turn the fuel off to shut the diesel down. Bleeding the line just isn't that fun.
Thanks again guys!

We had a diesel that you had to shut the gas off or it would flood and be hard to start.

Funny story about shutting off the fuel on a 720 diesel. Neighbor had one and dropped it off to have me do oil and filter changes on it. So I proceeded to start it up and drive it around the place to warm it up before changing the oil. I called him up and said what is wrong with this thing as it was a dog. Ran good but did not have any power ? He said he forgot to tell me he shuts the fuel off when sitting as it tended to leak into the engine oil. Turned on the fuel and it ran GREAT ! I still can't believe it ran as good as it did and as long as it did with the fuel bowl shut off. I also fixed his internal leak down problem too. Delivery valve holder on the injection pump needed tightening as it was leaking.
