2010 DK45SE stalls when idled

[tractorsam]

I have a 2010 DK45SE HST cab tractor with just over 800hrs on it. When it gets fully warmed up, especially if it痴 hot outside, it is very hard to start. Today, after a couple of hours bush mowing in 30C heat it stalled when I idled it down to disengage the PTO. It would not restart until I opened the throttle almost fully while cranking, after which it very slowly picked up rpm until about the normal idle speed and then quickly picked up from there. Idling it down fully caused it to stop again. After letting it run at a higher idle with no load for a bit I was able to (slowly) idle it all the way down. Once I got it to idle down it is surging at idle. No rough running or other issues I致e noticed. Anyone seen anything else similar before? Thanks, Sam

Sounds like a fuel supply issue, checked your filter lately? With the filter off open the valve to the tank and check flow to make sure something is not plugging your line.

Fuel filter was new about 50hrs ago. Hot start issue was present last summer. No loss of power. Will check flow when I next have a chance. Thanks.

It sounds a little like when gear teeth in my injection pump broke off but I thought that problem was fixed by 2010. I would look, hard, for some kind of fuel flow obstruction (or air leaking into fuel line) first. Possibly water in the fuel.

Def. sounds like supply or just plain old bad fuel.{Bio}
