Kubota 2010 L5740 HST Running RoUgH

[nebraskasparks]

Did all my servicing a couple weeks ago. New hydraulic fluids and filters, fuel filter, air filter, oil and filter. Cleaned everything and greased everything. Ran great for a week. Did some weed tilling for about 20 minutes today when tractor started running rough, rpm swinging from 300 to 1400 (where I had it set manually). Let it run at idle for 5 minutes and appeared to stabilize. Put it under load with tiller and after 5 minutes...same thing. Do I have some sort of fuel contamination or has anyone run across this before with the 5740? This tractor has done nothing except perform perfectly for the past 5 years till today.

I've never run into this problem with my L5740, but have with a couple of our BXs and it turned out to be fuel related. We drained the fuel, blew the lines, changed filters and added Power Service.

I'm surely no mechanic, so anything beyond that and I'd have to get a mechanic out to look at it.

Good luck.

Sounds like maybe some air in the injector lines? Recheck the filter bowl gasket. Try running with the fuel vent valve open to purge it. If the tank level is below half, try filling it up. If running improves, the transfer pump could be bad.

Thanks fellas...out to the shop to bleed the diesel. Was always told that something would happen where I would have to do this!

Thanks...bled injector per instructions on orangetractor.com works great.
