Hello, after having my tractor towed to the the local Kubota dealer The issue was diagnosed to two hoses being clogged with crud, not sure what crud means but it seems to be working now and the next time it snows I will know more. The part numbers replaced are TD350-42642 and T3680-42632. Hopefully this helps others out there since about 12 people that the local dealership knows of with L6060 have this issue, BTW not covered under warranty even though this has been happening since the tractor was six months old.
