Finally found the problem! Took the tractor to a local kioti dealer and he really had no idea what he was doing, kept the tractor 3 weeks and told me there was some trash in the lines and the control valved needed to be replaced. When I picked up, it leaked down while watching it even faster and it was obvious the valved was not changed. Took the tractor 8 hours to my original dealer Little Tractor and equipment and they isolated it to the left cylinder within a 1/2 hour. They opened it up and the plastic packing was rolled and damaged. They replaced it, no more leak down and the trip was not that bad, got to spend some quality time with the in-laws.
