Its my gut feeling that Kubota does not like putting a ROPS on there tractors but it is no longer engineers that are designing equipment. It is the "F"ing lawyers and the courts of this land. The new L seris Kubota's have go so many electronic features that you almost don't need a brain to operate one.
What I did to repair mine and I did it in about an hour. I pit a straight edge on a flat piece of steel near the base of the structure and I could only see about 1/16" deflection. So I rasied the loader and secure a come-a-along to it and the ROPS. Then I loosened all the bolts at the first joint just behind the tool box and started takeing up the slack. I actually took it too far but I put a 1/16" SS shim in and slacked off the come-a-long, tightened all the bolts and it is darn near perfect.
