Robert, just out of curiosity, did you ever get the issue resolved where your CK20 would not back over the 2x4 or drive through the small depression in your yard while in high range?
As for flaming you, no, I will agree with you. Others will flame both of us. But NH is upping the HP in their small frame tractors (the little TC24 is being bumped up to 26hp so in the same size package as the CK20 you can get 6 more HP) and it appears that Kubota is taking their redesign to make slighly smaller machines with similar HP to their older models, so in effect they seem to be upping the HP to size/weight ratio. JD has already begun rolling out their new models and they have more HP than their older versions.
