Re: mystery solved!
Ken,
I agree with you. I don't think it has to do with the float position or lack thereof. It's the high push point from the PT to the deck. A better explanation is like pushing a grocery cart. It goes along well on a flat hard surface. Once the going gets tough (ie: imagine pushing a grocery cart through beach sand), the overturning load gets high. With the bushhog, when the going gets tough (pushing through heavy brush etc), the PT pushes to meet this resistance. The overturning load will heavily load the front castors, and deck structure in between the push point and the castors.
It looks like the welder understood the load points and placed the stiffners in the right locations. Let us know how this holds up after time.
