I started my build with a 1988 Rally lawn mower. the frame is a U shape that is open at the top with a 1-2 inch lip at the top. It seemed to be fairly sturdy when moving around(didn't seem to twist very much). there was a spot for the battery that was countersunk about 1/2" lower than the rest of the frame. This area was just forward of my 700 tranny and was getting in the way of the tranny pulley. after cutting this piece out and welding in a new flat panel flush with the rest of the frame there now seems to be a lot of twisting in the frame now. when i pick it up, it now flexes about 2-3" from one corner to the other. I plan to put 1 1/2"x1 1/2" square tubing inside on both sides with cross members on the front and rear, and possibly somewhere in the middle. is this common with this type of frame and would this be a good solution to remedy my current situation?
