I was thinking of something along those lines with an eliptical shaped slot on the sides of the mechanism to act like a camshaft...thereby when you lift the lever a bit and go forward it would drive the mechanism downward in the slot as you go forward. Therefore...reversing would take the weight off it and you could lock the handle in some kind of position to allow you to turn and operate the machine to get in line for the next line of aeration. I already made 2 receiver brackets that are mounted on the front crossbrace of the machine...they fit a standard 1 1/2 sq. male piece thats used for automotive trailer hitch balls. I sometimes use it for moving trailers around .....
