Nice looking build George. Having a mower that low to the ground actually makes it almost a pleasure to drive because you don't have to worry as much about flipping.Put a nice big wheel on that sucker and you won't even get sore.
By the way, I wonder if there's some reason why we all wind up painting our mowers insane colors. Everyone in my group paints theirs fluorescent green, pink, bright blue, and Fluorescent orange ( mine).
