4 shorts, looks like some quality work you turn out there in your shop.
My mods are not as extensive as i lack a good farm shop. But the quick draw bar is handy, as are the greasable MMM dolly and storage wheels. One handy mod that cost very little was two 2"X 6" on the BH out rigger shoes. I used carrage bolts to mount them to the shoes, with wing nuts for quick removal, then on the portion of the 2X6 that contacts the earth, I picked up some gator skins (truck retreads) along the interstate, sawsall to fit the pad. Now i can drop the out riggers on pavement or concrete without damaging the walks.
