I put it to work today moving dirt and found out I needed a weight box to help keep the back tires from spinning.
I took a piece of 2" sq. tube, a 24" 3x2 solid bar for bumper and an old mc travel trunck loaded with scrap steel sealed with a 80lb sack of quickcrete, This slides into the receiver hitch. there is some room left on top of the concrete that extra weight can be added.
Pic's tomorrow.
