I agree the balance is where it is at. The casters don't work very well in grass until they are very large. So what I do is put straight wheels on the back that will handle 85% of the load then I carry the other end as I move it. This also allows me to make the legs that have no wheels to have adjustable bolts to level with. I'll post some pics in a few days of the one I'm making now that is like that.Gizmo wrote: Balance is important so do you homework to get the big ones to carry around 85% of the load and it's will be very easy to move without being "tipsy"
