I use the box blade as weight. I looked at a few different mfg's, and the Howse has 1/4" steel side plates, where a lot of the othes have 1/8". It has worked out well for us, I've run in low range, 4 wheel drive and go for several lots in a row back filling curbs, keep the side plate on the curb, and it fills in nice behind it. I'm far from an expert with it yet, and I'm sure I'll pick up speed and ability as I go.
Really looking forward to working on our own property, we had 80 acres when we lived in Michigan, really miss that!! I kept 44 acres of it mowed with a Ford 3000 diesel and a flail mower.
