The Trailer is 12 Ft Long. The sides are 2 ft high, We just ripped a sheet of plywood in half. We started to attach them with bolts, but then we just started using self tapping screws I would recomend this it is much eaiser. I guess they are removable but I Havent ever removed them.
A Harlely rake is the ultimate tool for lawn installation, It it takes the crappy fill dirt and makes a perfect seed bed. If you do a search, there are a few pics on here of what they can do.
I will have a few pics of a couple lawns that we mowed today up tomorrow.
