I have an just over 1.5 acres that I need to grade, seed and straw, its all new topsoil that was brought in to satisfy local soil conservation agency so it will be fairly easy to work with. Problem is the site owner was getting hounded last year by soil conservation about erosion so he covered the entire site with straw only, question is do I need to get the old straw off before grading, or will the harley rake pulverize the old straw enough ? My plan was to use a landscape rake to scrape old crap away then a gill rake ( soil pulverizer) on a tractor. I have several years of exp using a tractor with a three pt hitch but only a few times using the harley? Sorry for the long winded description but one last question, can the old straw be used over ? (its been down since last fall). Owner wants to cut any corner he can. Imagine that. Any suggestions are greatly appreciated. Thanks.
