I have had this idea in my head for the last year and over the winter decided to jump in and do it. I started topdressing last year with great results. The problem I had was getting materials from the trailer to the Turfco F15. I was using the old grain scoop method and by the end of the day my back would be killing me and 2 yards was enough for me. I decided to build a bin with a conveyor floor to move the materials into the topdresser. I also put in an agitator to break up clots and fluff the material. The bin holds almost 9 cy. The trailer has a 15600 capacity so I can carry about 10k lbs of material. I plan on adding the Eco Lawn spreader as well. There is room in front of the trailer to carry the Plugger 850 and the Eco Lawn. This should allow me to do 8-10 houses a day by myself without breaking my back. Here are some pics let me know what you think.
