| Undercut your cut 3-4 tenths below designed final grade. The way we like to do it is to strip the topsoil without using a specific grade until we hit clay, spread that topsoil in shallow fill areas on the first cut, and then go back and cut our clay out 3-4 tenths below final grade and haul that clay to deep fill area. Often fill it to 2 tenths below final grade in the deep fill areas, and then sweep our topsoil from shallow cut areas to the clay that we moved to deep fill areas. We strip the topsoil like that in 5 pass sections, cut the clay out, and then move to the next section over in the cut and flip the topsoil from the new section to the section we just pulled the clay out of. Confusing but it makes sense once you get the hang of it. We’ve saved a lot of fields from being ruined around here by flipping topsoil, some of our lighter dirt around only has 4-6 tenths of topsoil on it. Also by using this method you can get around cutting out the topsoil in the fill areas, obviously if the money to waste is there it can be a good thing to do but your cost per acre is going to skyrocket, it’ll double your time out there doing the job. Most of the time there is enough topsoil to get around having to do that. | |
