We have budgeted about $250K per year for FDR. We are very satisfied with the Road Hog. It is easy to control mounted directly to the arms of the loader. We have been using between 6 and 8 teeth per day for a 8 hour shift. We grind a average depth of about 9-inches deep. If we use cement we grind 12-inches deep and add 1% cement by volume. We normally pave back one 3-inch lift of HMAC. In some areas we pave two 2-inch lifts with a layer of paving fabric in between the two lifts. All the spots we did last year are holding up pretty well.
