They are worth every penny IMO, we have them on 4 combines with 40ft headers and they work great. They will spread 50ft on a windless day, the 70 series regular tailboard is wider than the 60 series and is capable of spreading 35ft. At night when your throwing the straw into the standing crop you can just turn it down so you don't have header trouble on the next pass. I would actually like to see some facts on how much HP they take. You only have to pay that 5gs once, cause if you trade it off the next combine will be ordered with it.
