Here in SE Iowa, I bid a 41 acre area at $700 and it was high. I think around here, 25-35/acre depending on obstacles works up to around the 5 acre size, but as the size increases, the $/acre bid needs to go down a bit, and in reality it should. One unload - mowers are running 100% of the time. I could have done quite alright on the 41 acre bid (Two of my mowers would have taken about 6 hrs.), but maybe the person that is now doing it does ok. This is a free market system. I have a nice clientel and am doing fine. Some day that 41 acre place may run out of bids lower than $700 and we will be doing it.
