Brian: This time I will give you a few examples. 1. Two brothers farming 5,000 acres corn beans and winter wheat, 2-300 hp Deeres, 3 tractors I would judge 100 hp average each, 9600 Deere combine and small Gleaner. They farm over 45 miles of road. Their grain wagons are all highway dump trailers. They use a train tow dolly with air brake on one of the Deeres for pulling these. Beyond 5 miles from home base they hire highway tractors to pull these to elevator. My judgement I call their tractor and Combine hp 1,200 and on the 5,000 acres are very close to the 1/4 hp per acre.2. Father and son 2,500 acres cash crop and beef, slightly over 900 hp so they are just over 1/3 hp per acre 3. 800 acres cash crop and hogs 300 hp plus custom hires combine, again close to 1/3 plus the combine. 4. Had an uncle in the 1950s farmed about 100 acres 20 dairy cows, did all his work with a Super A. I measure that one at 1/5 hp per acre. 5. My dad farmed 200 acres and 40 dairy cows in 1950s with Farmalls 300 and 130. Close to 1/4 hp per acre. So you see progress has been great. I can not think of anyone today doing better than 1/4 hp per acre. In the mid 1950s a Ford or Chevy sedan would give you 25 miles per Canadian Gallon, today sedans about the same size with all the computer efficiency bells and whistles will give 25 miles per Canadian Gallon. That should come out to 20 miles per US gallon. I guess it just takes more horse power to be efficient.
