What kind of acreage can one of those old combines cover if you have a clean crop of something like wheat or oats and get started by noon time after the dew has dried off. Could be getting 8 hours of cutting time on a good day. I know there are other variables but I'm just looking for a ball park idea. AC must have promoted covering a certain amount of acres as a sales pitch. I see guys wanting small combines for 40-50 acres and they never think about something like a 66 or newer type of model that they could get for almost nothing compared to a self propelled unit. I'm thinking on a good day maybe one could do 10 acres.
