Definitions are everything here - what are considered "smaller farms?" - My cousin in Alberta, her husband, and two kids with occasional contract help farms two sections (1280 acres) of various crops - and his role in the harvest/planter (outside of parking, which is epic when he has a full set of fertilizing tanks connected) seems to be predominantly supervisory - GPS and software-defined systems do most of the actual work now. He even has a mini-fridge in his Air-Conditioned Cab. Would we consider that to be a smaller farm?
