I don't just have the image of a tractor for the more "modern" farmer. I have pre-tractor images of a farmer and plough with horses, and a farmer with plough and oxen. I also have a sheep image, which could be used for a sheep farmer, a steer, for cattle farming, and Joelle's page has a cow for dairy farming, Natalie's page has a barn for generic farmer, and so on. (Both Joelle's page and Natalie's page are linked from the top of mine.)
