In my part of the country your grandfather would have been called a "cotton planter". A cotton farmer couldn't afford any of that stuff.
I appreciate your post and understand what you're saying but my Grandfather was in the field everyday; dawn to dusk. He and his hoe would walk the fields alone if needed. I have fond memories of working for him in the fields as a youth during the long hot summers while school was out. He also hated to see the mechanical Cotton Strippers come in as he thought it left too much cotton the field (which they did) but at the time cotton pickers would eventually become too scarce to find. He made a good living as such for many years; eventually retiring from farming altogether. He was an honest man making a hard honest living. Thanks to all like him. God Bless.
