I fix and repair, and maintain what I can. Something on the farm is always needing attention.
Farmers have always been tool users, tool inventors all to save on back breaking labor. The first guy who ran Lockheed Skunkworks grew up on a Michigan farm. Many of our earlier inventors were farm boys but most Americans lived on farms back then.
How about the guy who invented how to make rolls of hay instead of baling it? I have no idea when that one came about. I see how farm tractors come with GPS and laser sighting these days. Its a bit humorous how advanced they have become. Of course the smaller simple tractors are still on the market too.
