I could be too but I am bigger (size of equipment wise) than they are. I have to say that 95% of the time when I'm driving to and from fields in one of the tractors, I am armerd I usually have my Mini14 Ranch rifle behind the seat and often am carrying a 45 automatic as well.
I have put a few in the ditch before, always someone in a big hurry to get nowhere and usually under the age of 40.
Lots of times I'm pulling an implement wider than a normal travel lane and they cannot wait a few seconds for me to find a wide spot to pull off and let them by. Last spring I put some kid in the ditch, big hurry to go nowhere. He tried to get around my planter, didn't make it, went in the ditch. I stopped, got out on the step. looked back at him cussing me out and got back in a drove away. I did call the State Police and tell them there was some young punk in the ditch at a certain address.
When I came back that way, he and his car were gone.
Most farmers I know when yield when they have room to.
What I find interesting though is how fast people drive on dirt roads. Guess they don't care about the sandblasting their vehicle chassis is getting and how that dirt is getting inside all the suspension joints. I'd never buy a used vehicle from anyone out here, thay are all junk.
