Same problem here, it's a mess can't get off the farm roads or right on the tops of the hills or you'll go on an unwanted ride to the bottom of the hill. Cows are calving now, and have to walk to them to check on and tag the calf, sure no driving to them. Our houses and barns are all close on the top of a hill, ( we have to utilize what little level land we have for buildings). The back yard is more or less the barn fronts, and that area is just soupy mud where I have kept a few rolls of hay for easy access, and the tractors have run.
