Isn't anyone aware that some animals will duck UNDER a fence? They don't all jump over. I came from Ohio to make hay in Montana one summer and antelope (or something) were usually watching us at a distance. Any move to get close and they ran directly at fences and in flash they magically appeared on the other side but were not juming over. It was a mystery till I was told they fold their legs and slide under the fence. The ranchers set the bottom wire at a certain height above ground so the animals can clear it. I don't know what the best height is but it shouldn't be hard to find it. I am a little surprised that this isn't better known by folks on a tractor forum. No cowhands here I'll guess.
