The ST400i would be a welcome hand on just about any farm or ranch. We have cow/ calf pairs and unbred heifers on rotational grazing. And young bulls that have to be in their own pasture. The fence fixing, building, changing, and redoing never seems to end. But most of all the ST400i would help us most because sometimes the best help I have doesn't swing a big hammer and he can learn to do it smart instead of hard.
