Calf Catcher works great! I hooked it up to my ATV. It probably would work on UTV cuz the arms are adjustable for hookups. Has a box that goes with. It's for the calf to go in so the mother cows to follow. Has springs by the tire so it's not so rough. I used it all the time either to tag calves or to move them to other areas. Cheap insurance for not getting hurt or injured while you go through calving season. $400. Lisbon ND
