light saddle horse trained to cut (isolate) livestock, especially cattle, from herds. Most are quarter horses, with the intelligence, speed, and ability to make quick starts, stops, and turns. A well-disposed and trained cutting horse can manoeuvre an animal away from a herd and into a corner with little direction from a rider, or, in some contests, without a rider.
