When one of the design parameters is that the vehicle must be able to carry a round bale almost as big as the vehicle itself, you know it’s going to be one tough, hard working UTV. Arctic Cat’s new Prowler HDX 700 can carry the bale, 3 passengers, and with a dump box seemingly half as big as a football field, practically the whole barn! We spent several days and 400 miles picking our way through the rocks, canyons, and desert to the North Rim of the Grand Canyon and back, and the HDX 700 was as reliable as a trusty dog or sure footed horse. Driving the HDX is much more comfortable, though.
