Much like its little brother, The Rhino Heavy-Duty Box Blade comes standard with CAT 1 hitching, a 21 ½” box depth and a cutting edge of ½” x 6” -- however these bigger units have a cutting width of up to 96”. That extra power has to come from somewhere -- these blades require at least 65 horsepower from a two-wheel drive tractor and 55 horsepower from a four-wheel drive.
