Rear blades for utility tractors serve two primary purposes -- cutting angles such as ditches into the ground and, more commonly, leveling soil. Rear blades hook up to a three-point hitch on the back of a tractor, operated by a dual selective control valve (DSCV) that dictates the pitch and a three-point hitch lever that dictates the depth.
Raise the rear blade off the ground by pulling back on the three-point hitch lever located beside the seat on the right side. Lower the blade by pushing forward on the lever.
Push the DSCV to the right to pitch the rear blade to the right. Pull the DSCV to the left to pitch the blade to the left. (The DSCV is located on the right side of the platform between the seat and steering wheel.)
Drive the tractor to the site where you plan to operate it. Using the DSCV and the three-point hitch lever, adjust the blade until you achieve the desired angle.
Put tractor in a lower gear, keeping the speed between 2 and 4 miles per hour.
