ABSTRACT:
A novel mechanism is presented that is able to harvest and load and to unload and install large rolls of sod with only one worker. It is equally useful with conventional sods grown on soil as well as sods grown over an impervious surface. The device is attached by a shiftable bracket to the utility mounting plate and hydraulics of a suitable tractor, skid steer loader, or modified fork lift. It consists of a steel spear or prong attached to a clevis that rotates slightly more than 180 degrees. Cones are placed on the hinged spear and these position PVC pipe or other tubing of the same length as the sod roll desired. The spear with cone(s) and tubing is placed at a right angle, either to the left or right, of the direction of the loader and dropped to the surface at the end of a cut sheet of sod. Small protrusions or prongs on the surface of the tubing lightly grasp the sod and begin rolling it up on the tubing. When the sod roll reaches the desired size, it is lifted, changed to a forward position, transported to, and loaded on a truck bed. At the laying site the process is reversed: the hinged spear is inserted into the tube, and the sod roll is lifted off the truck bed. It is carried to the laying site in the forward position where the sod roll is shifted 90 degrees forming a right angle to the loader, lift, or tractor. The sod roll is placed on the ground and carefully unrolled by the movement of the tractor and by the rotating tube and cone(s). The large roll of sod is thus installed by the careful work of one operator.
