IMPROVED CUTTER WHEEL FOR TILLAGE APPARATUS Abstract of the Disclosure An improved cutter wheel that is particularly useful with tilling apparatus for sod seeding purposes. The cutter wheel is mounted for rotation by a drive structure that includes a drive shaft. The cutter wheel includes a central disk portion with an outer periphery defining a plurality of equally spaced slots, each for receiving a tip-holding insert. A bullet-shaped tung- sten carbide tip is soldered or brazed to the tip-holder and the holder is welded to the disk. The disk periphery is shaped to allow cutting clearance for the tip, to protect the tip from breaking off, and to provide rear support for the tip-holder. The angle at which the tip is connected to the holder is chosen so that the brazed or soldered joint is loaded primarily in compression as the wheel cuts through the soil.
