DEPTH CONTROL AND PROTECTIVE APPARATUS FOR TILLAGE ASSEMBLY Abstract of the Disclosure A depth control and protective apparatus is disclosed as particularly useful in a tillage assembly for sod seeding pur- poses. The apparatus includes a pair of skids mounted upon a pivoted arm, which arm has also mounted thereon a pair of cutter wheels for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for essentially vertical movement with respect to the associated arm and cutter wheel mounted thereon to thereby determine and control the depth of furrow cut by the associated cutter wheel. A substantially circular plate has an oval aperture in the cen- tral portion through which the axle and drive for the cutter wheel extends, and an inwardly directed cylindrical flange ex- tends to the periphery of the circular plate to protect the axle and to provide for movement of the skid relative to the cutter wheel and axle. A seed boot is fastened to the skid rearwardly of the cutter wheel by an ear extending above ground level be- tween the cylindrical flange of the skid and the seed tube at a point spaced from the lower end thereof. Thus, regardless of the selected depth of the furrow cut, the tube remains in the same position relative to the ground.
