ABSTRACT:
The invention is directed to a trash seeder having a seeding tyne and a following press wheel. A hydraulic cylinder applies pressure to both the seeding tyne and the press wheel. The press wheel is pivoted to the frame by a trailing arm and the tyne is pivoted to the trailing arm, the hydraulic cylinder acting on the tyne. Thus the single hydraulic cylinder applies pressure to both tyne and wheel, while allowing the tyne to move upwardly over obstructions without effecting operation of the press wheel.
