Abstract
Abstract A seed planting apparatus consisting of a first section with one or more similar sections attached thereto. Each section has furrowing means, seed dropping means and press wheels. Optionally, tanks for holding water or liquid fertilizer are mounted on each section with pipes running to the rear of each furrowing means. Each section is supported on aster wheels at its front corners and centrally of its rear edge to form a generally triangular suspension. The wheels supporting the rear of the first section can be swiveled from a position for travel in one direction to a position for travel at 90* thereto with the wheels being releasably locked in each of the two positions. In the field, all sections in side by side relation are towed from a hitch on the first section. In transport position, all sections are towed in an end to end relationship by a hitch attached to the end of the side sections. In transport position, all of the caster wheels swivel freely except the rear set on the first section. In the field position, all of the rear wheels are releasably locked to keep them from swiveling about their caster axis while all of the forward wheels are permitted to swivel.
