Abstract

The ridge preparation tool is adapted to be attached to a seed planter directly ahead of the trench-forming structure of the planter so as to skim off the crest of the ridge for the production of a clean, relatively narrow strip of prepared soil in which the trench-forming structure can operate effectively. The free-wheeling skimming disc of the tool is held at an oblique angle to the centerline of the planter and may be adjusted to increase or decrease the extent of side throw of the skimmed off materials by selectively raising or lowering an outwardly bent mounting arm that holds disc at its oblique angle. Raising or lowering the angled mounting arm causes the disc to cock inwardly or outwardly while maintaining the same oblique angle. The throw-adjusted disc can be returned to the same skimming depth by appropriate manipulation of a vertical adjustment unit associated with the tool.
