Abstract
A coulter assembly has a resilient spring tine that bears against the compression face of the angled coulter during field operations to remove dirt clumps that otherwise inhibit the furrow-forming action of the coulter. A special spring coil mounting of the tine provides a lively vibratory action as the tine encounters various impact loads from different directions during field operations, thus rendering the tine essentially self-cleaning insofar as trash accumulations are concerned. The angle of attack of the tine relative to the ground and the coulter can be readily adjusted without diminishing the vibratory action of the tine.
