Abstract: Linkage assemblies for harrow implements are provided that facilitate the consistent positioning of all teeth of the harrow implements in an appropriate orientation (i.e., the appropriate attack angle) during operation. Beneficially, due to the configuration of the linkage assemblies within the harrow implements, the linkage assemblies are configured to be maintained in a generally horizontal orientation during operation. As such, each of the linking elements of the linkage assemblies will have their orientations aligned, such that a horizontal plane will encompass all of the linking elements of a given harrow implement. This allows for all of the teeth of the harrow implement to be positioned at the desired and appropriate orientation.

Abstract: An implement for tilling the soil and methods of using the same. The implement may include cultivator sweeps arranged in staggered rows, trailing coulters positioned behind a rearmost row of the cultivator sweeps, and a finishing attachment positioned proximate the trailing coulters. The trailing coulters are designed to penetrate deeper into the soil than the cultivator sweeps. The method includes passing such an implement through the soil such that the trailing coulters pass through the soil after the sweeps and the finishing attachment passes over and/or through the soil.
