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: A tillage implement comprising a main frame, a front group of coulter blades carried by the main frame and extending generally laterally, and a rear group of coulter blades carried by the main frame and extending generally laterally. The tillage implement additionally comprises a set of wheels configured to support the main frame and positioned generally between the front and rear groups of coulter blades. The tillage implement additionally comprises a group of harrow assemblies carried by the main frame and positioned rearward of the rear group of coulter blades. The tillage implement additionally comprises a front group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the group of harrow assemblies. Furthermore, the tillage implement comprises a rear group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the front group of finishing reels.

Abstract: A tillage implement has a main frame provided with power-actuated lift wheels at the rear of the frame and a pair of gauge wheels at the front of the frame. A linkage system connecting the rear wheels with the front wheels transmits the raising and lowering motion of the rear wheels to the front wheels so that the main frame remains level as it is raised and lowered by all of the wheels in unison. However, a coupling that uses an equalizing rocker bar between front and rear linkages of the linkage system permits either of the front wheels to be raised or lowered in a non-corresponding manner relative to the other front wheel as differences in terrain contour are experienced between the two front wheels. During such non-corresponding shifting of the front wheels relative to one another, movement of the two front wheels is in equal amounts but opposite directions to maintain both front wheels engaging the ground at all times and equally sharing the load.

Abstract: A tillage implement has a main frame provided with ground-engaging wheels that support the main frame at a selected height above the ground. Tillage shanks may be provided on the main frame and, if so, have their depth of penetration into the ground determined by the selected height of the main frame. Gangs of freely rotatable circular blades are carried on the main frame for both fore-and-aft angle adjustment relative to the main frame about respective upright pivot axes and up-and-down depth adjustment relative to the main frame about respective horizontal pivot axes. Such angle and/or depth adjustments can be carried out on-the-go from the tractor seat and without raising or lowering the main frame such that if tillage shanks are provided on the main frame, the working depth of the tillage shanks can remain unchanged as the gangs are adjusted.

Abstract: A tillage implement has gang assemblies of rotatable tillage tools that can be angle-adjusted from the seat of the towing tractor using hydraulic actuators. The tillage tools may comprise generally flat, wavy coulter blades or the like so that the machine may be set up for vertical tillage with the coulters aligned at a zero degree angle with the path of travel of the implement or for residue management operations with the coulters maintained at an oblique angle of up to ten degrees relative to the path of travel. A six degree angle is preferred for the residue management position. A master-slave hydraulic flow arrangement for the actuators assures simultaneous actuation, while mechanical synchronizing apparatus between the two front gang assemblies on the center frame section of the machine assures synchronized movement of those assemblies. Mechanical motion-transmitting mechanism transmits the hydraulically powered adjusting movement of the front gang assemblies to the rear gang assemblies.

Abstract: A tillage implement equipped with a finishing attachment for chopping and leveling soil. The implement includes at least one soil engaging element (e.g., a shank) operable to form a trench with mounds on either side of the trench. The finishing attachment includes at least one soil chopping and leveling assembly that is operable to chop up clods of soil and crop remnants in the mounds and to level off the mounds by pushing the mounds at least partially into the trench.
