    摘要： An agricultural implement includes a chassis; an implement frame carried by the chassis; a shank connected to the implement frame, the shank including a shank point configured to break apart soil and a load sensor associated with the shank point which is configured to output shank load signals as the shank point advances through soil; an actuator carried by the chassis and configured to adjust a depth of the shank point; and a controller electrically coupled to the load sensor and the actuator. The controller is configured to receive the shank load signals; generate a load profile from the received shank load signals; analyze the load profile to determine whether the shank point is in a soil compaction layer; and activate the actuator to adjust the depth of the shank point based on the analyzed load profile.

    摘要： 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.

    摘要： An apparatus for maintaining a tillage implement such as a plow at a consistent working depth utilizes a spring biased quadrilateral linkage to maintain the tillage implement in a position having to float forwardly and upwardly from the working depth thereby preventing unwanted flotation of the tillage implement from the working depth until the tillage implement encounters a substantially vertical load.
