Patent number: 10440877Abstract: An agricultural tillage system including a carriage frame assembly, a plurality of tillage elements coupled to the carriage frame assembly, an actuator and a residue reactive system. The actuator is moveably coupled to the tillage elements, and is directly in control of a soil contact depth of the tillage elements. The residue reactive system is in controlling communication with the at least one actuator. The residue reactive system reduces the soil contact depth of the tillage elements when the residue mass on the soil is reduced and/or the slope of the soil is above a predetermined value.Type: GrantFiled: August 18, 2016Date of Patent: October 15, 2019Assignee: CNH Industrial America LLCInventor: Robert A. Zemenchik

Patent number: 10420272Abstract: A system for monitoring the condition of a seedbed within a field may include an implement having a plurality of ground-engaging tools supported by the frame, with the implement being configured to create or be traversed across a seedbed extending downwardly within the field from an outer seedbed surface to a seedbed floor. The system may also include an auxiliary support arm coupled to a portion of the frame at or adjacent to the aft end of the frame. In addition, the system may include a seedbed floor detection assembly coupled to the auxiliary support arm that is configured to detect variations in a profile of the seedbed floor. Moreover, the system may include a seedbed surface detection assembly coupled to the auxiliary support arm that is configured to detect variations in a profile of the outer seedbed surface.Type: GrantFiled: March 31, 2017Date of Patent: September 24, 2019Assignee: CNH Industrial America LLCInventor: Michael G. Kovach

Patent number: 10337165Abstract: An industrial machine and methods for providing automatic tilt control for the same. One method includes determining a current tooth vector of a tooth included on a bucket of the industrial machine and a current path vector of the tooth and determining a current digging angle between the current tooth vector and the current path vector. The method also includes determining a delta angle based on the current digging angle and a target angle and automatically adjusting a tilt of the bucket based on the delta angle.Type: GrantFiled: April 13, 2017Date of Patent: July 2, 2019Assignee: Joy Global Surface Mining IncInventors: Anab Akanda, James Myron Maki

Patent number: 10306829Abstract: A ground height gauge assembly is provided. The ground height gauge assembly includes a shaft configured to be rotatably coupled to the header. The ground height gauge assembly includes a first arm coupled to the shaft and configured to simultaneously rotate with the shaft, the first arm defining a first length. The ground height gauge assembly includes a second arm pivotally coupled to the shaft and defining a second length, the second arm configured to be mounted in a first position and a second position. The second length of the second arm is dimensioned greater than the first length of the first arm. In the first position the second arm is configured to rotate independently of the first arm. In the second position the second arm is configured to be coupled to the first arm such that rotation of the first arm simultaneously rotates the second arm.Type: GrantFiled: February 10, 2017Date of Patent: June 4, 2019Assignee: CNH Industrial America LLCInventors: Jeffrey B. Fay, II, Terry S. Moyer, Zachary Stephens

Patent number: 10015921Abstract: A vertical tilling implement to be pulled behind and agricultural vehicle having a number of gangs of fluted-concave disc blades, rolling baskets, and wheels connected to a main frame. As the vertical tilling implement is pulled, the fluted-concave disc blades move the soil in a direction lateral to the side of the blades as well as up. Meanwhile, the rolling bars aid in leveling the seedbed and crushing the remaining large pieces of soil. The vertical tilling implement reduces the amount of subsoil compaction and cuts through heavy residue making it ideal for use in the fall or in the spring.Type: GrantFiled: April 13, 2015Date of Patent: July 10, 2018Assignee: CNH Industrial America LLCInventors: Michael George Kovach, Tracey Duane Meiners, Dean Alan Knobloch, Gaylen James Kromminga, Gregory S.

Patent number: 9986674Abstract: An agricultural tillage implement has a main frame section, a left wing section, and a right wing section. Lift wheels and gauge wheels are actuated by hydraulic cylinders supplied by a hydraulic system. Solenoid valves connect groups of hydraulic cylinders to each other and to bypass circuits. The solenoid valves and the bypass circuits function to selectively allow coordinated control and individual control of the lift wheels and gauge wheels. The hydraulic system has at least one hydraulic flow divider and combiner dividing hydraulic flow and pressure between at least one left hydraulic circuit and at least one right hydraulic circuit. The at least one hydraulic flow divider and combiner functions to coordinate the motion of the left rear lift wheels and gauge wheels, and the right rear lift wheels and gauge wheels, and may be overridden by bypass valves.Type: GrantFiled: March 31, 2016Date of Patent: June 5, 2018Assignee: CNH Industrial America LLCInventors: Matthew R. Sudbrink, Kena Shah, Dean A. Knobloch, James W. Henry

Patent number: 9968030Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.Type: GrantFiled: June 22, 2010Date of Patent: May 15, 2018Assignee: CNH Industrial Canada, Ltd.Inventors: Trevor Kowalchuk, Robin B.
