Patent number: 11224153Abstract: Agricultural planting implements, as well as other ground-engaging implements, can utilize supplemental force assemblies to provide up and/or down force at the row or rows of the implements. The force can be used to overcome changing field conditions, obstructions, as well as changing particulate amounts and weights carried by the rows of the implements, and the implement itself. The up force can be set at system pressure, or can include control valves at each of the row units to control the amount of up force provided. The down force can be controlled by control valves at each of the row units, and can be used to overcome the up pressure or provide a designated amount of down force to the row.Type: GrantFiled: July 27, 2018Date of Patent: January 18, 2022Assignee: Kinze Manufacturing, Inc.Inventors: Scott W. Leimkuehler, Steve Nolte, Robert Blackwell, Matthew Wilhelmi, David Schulte, Paul Zinnel

Patent number: 11140812Abstract: A downforce system adjusts the amount of downforce being applied to a row unit of an agricultural implement. The downforce system is controlled to increase or decrease the force on the row unit. A load is sensed at the row unit and compared to either or both of a user defined target and a lower threshold that can be based, at least in part, upon a percentage of a value. When the load is determined to be below the lower threshold, the user defined amount is increased at a rate of change until the load is above the threshold, at which point the increase is stopped, and reduced, if necessary.Type: GrantFiled: December 13, 2018Date of Patent: October 12, 2021Assignee: Kinze Manufacturing, Inc.Inventors: Scott W.

Patent number: 9888624Abstract: An agricultural planter has a chassis with a tool bar and at least one row unit. Each row unit is carried by the tool bar and has a fluid actuator and a linkage assembly connecting it to the tool bar. The linkage assembly and fluid actuator allows the row unit to be raised and lowered. A control module is operable to individually raise and lower each row unit on the agricultural planter using the fluid actuator in response to either a manual input, an automatically determined requirement or condition of the at least one row unit, or an automatically determined operating condition of the agricultural planter. The control module is further operable to prevent the raising or lowering of an individual row unit on the agricultural planter based on either a configuration of the agricultural planter or the potential occurrence of an undesirable weight or drag distribution.Type: GrantFiled: June 30, 2015Date of Patent: February 13, 2018Assignee: CNH Industrial America LLCInventors: Alihaider Maniar, Marvin A.

Patent number: 9470298Abstract: The straight tracking control system can use a control method to achieve a desired straight motion of a machine with a dual path electronically controlled hydrostatic transmission. In the control method, the first drive system, e.g., the left or right drive system, pump solenoid current can be modified based on first and second drive system velocity feedback when the machine is commanded to move in a straight line path in the forward or reverse direction. A memory latching concept is used to latch the straight tracking factor at the initiation of and during the turn so the same straight tracking factor is used throughout the turn. The straight tracking factor is unlatched at the completion of a turn after a specific time delay and a new straight tracking factor can be calculated. The straight tracking method also utilizes transmission fluid temperature and utilizes additional fluid reserve in order to maintain straight machine movement.Type: GrantFiled: October 29, 2013Date of Patent: October 18, 2016Assignee: CNH Industrial America LLCInventors: Kushan Vora, Navneet Gulati, David Schulte, Joseph R.
