Publication number: 20240049645Abstract: A concave assembly for an agricultural combine harvester comprises a concave, a cover, and a cover actuator. The concave comprises a grate. The cover has an opened position uncovering at least a portion of the grate to allow crop flow through the at least the portion of the grate and a closed position covering the at least the portion of the grate to block crop flow through the at least the portion of the grate. The cover actuator comprises a four-bar linkage and moves the cover between the opened position and the closed position.Type: ApplicationFiled: August 11, 2022Publication date: February 15, 2024Inventors: GARRICK W. HERBST, MICHAL KOCIS, MARTIN KOLLAR, JESUS LANDINEZ

Patent number: 11091026Abstract: A work vehicle including a body, a cooling system with one or more coolers, and a fan disposed adjacent to the coolers. A louver system is disposed adjacently to an inlet of the vehicle body. The louver system includes a first actuator operatively connected to a first plurality of slats and a second actuator operatively connected to a second plurality of slats. A first sensor operatively connected to a first cooler is configured to identify a first temperature of the first cooler and to generate a signal responsive to the identified first temperature. A second sensor operatively connected to a second cooler is configured to identify a second temperature of the second cooler and to generate a signal responsive to the identified second temperature. A position of the first plurality and second plurality of slats is determined respectively by the first and second temperatures.Type: GrantFiled: April 25, 2019Date of Patent: August 17, 2021Assignee: DEERE & COMPANYInventors: Jeffery C. Mussack, Alan D. Sheidler, Garrick W. Herbst

Patent number: 11092065Abstract: An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.Type: GrantFiled: April 25, 2019Date of Patent: August 17, 2021Assignee: DEERE & COMPANYInventors: Alan D. Sheidler, Garrick W. Herbst, Todd E. Van Hal

Patent number: 8800538Abstract: A diesel fuel supply circuit comprises a diesel engine (100); a fuel cooler (104); a fuel tank (102), and a valve (114). The valve (114) is operable to move the fuel cooler (104) from (1) a position within the circuit in which it cools fuel leaving the diesel engine (100) and going to the fuel tank (102) to (2) a position in which it cools fuel leaving the fuel tank (102) and going to the diesel engine (100) and vice versa.Type: GrantFiled: April 25, 2012Date of Patent: August 12, 2014Assignee: Deere & CompanyInventors: Nathan R. Vandike, Michael W. Derew, Todd E. Van Hal, Garrick W. Herbst

Patent number: 7875093Abstract: An air filter arrangement for an agricultural combine located on a panel at a side wall of the agricultural combine. The air filter arrangement includes a rotary filter mounted for rotation at a first aperture, a scoop enclosing the rotary filter and blocking substantially all air flow to the rotary filter except at a scoop inlet disposed along an upper edge of the scoop above the rotary filter, and at least one stationary filter disposed to filter air passing through a second aperture in the panel, the stationary filter being located between an upper portion of the rotary filter and the scoop inlet.Type: GrantFiled: May 7, 2010Date of Patent: January 25, 2011Assignee: Deere & CompanyInventors: James Monroe Hershbarger, Paul I. Craig, Todd E. Van Hal, Nathan R. Vandike, Nathan Ogden, Garrick W. Herbst

Patent number: 6691861Abstract: A discharge chute for the unloading auger of a combine is provided with a discharge opening which provides maximum discharge flow rate and maximum clearance for moving and positioning of the auger. The discharge chute has an upper surface extending downwardly at a first angle relative to a horizontal plane, and a lower surface extending downwardly in a second angle relative to a horizontal plane. The first angle of the upper surface is greater than the second angle of the lower surface. The discharge chute also includes an internally mounted dribble door pivotal between raised and lowered positions. The door prevents grain dribble when in the upper position, and allows unobstructed grain discharge when in the lowered position.Type: GrantFiled: October 25, 2001Date of Patent: February 17, 2004Assignee: Deere & CompanyInventors: Mark J. Reimer, Mark C. DePoorter, Garrick W. Herbst, Edwin M. Gerber, Lawrence P. Begyn
