Patent number: 12349614Abstract: A yaw rate is sensed on a towing vehicle that is towing an air seeder. The sensed yaw rate is used to predict a future yaw rate on a planting implement of the air seeder. An application rate of material is varied across the application implement based upon the predicted yaw rate across the implement.Type: GrantFiled: November 10, 2021Date of Patent: July 8, 2025Assignee: Deere & CompanyInventors: William D. Graham, Robert T. Casper, Ray M. Scheufler

Patent number: 12284934Abstract: An information map is obtained by an agricultural system. The information map maps values of a characteristic at different geographic locations in a worksite. An in-situ sensor detects tractive characteristic values as a mobile agricultural machine operates at the worksite. A predictive map generator generates a predictive map that maps predictive tractive characteristic values at different geographic locations in the worksite based on a relationship between values of the characteristic in the information map and tractive characteristic values detected by the in-situ sensor. The predictive map can be output and used in automated machine control.Type: GrantFiled: April 8, 2022Date of Patent: April 29, 2025Assignee: Deere & CompanyInventors: Nathan R. Vandike, William D. Graham, Cary S. Hubner, Andrew J. Peterson, Benjamin M. Lovett, Darin L. Roth, Martin Unterpaintner

Publication number: 20230309437Abstract: One or more information maps are obtained by an agricultural system. The one or more information maps map one or more characteristic values at different geographic locations in a worksite. An in-situ sensor detects a soil property value as a ground engaging machine operates at the worksite. A predictive map generator generates a predictive map that predicts a predictive soil property value at different geographic locations in the worksite based on a relationship between the values in the one or more information maps and the soil property value detected by the in-situ sensor. The predictive map can be output and used in automated ground engaging machine control.Type: ApplicationFiled: March 31, 2023Publication date: October 5, 2023Inventors: Bhanu Kiran Reddy PALLA, Andrew J.

Patent number: 11343959Abstract: An air distribution system for a seed cart provides for improved air flow distribution upon identification of a turning event. The seed cart may have a fan operable to create an air stream. A set of primary tubes coupled to the fan may receive separate portions of the air stream from the fan. A distribution manifold may have a first plurality of passages therethrough and a second plurality of passages therethrough. A restrictor assembly may comprise a first end, a second end oppositely disposed from the first end, and a plurality of inlets and a plurality of outlets disposed therebetween. The restrictor assembly may have a plurality of restriction components. Restriction of air flow proximate the first end is different than the restriction of air flow proximate the second end.Type: GrantFiled: October 31, 2019Date of Patent: May 31, 2022Assignee: Deere & CompanyInventor: William D.

Patent number: 11014741Abstract: A closure assembly is disclosed for a work machine having a supply tank with a tank opening. The closure assembly has a lid and lift, actuator and latch mechanisms. When the closure assembly is attached to the tank, the lift mechanism is configured to support the lid off of the tank opening. The actuator mechanism mounts to the lid to move the lid with respect to the tank opening between first and second positions in which in the first position the lid overlies the tank opening and in the second position the lid is substantially clear of the tank opening. The latch mechanism may be moved into a latched orientation in which when the lid is in the first position the latch mechanism latches the lid into engagement with the tank opening.Type: GrantFiled: February 29, 2016Date of Patent: May 25, 2021Assignee: DEERE & COMPANYInventors: Stanley R.
