Patent number: 10801178Abstract: A work machine comprising a frame and a ground-engaging mechanism, the ground-engaging mechanism configured to support the frame on a surface, a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to the frame and moveable relative to the frame by a pair of boom hydraulic cylinders, an attachment coupler coupled to a distal section of the boom arms, and an attachment. The attachment comprises a work tool. The work tool is coupled to the C-frame. A pair of first C-frame sections are pivotally coupled to the frame of the work machine, and a second C-frame section is pivotally coupled to the attachment coupler, wherein actuating the pair of boom hydraulic cylinders engages the boom arms, pitching the attachment upwards or downwards.Type: GrantFiled: December 7, 2018Date of Patent: October 13, 2020Assignee: Deere & CompanyInventors: Nilesh Kumbhar, Michael Tigges, Brett Graham, Jason Simmons, Nicholas Rokusek, Anil Sharma

Patent number: 9988786Abstract: A lift linkage assembly for a work machine having a work tool. The lift linkage assembly includes a frame, a boom arm, an upper link, a lower link, and a hydraulic actuator. The boom arm is configured to be pivotally coupled to the work tool and has a surface that defines a longitudinal axis. The upper link has a first end pivotally coupled to the frame and a second end pivotally coupled to the boom arm. The lower link has a first end pivotally coupled to the frame and a second end pivotally coupled to the boom arm. The hydraulic actuator has a rod that is pivotally coupled to the boom arm and moves between a retracted position and an extended position. The upper link, lower link, and hydraulic actuator are each spaced from the longitudinal axis.Type: GrantFiled: February 20, 2015Date of Patent: June 5, 2018Assignee: DEERE & COMPANYInventors: Kyle T. Martin, Travis Shekleton, Andrew W. Kahler, Jeff Ekins, Nilesh Kumbhar
