  • Patent number: 10801178
    Abstract: 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.

  • Patent number: 9988786
    Abstract: 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.

  • Patent number: 9719228
    Abstract: A work vehicle may include a chassis, linkage, and locking pin. The linkage may include an upper link pivotally connected to the chassis, lower link pivotally connected to the chassis, and boom. The boom may include an upper arm pivotally connected to the upper link, lower arm pivotally connected to the lower link, front arm pivotally connected to a work tool assembly, and locking tab affixed to one of the front arm and the lower arm and protruding from one of the front arm and the lower arm in a direction away from the work tool assembly. The locking pin may be connected to the chassis and extend laterally relative to the chassis from a retracted position outside a travel path of the locking tab to an extended position intersecting the travel path of the locking tab.
