  • Patent number: 10822026
    Abstract: A steering system includes a drag link having a first support bushing opposite a second support bushing, a first steering hydraulic cylinder operably connected to the drag link, a second steering hydraulic cylinder operably connected to the drag link, a first tie rod operably connected to the drag link, and a second tie rod operably connected to the drag link. Each of the first and second cylinders and first and second tie rods are arranged to apply a corresponding radial force that is distributed between the first and second support bushings. One or more of the first and second steering cylinders and/or the first and second tie rods is positioned relative to the drag link to minimize a net summation of the first and second cylinder radial forces and the first and second tie rod radial forces that are applied to the first and second support bushings.

  • Patent number: 9412083
    Abstract: A system includes an aggregation engine that initiates a first interface module in response to a first request from a first user that indicates a first type of project information. The aggregation engine also receives, via the first interface module, the first type of project information and stores the first type of project information in a memory. The system additionally includes a workflow engine that initiates one or more workflows that indicate certain project information requested by an external group. The workflow engine retrieves, from the memory and based upon the initiated one or more workflows, a first subset of the first type of project information and formats the first subset of project information according to the workflow. The system also includes an export engine that transmits the formatted first subset of project information to the external group according to the initiated one or more workflows.

  • Publication number: 20150310390
    Abstract: A system includes an aggregation engine that receives a build sheet entry from a user that includes a configuration item, a category, and a value. The system also includes a workflow engine that determines a first approver associated with the configuration item and a second approver associated with the category. The workflow engine transmits a first approval request to the first approver and a second approval request to the second approver. The workflow engine receives a first response that indicates that the first approver approved the build sheet entry and a second response that indicates that the second approver denied the build sheet entry. The workflow engine receives an updated build sheet entry from the user that includes the configuration item, the category, and an updated value. The workflow engine transmits an updated second approval request to the second approver and receives an updated second response that indicates that the second approver approved the updated build sheet entry.

  • Patent number: 7874222
    Abstract: A power take-off assembly for a work vehicle including an improved power take-off shaft for installation and removal. The power take off shaft is extended and a cut out section on the first end of the shaft is provided to engage an extended portion of a spring loaded mechanism. Once the cut out section securely fits over the extended portion, the spring loaded mechanism is prevented from axially moving in a rightward direction, thus enabling the spring to hold the gear collar in place to engage the high speed gear. The PTO stub shaft has an extended end with protruding shoulders which serve to capture the snap ring between the stub shaft and the output shaft so that when the stub is moved axially the shoulders will pull the snap ring into the groove on the output shaft which securely fastens the stub shaft. A cut-out section on the front end surface of the output shaft is also provided to allow clearance for the tool to squeeze the snap ring tabs during installation and removal.
