  • Implement frame convertible between field and transport positions
    Patent number: 10980165
    Abstract: An implement frame having a carriage frame for coupling to a towing vehicle and wheels to support the frame for movement over a ground surface. A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position.
    Type: Grant
    Filed: December 17, 2018
    Date of Patent: April 20, 2021
    Assignee: Deere & Company

A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position. All motion is accomplished through actuators, such as hydraulic cylinders, to automate the process making it quick and easy.
