Abstract: A header including a cutter bar configured to cut crop for harvesting and a header frame supporting the cutter bar. A transport assembly is operatively connected to the header frame. A support arm is rotatably coupled to an axle of the transport assembly and is pivotably coupled to a mounting frame coupled to the header frame. A cam linkage is disposed at the support arm to provide a mechanical advantage for an operator when moving the transport assembly from a transport position to a harvest position. The cam linkage includes a lift assist device having a first end connected to the mounting frame and a second end coupled to a cam arm. Extension of the second end from the first end of the lift assist device applies the cam arm to a cam surface of the support arm to move the transport assembly to the harvest position.
