ABSTRACT:
This invention provides a three-function control mechanism that employs a single control lever for controlling a first, a second and a third actuator and which may be used in connection with a bulldozer. The control mechanism includes a control bracket, a control lever, and first, second, third, and fourth bellcranks supported by the control bracket. The control mechanism further includes first, second, and third linkage that interconnect the control lever, through the bellcranks, to respective ones of the first, second, and third actuators. Due to the supporting arrangement of the control lever, bellcranks, and linkage, the control lever may be moved forward or backward, twisted clockwise or counterclockwise, or moved side to side either separately or in unison. In doing so the control lever thereby respectively actuates the first, second, and third actuators.
