  • Patent number: 6796762
    Abstract: A boom and linkage mechanism for a skid-steer loader includes a frame and a right and a left loader arms. An implement may be vertically pivotally mounted to the forward ends of the loader arms, and a pair of tilt actuators may be respectively connected between the forward ends and the implement. Right and left forward guide links are connected between the frame and the loader arms. Right and left rearward guide links are connected substantially proximate to a rear of the frame and the loader arms. The lower ends of the rear guide links may be substantially lower than the lower ends of the forward guide links. Right and left lift actuators may be connected between the frame and the loader arms. The right and left lift actuators may extend and retract to raise the right and left loader arms such that the implement moves between a fully lowered position and a fully raised position, and wherein the fully raised position is located substantially vertically above the fully lowered position.
