Abstract
A work machine having a first work member and a second work member, both operated from a pivotal control station. In a preferred embodiment the work machine has a backhoe assembly and a loader assembly both supported on a frame and operable from the pivotal control station. The work machine may have left and right low-profile drive systems that allow the first work member to perform work outside and parallel to the longitudinal center axis of the work machine. The work machine has a low-profile power source and operator platform that allow unobstructed visibility of the first and second work members from the control station.

34. An excavator comprising:
-
a frame comprising a first end and a second end;
a low-profile left drive system and a low-profile right drive system both supported by the frame for propelling the frame in a plurality of directions;
a first work member supported by the frame so that the first work member is operable at the first end of the frame, the first work member comprising;
a swing arm pivotally connected to the frame and having a central longitudinal axis;
a swing post pivotally connected to the swing arm;
a swing arm actuator fixed to the frame and adapted to pivot the swing arm and swing post relative to the frame to a plurality of positions, the plurality positions including at least one position placing the swing post beyond the left drive system and at least one position placing the swing post beyond the right drive system; and
a swing post actuator fixed to the swing arm and adapted to impart a pivot motion to the swing post relative to the swing arm to either side of the central longitudinal axis of the swing arm such that the pivot motion of the swing post is not restricted by the position of the swing arm; and
a second work member supported by the frame so that the second work member is operable at the second end of the frame. - View Dependent Claims (35, 36, 37, 38, 48)
