Abstract
A control system for a work machine, having an articulated joint and a work implement with at least one axis of rotation, has a first lever with a first longitudinal axis. A twist angle of the first lever about the first longitudinal axis is related to an articulation speed of the work machine. The control system also has a second lever having a second longitudinal axis. A twist angle of the second lever about the second longitudinal axis is related to a rotation speed of the work implement about the at least one axis of rotation. A plurality of operator control devices are disposed on the first and second levers.
