Abstract: A control lever (16) for effecting positional control of a work implement (18). An actuator means (60) applies a force to the control lever (16) in response to a sensed load being applied to the work implement (18). The force applied to the implement control lever (16) is in proportion to the load being applied to the work implement (18), thereby giving the operator a feel for the load being applied to the implement (18).
