The present invention is a control system for conditioning movement of a work implement during a work cycle. In one embodiment, the control system comprises an electronic-hydraulic valve connected to the work implement and a computer system having a central processing unit and a memory device. The control system further comprises a mode control module stored on the memory device. The mode control module is generally adapted to detect whether the control handle of the work implement is signaling for operating in a smooth mode or an abrupt mode, and to output a control signal to the electronic-hydraulic valve to control operation of the work implement during the smooth mode or the abrupt mode. The mode control module comprises a smooth mode module and an abrupt mode module. The smooth mode module and the abrupt mode module are adapted to optimize movement of the work cycle during the smooth mode, and abrupt mode, respectively.

The control system of claim 1 wherein said control system includes a central processing unit for controlling the operation of said electronic controlled hydraulic valves.3. The control system of claim 1 wherein said electronic controlled hydraulic valve includes a memory device.4. The control system of claim 1 further including an activation device that determines said mode of operation by coupling the speed of movement and number of activations thereof to said control module.5. The control system of claim 1, wherein said mode control module includes a smooth mode module and an abrupt mode module.6. The control system of claim 5, wherein said smooth mode module and said abrupt mode module condition movement of the bucket according to a control curve having spool displacement versus said activation device displacement.7. The control system of claim 5, wherein said abrupt mode module is enabled for a pre-determined period of time.8. A method for conditioning movement of a bucket having an electronic controlled hydraulic valve coupled thereto for controlling the movement of said work implement in response to an operator generated activating signal from an implement controller during a work cycle, the method comprising the steps of: (a) automatically operating said bucket in a one of a smooth mode and an abrupt mode; and(b) outputting a control signal to said electronic hydraulic valve to control operation of said bucket during one of said smooth mode and said abrupt mode.9. The method of claim 8, further including the step of disenabling said abrupt work mode after a pre-determined period of time.10. The method of claim 8 wherein said operator generated activating signal is generated by an operator's movement of a joy stick controller.11. The control system of claim 1, wherein operation of the bucket in said abrupt mode controls movement of the bucket to perform a shakeout operation.
