Abstract
A method of automatically setting an auxiliary hydraulic valve's flow rate and returning to that flow rate automatically is disclosed. The work vehicle such as a backhoe has two hand controls, one of which has a button, and the other has a thumb wheel. To set the hydraulic flow rate, one both presses the button one hand control and moves the thumb wheel on the other hand control until the proper flow rate is reached. At this point, both button and thumb wheel are released. This causes the flow rate to be saved in RAM or ROM memory. The flow rate can be varied at any time by rolling the thumb wheel up or down. One can return to the previously save flow rate by pressing the button. Both controls are preferably spring loaded.
