An ergonomic hand control is disclosed. The hand control includes a joystick that is moveable along a plurality of axes and movement of the joystick along any of the axes transmits an electronic input signal to an electronic control computer for controlling a plurality of motor grader functions. A second end of the joystick includes a finger rest and a series of ledges that are separated from each other by a riser. Mounted on each ledge is a switch. Movement of the switches along any of a plurality of axes is used to control one of a number of motor grader functions through the electronic control computer. The design of the hand control permits an operator to properly position a hand on the hand control without requiring the operator to look at the hand control.
