Claim 0:
1. A handheld controller for operating a hydraulic system including a first, second, and third axis of operation, a battery with a battery output, and a direct current (DC) hydraulic pump, the handheld controller comprising:
a first joystick configured to control the battery output to the DC hydraulic pump, the first axis of operation of the hydraulic system, and the second axis of operation of the hydraulic system; and
a second joystick configured to control the battery output to the DC hydraulic pump and the third axis of operation of the hydraulic system,
wherein each joystick is positionable along two axes of movement, each axis corresponding to a maximum of one directional valve of the hydraulic system, each joystick biased to a central home position,
wherein a predetermined movement of either joystick activates the directional valve associated with that joystick,
wherein movement of either joystick further from the central home position beyond the predetermined movement increases the hydraulic pressure of the hydraulic system, and
wherein movement of a joystick from a resting position for a predetermined range about one axis will not vary the hydraulic pressure nor activate the associated directional valve.
