ABSTRACT:
A single handle control mechanism has two shafts for connection to two independently operable mechanisms, such as hydraulic valves controlling the position of hydraulic actuators in an agricultural tractor. The shafts are operable to rotate selectively either individually or in combination about a common longitudinal axis of rotation through manipulation of a handle member which is rotatable about two orthogonal axes oriented perpendicularly to the axis of rotation of the shafts. The handle member has a first roller and slot coupling for effecting the rotation of the shafts and a second roller and slot coupling for effecting the rotation of the other coaxial shaft. The slots of the first and second couplings are orthogonal to one another to resolve the rotation of the handle member into a first component for rotating the first shaft and a second component for rotating the second shaft.
