Abstract: Motorized vehicles having hydraulic tools as attachments are well known. Examples includes road graders, excavators, snow ploughs (and nursery equipment such as tree spades, tree movers and tree handling equipment), tractors, front loaders, and skid steers. A single hydraulic tool may be controlled by a simple manually operated hydraulic control system if the operation of the hydraulic tool is not complex. The use of “Electric over Hydraulic control” is more commonly used for hydraulic attachments with more complex functionality. A typical electric over hydraulic control system uses a bundle of wires; in which each wire in the bundle is dedicated to a particular operational feature of the attachment. These wires are prone to failure as a result of the wear and tear they are exposed to during normal use of the equipment. This, in turn, has led to proposals for the use of a wireless control system.
