2.The Standard Tandem (Dual) Pump System is Shown, there is a Single Pump System Option available. The Single Pump only supplies the Hydraulics for the Cutter Head Motor and the Tractor Hydraulic System is used to supply the Boom Cylinder movements. The Schematic is very much the same except the Cylinder Control Valve Hose connections are run to and from the tractor instead of the way they are shown in the Schematic on the next page. (See System Schematic drawings for Pump Repair Section)

3.The Control valve will bolt on the top of the High Frame on the right hand side. There is a tab welded to the Frame that has two holes in it, the Valve mount plate will bolt to this tab and the valve will bolt to mount plate (See Figure 6) The Valve in Figure 6 shows the Hoses and Control Cables already connected, this is for illustration only. The Control Cables and Hoses are connected after the Valve is bolted to the mount plate. Most of the Hoses shown in figure 6 are running from the Boom. These Hoses must be connected to the correct Port on the valve and to the correct side to operate correctly.
