(1) Oil supply for harvester head (2) Case drain line from harvester head (3) Case drain filter (4) Attachment valve for two pump flow (5) Main control valve (6) Attachment control valve (7) Line relief valve (8) Line relief valve (9) Solenoid valve (harvester head) (10) Pilot manifold (11) Left pump (12) Pilot pump (13) Right pump (14) Hydraulic TankThe harvester head is operated by push buttons on the joysticks that are located in the cab.Pilot pump (12) supplies oil to pilot manifold (10). When the hydraulic activation lever is moved to the UNLOCK position, pilot oil flows from pilot manifold (10) to solenoid valve (9). When the push buttons on the joysticks are activated, pilot oil flows to attachment control valve (6) and to the attachment valve for two pump flow (4). The pilot oil will shift the spool in of the valves to the downward position. This allows oil from right pump (13) to flow through attachment control valve (6). This also allows oil from left pump (11) to flow through the attachment valve for two pump flow (4). The hydraulic oil from the two pumps combines after the oil passes through both valves. The pump oil flows through oil supply for harvester head (1) to the harvester head. Return oil from the harvester head flows to hydraulic tank (14). The case drain flows through case drain lines from harvester head (2) through case drain filter (3) back to hydraulic tank (14) .Reference: Refer to the Owner's Manual and the System's Operation Manual of the harvester head for more information.
