View Under the Cab (AA) Pressure tap. (8) Pressure reducing valve.The pump pressure oil (A) is reduced by pressure reducing valve (8). The pressure setting of the valve is adjustable. The pressure setting of the valve can be measured from pressure tap (AA) .In order to treat the stump, measuring and control system (7) sends a signal to solenoid valve (5). The solenoid valve moves to the left in order to allow pump pressure oil to flow to pump (1). Because the harvester head saw function is activated, the implement pump is stroked to maximum.

View in Front of the Cab (1) Stump treatment pump. (4) Tank for the stump treatment.The treatment in the pump is pumped through check valve (2) and out nozzle (3) in the saw bar bracket.After the coating has been sprayed, solenoid valve (5) moves back to the right. As the piston in pump (1) returns, more treatment is drawn from tank (4) through check valve (6).
