The single-acting tractor control unit is set to the "Lower" position – port
(801-1) is connected to the tank.
When actuating the "Swing out knife support" button, the 2/3 way
directional control valve (Y54) is energized.
The baled material loads the ROTOCUT knives hydraulic cylinders (336),
making volume flow flow into the tank from the ram spaces via the
energized 2/3 way valve (Y54), the unenergized 2/3 way valve (Y55) and
port (801-1).
