RAS ATTACH AND PTO CIRCUITS The RAS attach and PTO circuits are controlled by two 3 position pilot valves. Pilot oil is delivered to the actuating ends of the relative valve bank working section and operates the main valve bank spool. This spool diverts main hydraulic pump flow into the RAS lines and the system develops pressure to actuate the cylinders. The RAS attach control engages the RAS lock tongue and disengages the tongue when the implement release valve is operated. The RAS attach lines are coupled to the RAS lock tongue manifold (located on the RAS lift plate) via quick connect couplings. Once the tongue is engaged these lines are removed and can be used as a second PTO set or connected to the dummy couplings for easy storage. The PTO circuit operates in the same manner as the RAS attach circuit.
