Operating laws When activating the PTO proportional to engine speed, the low pressure driving circuit sends oil into the clutch housing. The clutch spring, then the spring washer, are compressed by the piston and the friction disc are pushed
closer gradually to transmit torque. When the command is cancelled, pressure drops at 0 bar. Torque is no longer transmitted.
