(3) Return Spring
(4) PTO Brake Disc
When the PTO lever is set to "DISENGAGE" position, the oil passage is closed by the PTO control valve (14).
The piston (9) is pushed against the PTO brake plates (8) and PTO brake disc (4), which creates clearance between
the steel plates (10) and clutch discs (11), causing no friction. At the same time, the PTO brake disc (4) is held
between the PTO brake plates (8), causing friction. Therefore, the power to the implement is shut off and brake
engages to prevent the PTO shaft (5) from the free-spinning.
