(6) Centershift lock switchCentershift lock switch (6) is located on the console to the right of the operator's seat. The position of the centershift lock switch (6) controls the solenoid valve (2) . The solenoid valve (2) is used to engage centershift lock cylinder (5) . The solenoid valve (2) is used to disengage centershift lock cylinder (5) . When centershift lock switch (6) is moved to the DISENGAGED position, solenoid valve (2) redirects the power train oil from the transmission filter in order to disengage the centershift lock pin. When the centershift lock pin is disengaged, the disengaged light on the instrument panel will come on.When centershift lock switch (6) is moved to the ENGAGED position, solenoid valve (2) allows the power train oil from the transmission filter to engage the centershift lock pin. The machine is normally operated with the centershift lock pin in the LOCK position. Since the centershift lock pin cannot be seen by the operator, centershift indicator (3) shows the operator when the centershift lock pin is in alignment with the correct hole in arm assembly (4) . Centershift indicator (3) is located on the rear of the link bar.The power train oil flows from the transmission filter to centershift lock cylinder (5) . In the LOCK position, the power train oil flows through centershift lock cylinder (5) . This holds the centershift lock pin in the LOCK position.
Personal injury could result from the sudden movement of the blade when the centershift lockpin is released.Before releasing the centershift lockpin be sure that all personnel are clear of the blade area, the circle and blade are centered under the machine and the blade has been lowered to the ground.
In order to move arm assembly (4) and the circle to another location, push the latch tab forward and move centershift lock switch (6) to the DISENGAGE position. This will send a signal to solenoid valve (2) . The centershift lock pin will pull out of arm assembly (4) . The centershift cylinder and the lift cylinders are then operated in order to move arm assembly (4) and the circle to the desired location.When the centershift lock pin is at the correct hole in arm assembly (4) , centershift lock switch (6) is moved to the ENGAGED position. When centershift lock switch (6) is moved to the ENGAGED position, solenoid valve (2) redirects the power train oil from the transmission filter in order to push the centershift lock pin into arm assembly
