摘要：
A selector valve operating mechanism is provided with operating pistons which are hydraulic pistons connected through an operation link to a spool of a PTO selector valve, an solenoid valve for hydraulically controlling reciprocation of the operating pistons, and a controller which is a control device for transmitting an operation signal to the solenoid valve. Control of operation of the solenoid valve moves the spool through the operating pistons and the operation link to switch the PTO selector valve.
