Abstract
A working vehicle includes a PTO shaft to transmit power of a propulsion shaft, a PTO clutch including a first rotor to be rotated by the power of the propulsion shaft, a second rotor to transmit the power to the PTO shaft, a press to be moved by a pressure of operation fluid between an engaging side on which the first rotor is engaged with the second rotor and a disengaging side, and a PTO brake to brake the PTO shaft when the press is positioned on the disengaging side, a control valve to control the pressure of the operation fluid to be applied to the PTO clutch, a rate setter to set a reducing rate at which the pressure of the operation fluid is reduced, and a controller to control the control valve based on the reducing rate.
