  • Patent number: 8666621
    Abstract: A PTO control system for allowing selection between an independent PTO mode and an interlock PTO mode, comprising a mode-switch command input device 11 for giving an instruction on selection between the independent PTO mode and the interlock PTO mode, a PTO setting device 12 having an engaging position for producing an engaging command and a disengaging position for producing a disengaging command of the PTO clutch, and a PTO control unit for controlling a PTO clutch in response to a pedal operational position of a brake pedal, a mode selected by the mode-switch command input device, and a position selected by the PTO setting device. PTO mode switch implementation processing is suspended when the PTO transmission system is in a power transmittable state, while the PTO mode switch implementation processing is permitted when the PTO transmission system is in the power non-transmittable state.

  • Patent number: 8251868
    Abstract: A travel operation structure of a work vehicle, comprising a pair of left and right side brake pedals disposed on either the left or right of a steering wheel; a hydro static transmission for changing the speed of travel; and a stop operation pedal disposed on the other of the left and right of the steering wheel; wherein the corresponding left or right side brake is applied when one of the pair of left and right side brake pedals is depressed, and when both the left and right side brake pedals are depressed, both the left and right side brakes operate, and travel is stopped; and when the stop operation pedal is depressed, operating oil of the continuously variable speed change device is directed into an oil tank, and the continuously variable speed change device is switched to a neutral stop position for blocking transmission of power to the travel device.

  • Patent number: 6250414
    Abstract: To provide a working vehicle with a simple body structure, an HST case containing a hydraulic stepless transmission is disposed between an engine adjacent one end in a fore and aft direction of a vehicle body, and a propelling transmission case disposed adjacent the other end in the fore and aft direction. The HST case, with the engine and propelling transmission case, forms the vehicle body. With this construction, a driving deck is located at a relatively low level so that the driver may board and alight from the deck with ease. Despite the low level of the deck, the bottom of the vehicle body is at a relatively high level to be free from contact with projections on unleveled terrain. Frame strength may be increased where the HST case is connected between a main clutch housing connected to the rear of the engine and the propelling transmission case.
