  • Patent number: 8127872
    Abstract: A transmission device for a work vehicle, comprising a travel drive system for transmitting engine power to a travel device; an implement drive system for transmitting engine power to an external power take-off shaft; braking operation tools for a braking operation; a stop operation mechanism provided to the travel drive system and capable of interrupting the transmission of power to the travel device; and a hydraulically operated PTO clutch for interrupting the transmission of power to the external power take-off shaft, the PTO shaft being provided to the implement drive system; wherein the stop operation mechanism and the PTO clutch are linked with the braking operation tools so that the stop operation mechanism is operated to a power transmission stopping position and the PTO clutch is disengaged along with a pressing operation of the braking operation tools, and the PTO clutch is engaged along with a press-releasing operation of the braking operation tools; and an operation timing is set so that the PT

  • Publication number: 20090213422
    Abstract: An apparatus, method, and system for processing character data is provided, which selects a format of the character data to be used for generating print data. When a user instruction for printing character data according to character command data specifying the output of the character data is received, the format of the character data is selected based on the character command data.

  • Patent number: 7337870
    Abstract: A working vehicle provided with a hydraulic continuously variable transmission, has a plurality of wheels; a vehicle body supported by the plurality of wheels; a hydraulic continuously variable transmission that is supported by the vehicle body, and that has a speed change actuation shaft; a speed change pedal operatively linked to the speed change actuation shaft for controlling the speed change actuation shaft; and a neutral bias mechanism for biasing the speed change actuation shaft toward a neutral position. The bias mechanism includes a cam portion that pivots together with the speed change actuation shaft; an operation member that abuts against the cam portion; and a biasing means for biasing the operation member toward the cam portion. The biasing means is disposed above a step surface of a riding step.

  • 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.
