    摘要: A four wheel drive vehicle with dirigible front wheels, comprising a main propelling drive transmission, and a front wheel drive transmission connected to the main transmission. The front wheel drive transmission is switchable between a first four wheel drive mode in which the front wheels and the rear wheels are driven at a substantially equal peripheral speed and a second four wheel drive mode in which the front wheels are driven at a higher peripheral speed than the rear wheels. The front wheel drive transmission includes a piston operable by a hydraulic control system including a control valve mechanically interlocked to a steering section of the vehicle for switching the front wheel drive transmission from the first drive mode to the second drive mode. The piston, which normally is biased toward a position for the first drive mode, is movable against the biasing force to a position for the second drive mode when the front wheels are steered to an angle exceeding a predetermined angle.

    摘要: A hood for enclosing a radiator and an engine has a hood grille formed in a front surface of the hood. The hood grille includes a front wall, and right and left side walls extending from opposite sides of the front wall. The front wall defines intake openings for drawing in air for the radiator. The right and left side walls include bent portions bent substantially at right angles to the front wall. Opposite end regions thereof are secured to the right and left side walls by fixing devices. Hood grille netting extends over an entire area of the intake openings and covers at least parts of the right and left side walls. The opposite end regions of the hood grille netting are bent to correspond to the bent portions. The hood grille netting is secured to the hood grille by bolts and spacers to define spaces between the hood grille netting and the right and left side walls. These spaces communicate with the intake openings.

    摘要: A speed control system for a working vehicle having a stepless transmission with a speed control shaft disposed on one side thereof and shiftable between a driving region and a neutral position. This speed control system includes a shift lever disposed on one side of a driver's section for setting a traveling speed of the tractor, while the speed control shaft of the stepless transmission is disposed on the other side of the driver's section. The shift lever is operatively connected to the speed control shaft through a link mechanism. The link mechanism includes a neutralizing mechanism in an intermediate position thereof adjacent the shift lever for returning the speed control shaft to the neutral position.

    摘要: A running apparatus for an agricultural vehicle comprising an oil stepless change speed device, an oil circuit for an oil pump and an oil motor to actuate the oil stepless change speed device and an accumulator. The accumulator accumulates a surplus of an output pressure of the oil pump when the pressure is higher than a predetermined value and discharges the accumulated pressure when the output pressure of the oil pump is lower than the predetermined value.
