摘要： A four wheel drive working vehicle having a hydraulic block for covering one side of a propelling transmission case, an engine, and an HST attached to a side of the hydraulic block remote from the transmission case. The HST includes an input shaft for transmitting drive from the engine, and an output shaft extending through the hydraulic block for transmitting the drive to a transmission line in the transmission case. The vehicle further includes a drive transmission mechanism for selectively transmitting the drive from the transmission line to rear wheels, and a transmission shaft for transmitting the drive between the drive transmission mechanism and the transmission line in the transmission case. The drive transmission mechanism is attached to the side of the hydraulic block where the HST is attached. The transmission shaft extends through the hydraulic block.

摘要： A four wheel steering tractor comprising a grass cutting system vertically movably mounted in a lower space of the tractor between front and rear wheels. The grass cutting system carries gauge wheels disposed at opposite lateral sides in rear regions thereof. An interlocking structure between a steering wheel and the front and rear wheels includes a front drag link extending from a pitman arm toward the left (or right) front wheel, and a rear drag link extending from the pitman arm toward the right (or left) rear wheel. This interlocking structure places the center of tractor turning approximately on a straight line extending through the gauge wheels and adjacent one of the gauge wheels.

摘要： A transmission for an agricultural working vehicle is provided which includes a gear type forward speed changing mechanism and a wrapping connector backward driving mechanism selectively operable to connect an input shaft and an output shaft. The input shaft carries a plurality of change speed gears and a driving sprocket fixed thereto. The output shaft carries a driven sprocket relatively rotatably mounted thereon and operatively connected to the driving sprocket by a wrapping connector, and a shift gear slidably splined thereto and including gear portions selectively engageable with the change speed gears. The shift gear is linked to the driven sprocket by an engagement mechanism to provide a backward drive state when shift gear assumes a position other than change speed positions.
