  • Patent number: 7270200
    Abstract: A working vehicle having a pair of left and right HSTs having hydraulic pumps, hydraulic motors and trunnion shafts for regulating the drive speed of the hydraulic motors by varying compressed oil from the hydraulic pumps into the hydraulic motors, in which one hydraulic pump is disposed parallel to the other hydraulic pump in the forward or rearward direction, including drive wheels driven by the HSTs, respectively, a pair of relay shafts between a pair of steering levers for independently operating the trunnion shafts and a pair of trunnion shafts, first connection members for connecting the steering lever and the relay shaft to each other, and second connection members for connecting the relay shaft and the trunnion shaft to each other, and first connection members for connecting the steering lever to the relay shaft to each other, and second connection members for connecting the relay shaft and the trunnion shaft.

  • Patent number: 7051499
    Abstract: As an embodiment of the present invention, a brake pedal 69 for braking right and left rear wheels 3 and a parking operation member 78 for maintaining a step-on condition of the brake pedal 69 are provided on a step 67. As a result, the step-on condition of the brake pedal 69 can be maintained by, for example, stepping on the parking operation member 78 with the left foot after applying the step-on brake of the brake pedal 69 with the right foot. Thus the body can be stopped without using hands and the stopped condition can be maintained over an extended period of time. Braking and parking operations of the body are simple, and moreover, an improved right-and-left weight balance of the body improves the traveling body in operation, and operations at the mower deck side. In particular, operation related to mowing height adjustment can be improved.
