The mid mower 13 is lifted down by driving the cylinder device 24 in a reverse direction. A link 35 is fixed by means of a pins 21 at the hanging link 6 so that the link 35 extends downward in excess of the pin 21, and a upper end of the aforesaid rod 31 is fixed at a bottom end of the link 35 by means of a pin.
