Abstract
An agricultural machine has a longitudinal variable drive shaft enclosed by a tubular casing for coupling to a power take-off shaft of a tractor. The drive shaft and power take-off shaft can be aligned and coupled to each other. The agricultural machine is further provided with a hitch bar and a support device is mounted on the hitch bar comprising a strut pivoted on the hitch bar so as to fold upon the bar in its axial direction. The other end of the strut engages and supports the drive shaft and a guide member has one end pivotally connected to the tubular casing and the other end pivotally connected to the strut so as to be slidable therealong.
