ABSTRACT:
A hose-drum irrigation machine including a hose-laying device by which a hose-guide through which the hose passes is reciprocated parallel to the axis of rotation of the hose-drum as the drum is rotated. The hose-laying device includes a carriage to which the reciprocation is applied and the hose-guide is mounted for movement relative to the carriage parallel to the axis of rotation of the drum between two extreme positions adjacent the ends of the carriage. The hose-laying device includes control means responsive to the position of the hose-guide in the length of the carriage to control a motor driving the drum. One of the extreme positions of the hose-guide on the carriage corresponds to maximum permitted drum speed and the other of the extreme positions corresponds to zero or minimum drum speed.
