Disclosed herein is an hydraulic motor powered planetary drive self-propelled irrigating apparatus comprising a distributing pipe supported by a plurality of towers, each tower frame carrying hydraulic fluid feed and return lines for two motors which are part of each power unit. Each of the two motors is mounted in a bracket rigidly connected to one end of the tower frame, and has an output shaft coupled to the rotatable input shaft of a planetary gear reducer assembly housed in a rotatable hub casing driven by said gearing. The wheels of each tower are mounted on the rotatable hub casings of the two power units.
