A mobile center-pivot irrigation unit capable of irrigating small and irregularly-shaped fields is disclosed. The unit has two wheel-mounted irrigation carriages which support a single irrigation pipeline which is suspended between the two carriages. The first carriage is a light-weight steerable tractor with a pivot attachment mounted on its frame. The second carriage has two pivoting wheels which lock into position, thereby allowing the carriage to be either towed by the tractor, or to move in a circle about the tractor and pivot point. The unit is capable of being driven from field to field by a single operator and may be connected to a variety of irrigation water sources. Once connected to a water source, the second carriage wheels are repositioned and a water turbine powers the second carriage in a circular path about the first carriage as the unit sprays irrigation water onto the field.
