A wheeled irrigator carriage has a fulcrum around which a piping frame can rock at the ends of crop rows to lift one traction wheel of the irrigator and lower a second traction wheel at the other end of the irrigator into driving engagement with the ground. The second traction wheel has a power drive reversing member associated therewith. An independent higher speed power drive for the first-named traction wheel is provided. The piping frame also serves to deliver irrigating water from a remote source to a pair of spaced irrigation booms on the piping frame which may span several rows of crops. A massive hose reel is supported symmetrically above the fulcrum.
