A wobbling irrigation sprinkler head is provided for use on a self-propelled mechanically moving irrigation system, such as a center pivot field irrigation system having the wobbling sprinkler head facing downward from the water supply conduit. The sprinkler head has a base for attaching to a pipe or to the central water supply conduit which base has nozzle mounted therein for directing water against a wobbling water deflecting head which is movably attached to the base and supports a deflector pad. The deflector pad has a deflection surface of predetermined shape with water deflecting grooves formed therein for rotating and wobbling the water deflecting head. The deflecting head has a loose fitting sleeve portion surrounding a support arm on the base and the base has a removable nozzle insert holder having a flange to loosely hold the deflecting head thereto. A magnet is mounted in the sprinkler head base to attract a ferric metal washer mounted the sprinkler head wobbling deflecting head to tilt the wobbling water deflector head relative to the base to cock the deflector head to initiate the wobbling in the deflector head.
