The Mr.Mister can be retrofitted to most drive motors but it is a direct bolt on for the Mr. Manhole drive motors. The main components are the spray head which bolts directly to the Premier Model 40 - 2 1/2" or 2" hex drive motor & the Digga 2 1/2" 5DDS-11-MM via a special hardware kit that is shipped with the Mr. Mister along with detailed mounting instructions.
