Yes, drivers must have a CDL with endorsements to haul double trailers or triple trailers in North Dakota.
Federal regulations allow a farmer to operate within 150 miles of their farm without having a CDL and do not restrict the pulling of doubles/triple trailers; however, the regulations do require that the farmer operates with their state unless their state has a reciprocity agreement.
North Dakota and South Dakota have a reciprocity agreement in which North Dakota will recognize a South Dakota's farm vehicle operator; however, the SD operator has to abide by the same laws as North Dakota farmers. Therefore, a SD farm vehicle operator can haul doubles/triple trailers in SD; but they can’t haul in North Dakota without the properly license.
