How do I fix or adjust the sprinkler heads?

My sprinkler head will no rotate to the right. I have tried everything. Is it possible the gears are shot? Please help.

it should say on the top of the head what kind it is usually rainbird, hunter or irritrol ... usually if there is a change in coverage it is diue to a pressure change in the water supply ie a leak in the line some sprinklers are installed with both mist heads and rotor heads on the same line . the mist heads of most brands you just grab it and twist it to turn the spray in a different directionand there is a set screw in the middle of the top of the nozzletightening it makes it shoot not as far ,,, loosening it (turning to the left ) makes it shoot further as for the rotors there should be a hole with arrows pointing to the left and right fror arc adjustment and a set screw that runs down thru the nozzle that adjusts the lengthhope this helps
