Hunter Rotor Adjustment Tool
Rotor Adjustment Wrench
The Hunter adjustment wrench consists of a 3/32 allen key, two convenient finger loops for gripping and an opposite side arc adjustment key for all your Hunter rotor adjustments. You can also just use a 3/32 allen key for radius adjustment.
Adjusting your rotors yourself is easy. Most residential rotors are adjusted the same way. See the video linked to our item page for details. The Hunter Gear Drive Adjustment Tool suits all Hunter Geardrive sprinklers. Also used for changing nozzles and lifting the pop-up riser. Another helpful tool is Hunter's Nozzle Insertion Collar.
This Adjustment Wrench also fits some Toro & Rainbird Gear Drives.
