The adjustable stator is preset at the factory to match the nozzle installed in the rotor. The purpose of the stator is to maintain a consistent and desirable speed of rotation. Rotors that turn too fast cannot reach their published radius distance. Rotors that turn too slow will irrigate with a higher precipitation rate per revolution causing wet spots and run-off.

Prior to removal of the upper snap-ring assembly, the rubberized logo cap must be removed and the riser assembly must be pressed below the snap-ring’s rubberized seal. If the procedure below is not followed, the upper snap-ring assembly cannot be removed from the G900 Series rotors:


Caution! The riser assembly is under spring tension. Eye protection should be worn and safe-handling procedures followed when servicing this product.

Tools Needed (varies with riser model)

• T-Handle Tool – PN 053191

• Hunter Wrench – PN 461720

• Snap-ring Tool – PN 052510

• Needle-Nose Pliers

• Flat Blade Screwdriver

• Phillips Screwdriver

In hydraulic installations, the flange compartment should be used to make the Control Tubing connections to the rotor. This allows for tubing connections, pressure tests and flushing of the control lines - all without digging.

Electric Valve-In-Head TTS rotors are equipped with a selector to control operation of the rotor. The selector is located on the flange compartment’s lid. From the factory, the selector is set to the AUTO position which is located midway between the ON and OFF positions (fig 1).

Several tools are available to make ON-AUTO-OFF selections:


• T-Handle Tool – PN 053191

• Hunter Wrench – PN 461720

• Snap-ring Tool – PN 052510

The MP Rotator has a lower precipitation rate than typical spray heads, so your run times need to be lengthened. Your run times with the MP Rotator may be two to three times longer than a standard spray zone.

Below is a chart indicating the maximum wire runs that can be used
when installing Hunter AC solenoids and valves.
