G70B

With a wide range of performance to choose from, the B Series rotors are easy on the budget

Easy to adjust and maintain, Hunter's G70B golf and large turf rotor is also the ideal choice for the customer on a budget. The B Series rotors provide all the standard features you want for mid-distance coverage including a time-tested gear drive, convenient through-the-top servicing, and a sturdy, impact-resistant flanged body. Plus Hunter's precision-engineered PressurePort™ nozzling system reduces velocity and pressure to the secondary nozzles while increasing droplet size. The result is they deliver uniform distribution every time.
