Hunter builds a rotor for every yard size, from a compact 1/2-inch body to a long-throw 3/4-inch gear drive. Match the line to your zone radius and inlet, then standardize nozzles across the zone.

| SRM | 15 to 30 ft | 1/2 in | 6 | 30 to 50 PSI | 1 year | Small lawns on a budget |
| PGJ | 15 to 34 ft | 1/2 in | 8 | 30 to 50 PSI | 2 years | Small and mid-size lawns |
| PGP-ADJ | 22 to 52 ft | 3/4 in | 27 | 25 to 70 PSI | 2 years | Large lawns, standard PGP |
| PGP Ultra | 17 to 46 ft | 3/4 in | 34 | 25 to 70 PSI | 5 years | Upgraded PGP with Automatic Arc Return |
| I-20 | 17 to 46 ft | 3/4 in | 34 | 25 to 70 PSI | 5 years | Commercial-grade, stainless riser option |
The PGP Ultra and the I-20 share the same 34-nozzle rack, so one set of nozzles covers both. For 1/2-inch zones on smaller lawns, step down to the PGJ.
