The Rotor Meter (gravity) and Rotor Meter Air Force (fan assisted) applicators are designed to accurately meter and apply seed or granules, ensuring a uniform application rate across the desired working width.

Typically integrated as additional applicators on drills and other planting machines, they can be specified with either single, double or triple outlets.  The Rotor Meter is commonly mounted to potato planters to deliver sulphur granules and slug pellets. Alternatively, on salad or vegetable crops micro-granular fertiliser is often applied after establishment.
