Unlike most other types of seeders the Variocast uses individual metering wheels for each seed outlet enabling extremely accurate seed metering and guaranteeing the same amount of seed is fed to each outlet.
This is crucially important when using low seed rates and small seeds for example with hybrid Oilseed Rape down to under 2kg/ha
Three types of metering rollers are available for the variocast.
The standard roller
The small roller
The micro roller

Any two of these rollers are supplied as standard with the Variocast, the third can be purchased as an extra.
There are 8 seed outlets as standard but it is possible to blank off a number of them using the Blanking Roller and Stop Kit, for example for band sowing behind a 5 leg subsoiler with one outlet behind each leg.
