Variocast seeders are typically used to sow small seeds e.g. OSR, stubble turnips, cover crops as well as to apply slug pellets.
The Variocast range includes the Variocast 8, a pneumatic mechanical seeder where the seed roller metering is driven by a land wheel. The Variocast is also offered as an electronic seeder, where the metering roller is driven electronically utilising a GPS receiver for accurate forward speed metering - the 8E, the 8E Pro and the 16E Pro.

It cuts seed rates and establishment costs whilst improving yields - utilise a Variocast to take advantage of till-seeding techniques and improve gross margins.
With the subsoiler working at a medium depth and the Variocast Seeder set to seed in bands behind the legs you make serious in-roads into output and cost. Furthermore the loosened sub soil promotes long, strong taproot growth.
Sowing in bands gives each plant the room to develop through better light interception, branching out and encouraging flower heads on the lateral branches as well as the main stem and overall requires less seed whilst still attaining good yields.
FEATURES & BENEFITS
Precise seed metering
Unlike most other types of seed applicators the Variocast Seeder uses individual metering wheels for each seed outlet enabling extremely accurate metering and guaranteeing the same amount of seed is fed to each outlet. This is crucially important when using low application rates.
Four types of metering rollers are available for the Variocast.
The Variocast 8 seeder comes with coarse (green) and fine (blue) seed rollers as standard -the third or fourth seed rollers can be supplied as optional extras.
There are eight 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 applying seed in a band behind a five leg subsoiler with one outlet per leg, running directly in-line with each leg.
Even seed distribution
The Variocast Seeder can be used for either band application (recommended for OSR) or to spread seed evenly across the whole width (recommended for cover crops and environmental establishment scheme mixes).
The standard broadcasting outlets spread the seed in a overlapping pattern for an even full width coverage. Alternatively modified outlets are used for band application of seed into rows. The seed placement is adjusted by changing the height of the distribution outlet, this will give you wider or narrower bands.
Variocast seeder's are supplied with a strong mounting plate which assist fitting to whatever cultivation machine is chosen. The hopper and chassis are built to withstand the rigors of high speed seeding in hard ground.
The amount of seed applied is controlled by the speed of the metering roller, which is adjusted until the desired application rate is achieved.
The in-cab control box facilitates a simple calibration and rate on the move adjustment on the electronically controlled version.
Calibration is performed by removing the metering roller cover and using a calibration tray.
Forward speed related metering
Mechanical Variocast Seeders come with spoked land wheel drive to give constant forward speed related metering. The electronic, 8E, 8E Pro and 16E Pro Variocast seeders use a GPS receiver for accurate forward speed metering.
On some tractors it is possible to connect to the tractors own GPS system. Forward speed related metering means accurately maintained application rates on high draft machines and in awkward shaped fields where ground speed may vary.
