Precision Seed Drills
Vicon Rau Unicorn
Precision in all Soil Conditions
UNICORN, the mechanical single seed drill for sowing pelleted beet seed. Renowned for its quality and reliability and proven adaptability to the different operating and adjustments, which arise in the field.
UNICORN, with its 6 to 24 row units configuration, easily copes with varying operating conditions. Of special note is the parallelogram design and the frame construction, which is as robust as it is variable.
With mechanically driven seed units folding/unfolding the frame and track indicator is accomplished from the tractor cab with a minimum of effort and executed by powerful electrically controlled hydraulics.

Unicorn - Frame
The rigid end-tow toolbars are available in working widths of 3m, 6m, 9m and 12m. The convenient and time saving parallel hydraulic folding is available in 6 m and 9 m toolbar versions. The transport width of all Unicorn models is a maximum of 3 metres.
The hydraulic, parallel folding mechanism allows UNICORN to be easily folded for transport on public roads. Alternatively, there is a lengthways towing facility available for the rigid 12, 18 and 24 row frames. Support or drive wheels on the mid and outer sections provide optimum ground contour following characteristics.
Unicorn - Sowing Elements
The sowing units – like the whole machine – are modular in design.
The basic element always remains the same and the equipment can be varied according to individual requirements. For mulch seeding, the front Farmflex wheel is simply replaced with a double cutting disc equipped with side zero pressure tyres. The trailing coulter draws a clean seed furrow for precise seed placement.
The Unicorn sowing elements are equipped with the V-press wheel as standard. The zero pressure rubber tyres do not allow soil to stick and provide excellent operation. The seed is covered with loose soil by adjustable coverer. The amount of covering soil is similar to that of the sowing depth ideal for wet and loamy soils.
Optional finger press wheels are recommended for heavy dry soil and soils susceptible to late frost. The seed is covered with loose soil by the adjustable coverer. The covering soil is lower than the sowing depth. A "micro climate" protects the germinated plant.
Unicorn - Seeding Heart
UNICORN operates as an internally filled drill, with chamber wheel speeds, which correspond to the normal sowing speed in practice. The adjusted chamber speed of the bearing borne chamber wheel minimises bounce and roll impulses, thus increasing the precision of seed placement. Guaranteed filling of each individual cell: The cell wheel internal filling principle for precise seed placement
Unicorn - Synchro-drive II
Electronic drive for highest precision. Complete control and monitoring of the machine from the tractor cab in accordance with ISO bus standard.
The latest Terminal universal ISOBUS terminal – IsoMatch Tellus offering two ISOBUS interfaces in one terminal, the ISOBUS shortcut button and a touch screen display. The IsoMatch Tellus is the first ISOBUS terminal in the world with the capability to operate 2 different (machine) screens through 1 terminal, without the need to constantly toggle between screens.
- Two ISOBUS screens at a glance
- Integrated tractor ECU programme
- RS-232 connection for a GPS receiver or other external sources
- Option to connect up to 4 cameras
- Multifunctional, ergonomic, user-friendly design
The in-cab mounted Visus (Opto Electronic Control) constantly monitors the operation of the machine alerting the operator of any malfunction within the sowing heart. The Visus counts seeds as they are sown. If there is an interruption in seed delivery, an audible and visual alarm is immediately triggered. The Visus indicates the area worked, working time and forward speed. Suitable for all seed types (except rape). High degree of operational reliability for contractors and farmers alike.
The Focus 2 terminal with b/w monitor is a cost efficient alternative for ISOBUS compatible machines of the Kverneland Group.
ISOBUS Intelligence - GEOcontrol
IsoMatch GEOcontrol - Cost saving with immediate payback
Seeding with GPS and GEOcontrol in combination with an electric driven precision drill is a major step towards precision and cost saving. These machines are all equipped with ISOBUS technology which with the help of the IsoMatch Tellus terminal, can be easily controlled.
Each electric driven seeding element, in combination with GPS and GEOcontrol, is automatically switched on or off in exactly the right place, ensuring there is no overlap with any row that has already been seeded. This is especially handy in triangular fields, on curved or irregular shaped headlands.
ISOBUS Intelligence - GEOseed®
GEOseed® - Precision at high end
GEOseed® is offered in two different levels:
GEOseed® Level 1 is the synchronization in the machines working width. This improves the distribution of seeds up to perfection in parallel or diamond pattern: Positive effects are the best use of nutrients, water and sun. Also the wind and water erosion is decreased.
GEOseed® Level 2 is the synchronization in the whole field. This is the necessary requirement for interrow cultivation, also across the seeding direction. GEOseed® is the only system in the world, that makes this mechanic weeds control possible!
The hoppers, made of special grade plastics, have a capacity of 35 litres.
They are mounted according to the working width with 2 or 3 outlets per unit.
Metering wheels of different sizes and materials are available to suit the application requirements of most types of micro-granule.
