Depending on the choice of machine, two different metering systems are available. The seed drills with a single hopper are equipped with injector metering: TERRASEM 3000 D to V 6000 D as well as V 8000 D / V 9000 D, including all CLASSIC models without the FERTILIZER system.
All TERRASEM FERTILIZER double seed hopper machines are equipped with a pressurised hopper system. The two-part hopper with a fixed 60:40 partition can also be filled with 100 % seed. Integrated pressure differential sensors ensure the reliability of the system.
On all machines with pressurised hoppers, it is possible to apply two different components such as seed/seed or seed/fertiliser. In addition, a third component can be sown by the TEGOSEM.
The TERRASEM metering systems are designed for the highest possible precision and ensure that exactly the right amount of any given seed type is used, even in the most difficult operating conditions.
The TERRASEM 3000 D to V 6000 D are fitted with one metering system and the V 8000 D and V 9000 D have two metering systems.
All TERRASEM models with double seed hoppers have two metering systems.
Metering wheels can be changed quickly and easily, dependent upon seed rate and type.
The metering unit is electrically driven, controlled via a radar sensor or ISOBUS signal from the tractor.
Seed rates between 1.5 kg and 420 kg at 12 km/h can be set conveniently directly from the cab.
Pre-metering is installed as standard for full field coverage.
A high volume of air and a low air velocity protect the seed and any dressing against damage. Together with the precision metering system and large distributor heads, this system delivers uniform seed grain placement.
Maximum effectiveness of seed and dressing is ensured
Special distributor inserts can be used to alter the row spacing.
On the 8 and 9 metre wide seed drills, both distributors are automatically lowered hydraulically during the folding process.
The seed is fed uniformly to the distributor in an air stream that passes up the riser tube. The large diameter of the distributor guarantees precise lateral distribution of the seed into each of the coulter pipes.
