seeds, as well as form tracks in the field.
The use of Nova Combi to other purposes than the sated is prohibited. The machine is not meant
for example to transport materials with great speed or storing material in the containers of the
machine. The filling station of the machine should be located close to the field which will be sown
and the transport speed, when machine has a load should be in a reasonable relationship to the
container contents and road unevenness. Passenger transport with the machine is completely
prohibited!
Using the machine exceptionally for sowing only
If fertilizers are not being used, it is reasonable to move the partitioning in machine container to
its forward position and maximize the space for seed container.
If desired, for example due to the risk of soil drying out, to ensure that the seed is placed on the
bottom of the deepest opened groove, the seeds can be sown through the fertilizer container.
Calibration must also be done in this case by using the fertilizer side feeding device and
calibration trough. It must also be taken into account that the fertilizer side filters may not pass
through the seeds which will be sown. In this case, the screens must be removed.
In order to achieve the maximum drilling capacity, seeds may also be sown through both
containers simultaneously (
note : when sown through separate containers there is a 2 cm
difference in resulting depth). Please note that the calibrations must be then carried out for both
feeders and the sum of results forms a result describing the sowing rate. In the above special
cases, it is worth remembering that the sowing tables shipped with the machine apply.
Using the machine only for fertilizing
Tume Nova Combi can also be used for fertilizer placement only. Fertilizer in this case will be
filled into the fertilizer or seed container or to both. Special instructions related to the mere
fertilizer placement are quite consistent with the instructions of the previous section.
On filling the entire machine with fertilizer, it should be noted that the fertilizer is usually heavier
material than the seeds. Thus, the machine will not be filled completely and must comply with the
maximum total weight stated in technical specifications.
4. GENERAL GUIDANCE FOR SOWING
Sowing depth selection
Nova Combi is equipped with 2-disc coulters, where the right and left discs have different
diameters. The first disc essentially determines the seed sowing depth and the larger disc creates
a somewhat deeper groove for the fertilizers.
When selecting the sowing depth, consideration must be given the requirements of seeds and
ground moisture conditions. Find out in good time the suitable depth for sowing the seed and try
to match the sowing date so that in the suitable sowing depth sufficient moisture exists. A suitable
working depth for small seeds, normally alternates between 1-3 cm range and ordinary grains
have a suitable sowing depth of 4-5 cm. Always be cautious not to sow too deeply. On the other
hand, sowing low may end up with problems as seeds do not necessarily become covered.
It is important, that the smaller disc of Nova Combi 2-disc coulter reaches a moist part of the soil.
