7. Filling the container
Using the tarpaulin covers
The drill is equipped with tarpaulin covers that can be rolled open with cranks located at its front and rear
edges, see Figs. 16–17. When filling the fertilizer container, you need only open the front part of the tarpaulin
cover, and similarly, when filling the seed container, only open its back part. This will prevent mixing up the
fertilizers and seeds when filling the containers. During transport and sowing, the tarpaulin cover should
preferably be kept closed and held in position with rubber mounts. This will avoid impurities penetrating the
containers and securing the cover in position.
Caution! On machines equipped with markers, the front edge crank must compulsorily
be mounted whenever working with rubber holders, see Fig. 16. Otherwise, the crank can
come into contact with a marker arm, leading to the risk of damage.

Use of sieves
Standard sieving equipment is normally fitted to the fertilizer and seed containers of JC seed and fertilizer drills
(this may vary by country and market). These sieves prevent foreign objects from causing feeding
disturbances, or fertilizer crumbs etc. developing in the feeding equipment. The fertilizer sieve must always be
kept in place during container filling and seeding. The seed sieve must also be in place except in the event of
certain exceptions.
Such exceptions include large or elongated seed shapes, which may be too large to fall through the sieve. For
example, many types of oat cause problems, as the grains are long and light.
If it is reasonable to suspect
that the seeds will not be able to pass through the sieve, the sieves must be temporarily dismantled
and removed from the container. When filling or seeding without sieves, special attention must be paid
to ensure that no foreign objects enter the feeding equipment, i.e. remnants of sack, tools etc.
Timing of the filling
When starting sowing, it is recommended that the machine be moved to the field in empty condition. Fertilizers
and seeds are delivered to the field, i.e. with a trailer, and seed drill filling is carried out at the side of the field
block. If the machine must be filled at a distance from the block to be sown, special caution must be exercised
during transport with full containers.
Caution! The maximum transport speed of 30 km/h may only be used on roads in good
condition, and containers must be empty! The maximum permissible driving speed with
full containers is 15 km/h! On potholed, rocky or extremely narrow roads, the transport
speed must be adjusted downward according to circumstances.
Monitoring of container levels is possible:
