1.2. INTENDED USE
The cultivator is a universal tool for the cultivation of the top layer of
soil to the depth of 5 cm to 15 cm. It is designed for use after harvest and
before sowing following ploughing or in soil cultivation without ploughing,
when the vegetation remains are not covered but mixed with the top
soil layer (i.e. mulched). In combination with the integrated seeder, the
machine can be operated for soil cultivation and seeding. The cultivator
can be used on all types of soils including those with stones thanks to
the use of elastic suspension of the harrow discs. The harrow allows for
opening and mixing of the soil and in connection with the packer also for
packing and compressing of soil. Due to the resistance to clogging the
harrow is well suited for the cultivation of tall stubbles which remain after
the harvest of crops and corn and for cultivation of aftercrop intended to
be used as fertiliser.
1.3. CULTIVATOR DESIGN
The cultivator structure comprises the main frame built of sections,
the service assembly frame, the harrow discs with maintenance-free
hubs, the rear round packer, and the seeder hydraulic lift.
No person is allowed to remain on the machine or within
its operating area when the cultivator is working.
