Structure and function
5.15 Roller harrow (optional)
The roller harrow consists of
• Harrow tines (Fig. 84/1)
• Press rollers (Fig. 84/2).
The harrow tines close the seed furrows.
The press rollers press the seeds into the fur-
rows. Better soil contact means more humidity is
available for germination. Voids are closed and
obstruct snails' access to the seed.
The following are adjustable
• the working depth of the harrow tines
• the angle of the harrow tines
• the roller pressure

5.16 Two-row disc array
The discs, which are set obliquely to the direction
of travel (Fig. 85/1), prepare the seedbed.
The following are adjustable
• the working intensity of the discs over the
working depth of the disc array
• the length of the outer discs for adaptation
to varying soil conditions
• the two outside hollow discs (Fig. 85/2) in
vertical direction.
Fig. 85
Correctly set outer discs and outside hollow discs prevent the culti-
vated soil from egressing laterally from the working area of the ma-
chine.
The elastic rubber sprung suspension of the
individual discs enables
• adaptation to soil unevenness
• evasion by the discs when hard obstacles
are encountered, e.g. stones. This protects
the individual discs against damage.
