Roller harrow (optional)
The roller harrow consists of
•
harrow tines (Fig. 30/1)
•
press rollers (Fig. 30/2).
The harrow tines close the seed furrows.
The press rollers press the seed into the furrows.
The 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 arrangement angle of the harrow tines
•
the roller pressure

The roller harrow (Fig. 31/1) can be rapidly re-
placed with the exact harrow (Fig. 31/2).
The tramline marker (Fig. 31/3) can be used in
combination with the two devices.
