5.14 Roller harrow with contour guidance
The roller harrow consists of

harrow tines (Fig. 68/1),

press rollers (Fig. 68/2).
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.

If the roller harrow is not being used, it can be raised from the ground.
