Adjust angle of attack of wheels by means of shifting handle (A) to positions (B), (C) or (D), as required. Below follows a description of possible adjustments and the effect that each position has on the ground.

Position B. The wheels press down on and collapse the side walls of the furrow.

NOTE: Appropriate for graveled and clay soils with a high straw content.

Position C. The wheels press down on the side walls of the furrow and push the loose soil towards the centre of the furrow.

NOTE: Appropriate for (dry and medium humidity) graveled and clay soils with medium straw content.

Position D. The wheels press down on the side walls of the furrow and push the loose soil towards the centre of the furrow.

NOTE: Appropriate for (dry) graveled and clay soils with a low straw content.
