摘要

The scraper (26) has a support (38) connected to a sowing machine, and clearing wheels (36) supported at the support in a rotatable manner such that the wheels roll on a ground and aligned opposite to each other in V-shape along driving direction of the sowing machine. The wheels have outer diameter of 450 mm, where an angle of incidence of the wheels is less than 12 degree relative to the driving direction. The wheels carry a toothed ring on outer side, where outside diameter of the toothed ring forms the outer diameter of the wheels. An independent claim is also included for a sowing machine.
