Agricultural machine with associated wheel and roller enabling furrow creation |
摘要 |
An agricultural machine having a first frame and a roller with a tube mounted about a first axis. A second frame is connected to the first frame and a wheel, which includes a rim mounted about a second axis. The wheel has a tire and the roller has a covering around the tube. The covering and the tire tread have moldings defining a pattern element repeated in a transverse direction parallel to the first axis and to the second axis, respectively. The pitch of transverse repeat of the pattern element of the roller and the pitch of transverse repeat of the pattern element of the wheel are equal to the nearest 10%. The pattern elements define ribs the height of which on the roller and the height of which on the wheel are equal to the nearest 90%. |
