<p>The removal implement has a chassis hauled over the soil and with two driven wheels bearing against each other so as to grip the haulm between them and pull it free. The two wheels (19), whose axes (14) extend in a plane at right angles to the travel direction and slope downwards towards the outside, and which are of resilient material at their peripheries at least (21). At the bottom and where they bear against each other they form vertical contact faces between which the stems are gripped, and are driven in order to exert the necessary tractive power.</p> |
