Abstract
This roller () comprises a tubular support structure () of horizontal axis (X-X) adapted to be rotatably mounted on a tractor-drawn support frame. A series of semi-hollow tyres with a dome-shaped profile are threaded onto this tubular support structure and enable a series of parallel furrows to be formed in the earth. The tubular support structure () comprises a framework formed by a plurality of bars () joined together by two circular end cheeks () between which these bars extend axially. The tyres () are mounted on the bars of the framework, forming with the latter an assembly that is connected for rotation and translation.
