Arrangement for converting a tractor-drawn roller for compacting ground in agriculture from its working position to a position more suitable for transportation and for reconverting said roller to the working position. The invention enables an, in its entirety, exceedingly simple and easy-to-manufacture design of the implement. Drawbar (10) consists of a round tube about which turn the two frame parts (9) securing the roller sections (2), when the hydraulic cylinder (12) presses the outer end of the roller sections down towards the ground and pivots their inner ends upward. Whereby the wheels (11) are secured at such points of the roller as to be pressed down towards the ground and as to raise the roller. |
