PCT No. PCT/SE82/00179 Sec. 371 Date Jan. 17, 1983 Sec. 102(e) Date Jan. 17, 1983 PCT Filed May 18, 1982 PCT Pub. No. WO82/04085 PCT Pub. Date Nov. 25, 1982.A device at a combined bucket and frozen soil scarifier (/cable plough), where the bucket (13) and scarifier (10) are intended to be attached to a digger arm of an excavator or corresponding machine, and the width of the scarifier (10) is substantially smaller than the width of the bucket (10), and the bucket in digging position is intended to rest at its rear edge (14) against the scarifier (10), and the bucket at its upper portion is hingedly suspended by means of an axle (19) or corresponding member, and preferably by hydraulic means, for example at least one hydraulic cylinder (21), can be folded in the direction from the scarifier, whereby the scarifier can be utilized without the bucket being engaged. The device according to the invention is especially characterized in that a separate attachment (1-6,43,44) is provided, which preferably by means of a quick-coupling arrangement (3-6) is attached to a corresponding controllable attachment on the digger arm, and that the bucket (13) and scarifier (10) are located at and project downward from said separate attachment, so that the bucket and scarifier, in relation to the longitudinal direction of the digger arm, can assume either of two positions offset through 180 DEG in relation to each other.
