Abstract: A fixing device is for a bucket front, wherein the bucket front forms a wear part in an excavating bucket comprising at least one side portion. The side portion is formed with a coupling piece comprising at least two projections with recesses, wherein the projections fit in a complementary manner into recesses in the bucket front or in a coupling part fixed to the bucket front, and wherein the bucket front is connected to the coupling piece by a locking bolt extending, in the direction of the side portion, through openings associated with the side portion and the bucket front.

Abstract: There is disclosed a semi-mountable plough comprising an elongate plough frame having a long forward frame section (1) carrying a plurality of plough bodies (2), a short intermediate section (3) pivotally connected to the rear end of the forward section (1), and a rear frame section (5) pivotally connected at its forward end to the rear of the intermediate section (3), with the plough being of a reversible type and the sections (1, 3, and 5) being pivotable relative to each other in a generally horizontal plane to take up new positions suitable for movement of the plough in a reverse direction.

Abstract: A combination of a semi-mounted reversible plough (10) and a seed preparation device (11) are towed behind a tractor in order to carry out a ploughing action and a seed preparation action during a single pass over the ground.

Abstract: A hole opener used in conjunction with drilling in at least one of boulder and rubble stone formations includes first and second sets of cutters. Each of the cutters of the first and second sets of cutters has cutter teeth thereon and further include a shaft. The hole opener also includes a tubular carrier body, a first device for fixing the first set of cutters to the tubular carrier body so that the first set of cutters is positioned in a common first lateral plane with respect to a longitudinal axis of the tubular carrier body, and second device for fixing the second set of cutters to the tubular carrier body so that the second set of cutters is located in a second lateral plane with respect to the longitudinal axis of the tubular carrier body and at an axial distance from the first set of cutters along the longitudinal axis.
