The invention relates to an agricultural machine in the form of a seed drill (35), comprising a frame (4) having coupling points for coupling to a tractor (2). The coupling points (8, 9) are located at the rear of the frame (4), the arrangement being such that the seed drill (35) can be pushed by the tractor (2). Means are provided with the aid of which the seed drill (35) is adjustable from the tractor (2) to an operative position in the front of the tractor (2) as well as to an operative position aside the tractor (2). The seed drill (35) has a roller (32) positioned in front of the seed drill (35). Instead of the seed drill (35) at the front of the tractor (2) there may be provided a crumbler roller (66) that can be positioned in front of as well as aside the tractor (2).; Hereby the rotary axis of the crumbler roller (66) is adjustable relative to the direction of operative travel of the machine.
