Abstract: A disc device for an agricultural machine includes at least one disc implement, an arm, at one end of which the implement is journalled in bearings at an axle, and a bearing, which is arranged at the opposite end of the arm and is adapted to be fastened at a transverse beam on the frame of the agricultural machine. The disc device includes in the circumference direction of the disc implement mainly equally distributed, freestanding, out towards the periphery radially extending, protruding parts, wherein each protruding part has an outer edge, which extends in the range 15-75 degrees in relation to the plane of the disc implement.

Abstract: The invention refers to a Holder having grip means for a detachable tablet computer or the like with a screen, said holder having a frame, which comprise holder means for reception of said tablet computer. The holder is provided for controlling a machine and comprises a hand grip side or hand grip side portion with buttons or sensors, which are provided for operating a machine by means of said tablet computer mounted thereon and which are able to be activated through finger touch/contact of said holder in order to communicate with certain functions of said tablet computer and/or of the machine which it is arranged to control. Said machine could be an agricultural implement, like a seed drill or the like.

Abstract: Agricultural machinery and procedure for an agricultural machinery (11) that comprises metering devices (B1, B2, Bn) placed laterally in the agricultural machinery so as to provide a number of parallel metering rows (n), each one of the metering devices (Bn) being connected to at least one control unit (22) for the individual control of each metering device, the control unit (22) receiving a first signal, which acts on the control unit (22) to either start or stop the metering from the laterally outermost positioned and activated metering devices (B1), the control unit (22) receiving a second signal, which acts on the control unit (22) to either start or stop the metering from at least one of the laterally activated second outermost positioned metering devices or groups, the calculation unit, with the aid of the instant of time of the first signal and the instant of time of the second signal as well as the speed of the agricultural machinery, calculating the individual instants of time of start or stop of the

Abstract: A sow housing for piecemeal sowing of seeds. The sow housing includes a seed bin and a rotating seed element having a wall that has a plurality of through holes. Each hole is arranged to, during a first part of the revolution of the hole, retain a seed as a consequence of pressure difference between the two sides of the wall. A cover is arranged to cover each hole during a second part of the revolution of the hole.

Abstract: The invention relates to a roller cylinder (1) comprising band rings (6) which are attached to a centre axis (17, 17a, 17b). The roller cylinder comprises at least two band ring segments (14, 14a, 14b) consisting of an outer, substantially circular portion (15), an inner portion (16) and a radial portion (18) extending substantially radially between the inner and outer portions, said inner portions of the band ring segments being fixed by means of fastening means, such as screws (19, 20, 19a, 20a, 21a, 19b, 20b, 21b), to the centre axis and abut the centre axis at least at the attachment points of the fastening means between the inner portion of the band ring segments and the centre axis. The invention also relates to a band ring segment included in a roller cylinder provided with band rings.

Abstract: An agricultural machine including a seed metering device to meter seeds for the distribution to the ground across which the agricultural machine moves. The seed metering device embraces a wall that is arranged to rotate. The seed metering device is furthermore arranged to communicate with a pressure actuating appliance for providing a wall pressure difference between a seed reception side, high-pressure side, of the wall and a side, low pressure side, of the wall that is opposite the seed reception side. The wall is provided with a plurality of through retention openings for the reception on the seed reception side of the wall, by the wall pressure difference, of seeds at the retention openings. Then, the seeds are transported, by the rotation of the wall, through a wall transportation distance whereupon they are released from the wall.

Abstract: Agricultural machine embracing at least one drilling unit including a support device as well as a seed metering device. The drilling unit is movably connected with a structural member embraced by the agricultural machine. The seed metering device is fixedly connected with the support device of the drilling unit and the seed metering device includes a chamber for seeds arranged to be supplied with a positive pressure where the seed metering element constitutes a wall limiting the chamber and in which holes or recesses are arranged. The holes/recesses connect the chamber with the surroundings, with the purpose of, by the pressure difference developed hereby, attaching and transporting seeds at the holes/recesses of the seed metering element. A seed metering line has an inlet in the chamber, with the purpose of, by the positive pressure in the chamber, creating an air flow for the transportation of the seeds from the chamber through the seed metering line to a drill furrow.
