Abstract: To increase the capacity of an extension attachment for a bulk material container comprising a frame (32) and a plurality of flaps (33, 34) linked to the frame (32), which are capable of swivelling and, in a swivelled-out position, surround an internal space (31) of the extension attachment, the internal surface (28) facing the internal space (31) of at least of one of the flaps (33) has a concave shape in the swivelled-out position.

Abstract: A baler for agricultural products has a chassis, a pickup, a transporting passage, a pressing chamber, a binding device, a discharging device, a working element performing working operations in the baler, a main drive shaft connected with the working element for driving the working means, at least one planetary summing transmission connected with an operative for driving the main drive shaft, a first drive unit including a cardan shaft and transmitting rotation with a first rotary speed to the planetary summing transmission, and a second drive unit transmitting a rotation to the planetary summing transmission with a second regulatable rotary speed, so that the planetary summing transmission summarizes the rotary speeds of the first and second drive units and produces a rotation with an output speed for driving the main drive shaft.

Abstract: A power transmission having a four-shaft double planetary gear (I, II), which is driven on the one hand via a turning gear (WG) and on the other via a variable-displacement gear (HG) and is connectable on the power take-off side via selectable ratio gears via controllable clutches (K1A-K7A) to a power take-off shaft (AW3) and is connectable on the power take-off side retroactively via two of the selectable ratio gears (G4, G5) by means of a startup clutch (K0B), as a result of which with the turning gear (WG) disengaged, a fully hydraulic startup range is provided, and the other gear ranges are mechanically-hydraulically split in terms of power when the turning gear is engaged.All the clutches are double claw clutches.The startup clutch has a special construction, with a sliding sleeve.The transmission is especially suitable for agricultural machines, because it is fully reversible. Other versions are shown.

Abstract: A power transmision with a hydrostatically branched variable-displacement gear (HG), a two-stage epicyclic gear (I, II) and a mechanical 8-speed transmission that can be operated in forward and reverse, and with a control system (ST) that triggers the clutches (VV, VR, V0-V8) of the mechanical gear means such that for starting, the variable-displacement gear (HG) is shifted unbranched to the output shaft (ASW) and the clutches are each shifted in a load-free manner, and only on shifting up to 6th gear via the clutch (K5) of the 5th gear and on downshifting to a selectable 4th gear via the 4th-gear clutch (K4) a synchronization of the intermediate shaft (ZW) is effected. Starting and reversing are done by hydrostatically; the efficiency is high; the mechanical transmission factor is approximately 60; synchronization wear is low; and there are only two synchronizing clutches (K4, K5).
