<p>The invention relates to a silage-cutting implement with a U-shaped supporting frame which can be attached to a mounting stand and is movable vertically up and down on this and on the rigid supporting- frame legs of which are held on both sides cutting tools movable in opposite directions by driving members and designed as knife-shaped rigid cutting bars. …<??>The new implement is characterised in that, to transmit the driving force from two driving members attached to the end face of the supporting-frame end, there are two levers which are movable forwards and backwards in the direction of the cutting movement about respective fixed pivot pins and by which, via the end arms (12), lying above one another and engaging over one another, of the cutting bars (6, 8), held on a rigid middle piece (7), of the lateral cutting tools, force is transmitted to these which, engaging at their other end on their end arms (12) into the plane, associated with them, of corner connection elements (11), transmit the force, via the force transmission means (13) located in these, to the respective end arms (12) of the front cutting bars (6, 8). Preferably, at the same time, the transmission means (13) consist of metal cylindrical rollers which are arranged vertically in a guide housing and engage in one another by means of arcuate grooves cut in on one side and which transmit shearing forces. …<IMAGE>… </p> |
