Abstract: A pick-up baler for agricultural produce with a compression piston 9 and a rotary conveyor, which rotates about an axis of rotation 18, comprises rakes 21, 22, which have axes 23 extending approximately parallel to the axis of rotation 18 of the rotor, convey the harvested crop through a supply channel 13, can be swiveled about their rake axes 18 under the control of curves and of which at least one acts as a conveying rake 21, the swiveling of at least one further rake, which functions as a supply rake 22, being controllable as a function of the degree of filling of the supply channel 13 in such a manner that, when a specified degree of filling of the supply channel 13 is reached, the harvested crop, collected there, is conveyed over a baling channel inlet opening 12 into a baling channel 11. The supply rake 22 is guided in a curved path 39, which can be moved from a conveying position into a supplying position, whereas the conveying rakes 21 are guided in an immovable curved path 34.

Abstract: A piston type bailer for producing bales of agricultural material comprising a bailing chamber with a reciprocating pressing piston, a crank drive for reciprocating the pressing piston. A feeding element is arranged to feed agricultural material to the bailing chamber. As auxiliary drive changes a position of the feeding element from the crank drive. The auxiliary drive having a first crank unit associated with the feeding element and including a first crank pin rotatably supporting the feeding element, a crank axle and a first crank arm arranged on the crank axle, and a second crank unit associated with the crank drive of the pressing piston and includes a second crank arm driven from the pivot axle of the crank drive and a pivot pin driven by the crank arm.

Abstract: An agricultural baler has a device for picking up stalk-type and blade-type vegetation. The picked up vegetation is inserted into a precompacting chamber wherein it is subjected to initial compacting. The degree of compaction is sensed and, when it reaches a preselected magnitude, the precompacted body of vegetation is expelled from the precompacting chamber into a main compacting chamber. The precompacted bodies are of identical or substantially identical size and density.
