Abstract: A baler including a binding system including a twine holder including a first rotary disk including a first clamping notch forming a first knot and a second clamping notch forming a second knot, the depth of the second notch being greater than that of the first notch, a retainer adjacent a periphery of the first rotary disk, a clamping plate cooperating with the retainer to hold the twines and a drive system rotating the first rotary disk to clamp twine located in at least one of the clamping notches against the retainer. The retainer applies a greater clamping force on the twines located in the first notch than those located in the second notch. When the twines are located in the second notch, the first rotary disk rotates the twines beyond an end of the clamping plate, thereby releasing the twines from the clamping plate and the retainer.

Abstract: A cutter device for an agricultural harvester, including: a rotor with a plurality of tines; a sub-assembly including a pivot shaft, a knife, and a first bottom plate located beneath the rotor in a working condition; a support frame; a positioning device mounted to the support frame, and a control mechanism mounted to the support frame. The sub-assembly is moveably mounted to the support frame and is arranged to move relative to the support frame in a lateral direction that is transverse to the forward moving direction of the cutter device between i) a working position in which the sub-assembly is aligned with the support frame in a manner that enables the knife to be engageable by the positioning device, and ii) a maintenance position in which the knife is laterally spaced apart from the positioning device and the sub-assembly protrudes laterally outwards from the support frame.

Abstract: A cutter device for an agricultural harvester comprises a rotor with a plurality of tines, a knife that is adjustable between a cutting position and a non-cutting position, and a positioning device that controls movement of the knife. The positioning device is adjustable between (i) a first position in which it positions the knife in the cutting position, (ii) a second position in which it positions the knife in the non-cutting position, and (iii) a third position in which it is disengaged from the knife to allow movement of the knife independently of the positioning device. The positioning device is configured to engage the knife and prevent significant movement of the knife independently of the positioning device when the positioning device is in the first position and at intermediate positions between the first position and the second position.

Abstract: A cutter device for an agricultural harvester includes: a rotor with a plurality of tines, the rotor being rotatable to transfer agricultural crop along a feed path; a knife, the position of the knife being adjustable; a bottom plate located beneath the rotor, the feed path being located between the rotor and the bottom plate, and the bottom plate including an opening through which the knife extends when in a cutting position; a control mechanism including a control element which is movable between primary and secondary positions. The control element control movements of the knife between a first position in which the knife is in a cutting position in the feed path, a second position in which the knife is substantially out of the feed path in a non-cutting position, and a third position in which the knife is located at an intermediate position between the cutting and non-cutting positions.

Abstract: A binding apparatus for a baling machine includes a dispensing mechanism for dispensing at least two strips of binding film and guiding the strips of film simultaneously onto the surface of a rotating bale. The dispensing mechanism lays the strips of film side-by-side on the bale surface to form a combined strip having a width greater than the width H of each individual strip of binding film.

Abstract: A baler apparatus includes a baling chamber including a channel including an inlet end and an outlet end, a reciprocating plunger adjacent the inlet end of the baling chamber that is operable to compress a body of bale material within the baling chamber, a binding device for binding the compressed body of bale material to form a bale, and at least one adjustable wall for adjusting the compression of the bale material during formation of a bale.

Abstract: A plunger press produces compressed bales of forage, straw, biomass or fibrous mass for agricultural and/or industrial use. The press includes a bale case, a reciprocating plunger structure, at least one material feeding duct laterally leading into a material charge feeding section of the bale case, and at least one plunger structure drive mechanism. The plunger structure compresses respective material charges fed from the feeding duct into the bale case. The plunger structure is subdivided perpendicularly to a reciprocation direction of the plunger structure in the bale case into at least two structurally separated compression surfaces. Each of the compression surfaces is smaller than a cross-section area of the bale case. The compression surfaces are driven substantially parallelly in the reciprocation direction and with a time shift in relation to each other to alternatingly compress material on partial surfaces of the cross-section area.

Abstract: A cutting unit for agricultural machines, including a rotor carrying on a base body spaced apart tine arrangements with circumferential phase shifts between adjacent tine arrangements. Each tine arrangement includes at least one tine with a base secured to the rotor base body and an outwardly protruding triangular tine tip forming a conveying flank leading in the rotor rotation direction and extending from the tine end to a transition into the base. A cutting unit bottom forms a lower boundary of a conveying channel. Cutting blades protrude from the cutting unit bottom through the conveying channel besides moving paths of the tine tips. Scrapers are placed in a conveying direction through the conveying channel behind the rotor. A compression surface provided at the base of the tine ahead of the conveying flank in the rotor rotation direction gradually ascends at least substantially up to the transition into the conveying flank.

Abstract: In a plunger press (P) for producing compressed bales, the plunger press (P) comprising a bale case (1) accommodating a linearly reciprocating plunger structure (11), a material feeding duct (9) laterally leading into the bale case (1), and a plunger structure crank mechanism (14) driven by a drive source, the plunger structure (11) compressing a respective material charges (23) fed into the bale case (1) against a material strand (4) of at least one already compressed material charge, and linearly stepwise shifting the compressed material strand (4) in the bale case by overcoming a back pressure of the material strand, the plunger structure (11) having at least two structurally separated compression surfaces (A1, A2) each being smaller than a cross-section area (A) of the bale case (1), the compression surfaces (A1, A2) being parallelly driven in the linear reciprocation direction and relative to each other with a time shift (T).

Abstract: A method of applying stretch film wrapping to an agricultural bale (10) which is of rectangular cross section and using a bale wrapper apparatus which comprises: a table which supports the bale (10) and which operates to rotate the bale generally about its longitudinal axis (11) during a wrapping cycle; a dispenser reel arrangement (12, 13, 16, 17, 20, 21, 24, 25) from which stretch film wrapping is withdrawn so as to form successive overlapping windings of film which cover the bale; and means which applies relative rotation between the table and the dispenser reel arrangement about a second axis (14) which extends substantially perpendicular to said first axis during the wrapping cycle; in which: each winding of film includes a longitudinal edge strip portion and an adjoining longitudinal strip portion; and the longitudinal edge portion has different deformation properties from the deformation properties of said adjoining portion so as to be more readily extensible under a given load than said adjoining port
