A baler implement includes a lower passage wall defining a lower boundary of a pre-compression passageway. The lower passage wall includes a forward portion and an access panel. A pivotable connection interconnects the forward portion and the access panel at a lower and forward transverse edge of the access panel such that a rearward and upper transverse edge of the access panel moves vertically to provide access into the pre-compression passageway. Access is obtained from the rear of the baler implement, between the rearward transverse edge of the access panel and a bottom wall of the compression chamber, without the access panel hanging down from the compression chamber and obscuring access into the pre-compression passageway.

A conveyor for a baler has a feed bar with first and second bar parts connected by a coupling such that, from a stop position, the bar parts are rotatable relative to each other in a rotational direction against a restoring force and coupled to each other in the stop position to prevent rotation in opposite rotational direction. The conveyor conveys crop within a collection chamber toward a press chamber in collection mode and from the collection chamber into the press chamber in feed mode by feed tines of the first bar part. The conveyor guides the first bar part in collection mode by a feed collection lever of the second bar part and by force transmission via the coupling and guides the first bar part in feed mode partially by a feed lever of the first bar part by rotating the bar parts relative to each other.

A square baler comprising a gear box configured to receive power from a rotating power source. The baler additionally comprises first and second drive shaft sections extending outwardly from generally opposite sides of the gear box. The gear box is configured to rotate said first and second drive shaft sections using power from the rotating power source. The baler further comprises first and second reciprocating plungers respectively coupled to the first and second drive shaft sections in a manner such that rotation of the first drive shaft section causes reciprocation of the first plunger and rotation of the second drive shaft section causes reciprocation of the second plunger.

A baler for hay, straw, grass, and similar feed materials is provided. The baler communicates compressed material from a vertically inclined compression passage formed in-between opposing conveyer belts to a central area of a baling chamber for baling. A plunger within the baling chamber can reciprocate in two directions to form bales which are tied and discharged from both ends of the baling chamber.

An agricultural baler including a bale chamber; a plunger; a feeder duct; and a rotor feeder unit. The rotor feeder unit includes a rotor feeder unit bottom distant from a rotor feeder forming a lower boundary of a conveying channel through the rotor feeder unit. The rotor feeder unit also includes scrapers placed in a conveying direction behind the rotor feeder. The scrapers extend in between the tines and have a leading face cooperating with the tines. The agricultural baler further includes a position adjuster configured to displace the leading face of the scrapers relative to the rotor feeder unit bottom, and to displace a top wall and/or the bottom wall of the feeder duct, in order to adjust the volume of the feeder duct.

A high capacity square baler comprising a pickup mechanism configured to pick up a single windrow of crop material off the ground. The baler additionally comprising one or more stuffer chutes each configured to receive at least a portion of the crop material picked up by the pickup mechanism. The baler additionally comprising one or more stuffer assemblies each configured to push crop material generally upward through one or more of the stuffer chutes. The baler additionally comprising a plurality of bale-forming chambers each configured to receive crop material from one or more of the stuffer chutes. The baler further comprising a plurality of knotter assemblies each associated with one of the bales forming chambers and each configured to wrap and tie securement lines around each formed bale. The knotter assemblies are configured to operate independently of one another, such that formed bales can be tied at different times.

An agricultural baler including a bale case, a plunger, a duct, and a stuffer unit, operably associated with the duct. The stuffer unit includes a fork assembly including tines, a drive mechanism acting on the fork assembly, and a clutch arrangement for selective coupling the drive mechanism to a power source of the baler. The clutch arrangement includes a selectively operable dog clutch including a driving clutch member and a driven clutch member. The driving and the driven clutch member are configured for selectively engaging each other in one direction of rotation of the driving clutch member relative to the driven clutch member. The clutch arrangement furthermore includes an overrunning clutch associated with the driving clutch member and the driven clutch member.

A baling system operable to receive loose material, form the loose material into an individual charge, and compress the individual charge with one or more other charges to form a bale. The baling system includes a forming chamber and a plunger operable to move in a reciprocating manner within the forming chamber from a front-dead-center position in which a plunger face is furthest re) from the bale to a rear-dead-center position in which the plunger face contacts and compresses the bale. The system includes a feeder component operable to pre-compress the loose material to form the individual charge and then move the individual charge into the forming chamber, the feeder component including a feeder chute having a feeder chute outlet connected to the forming chamber. The feeder component is operable to pre-compress the loose material into the individual charge and then move the individual charge into the forming chamber for compression by the plunger into the bale. The system includes a moisture sensor operable to determine a moisture content of the individual charge in the feeder chute, wherein at least a portion of the moisture sensor is positioned in the plunger face. In one embodiment, the moisture sensor is a near infra-red sensor operable to use near infra-red radiation to determine the moisture content.

A baler having a frame, a feed system coupled to the frame, a baling chamber for receiving crop from the feed system, and a plunger assembly reciprocally compressing the crop. The baling chamber defines an extrusion axis therethrough. The plunger assembly is at least partially positioned within and movable with respect to the baling chamber. The plunger assembly has at least a first plunger motion aligned with the extrusion axis. The baler also includes a feed system cap having at least a first cap motion aligned with the extrusion axis, the first cap motion being synchronized with the first plunger motion. At least one of the plunger assembly and the feed system cap has a second motion that is not aligned with the extrusion axis.

A baler (10) has a stuffer chute assembly (22) with upper and lower curved walls (44, 46) forming a stuffer chamber (24). A rear portion (54) of the upper wall (44) extends downwardly and forwardly from a baling chamber (12) and a forward portion (50) extends above an inlet opening to the stuffer chamber (24). The upper wall (44) has a plurality of laterally spaced-apart wrappers (52, 56), with adjacent wrappers forming slots (70, 72) extending generally from said crop receiving inlet opening to an outlet opening (48) for cooperation with tines (40) of a feeding mechanism (36). The wrappers (52, 56) are movable relative to the lower wall (46) at a forward end (60) and at a rearward end (66) of the upper wall (44) so as to change a cross-sectional dimension of the stuffer chamber (24). The baler (10) has a forward wall adjusting mechanism (80) for setting a forward end (60) of the upper wall (44) in a predetermined position, and a rear wall adjusting mechanism (110) for setting a rear end (66) of the upper wall (44).
