A round baler has a pickup header that is wider than the baling chamber and its inlet so that over-width windrows can be picked up by the machine in spite of its relatively narrower chamber. In order to reduce the width of the crop stream for introduction into the chamber, the machine is provided with a pair of laterally spaced apart, axially aligned, transverse stub augers that engage opposite outboard margins of the stream and converge them inwardly toward the main body of the flow. At the point where the outboard materials are discharged into the central body of the stream, a stuffer mechanism takes control of the stream and charges the materials up into the baling chamber. The augers are driven in such a direction that their front portions rotate down and under the auger shafts so that the outboard crop materials are likewise fed down and under the augers as they are converged toward the center. The inwardly augered materials are released by the augers down at the operating level of the stuffer, contributing to positive, orderly flow of materials through this region and into the baling chamber.

The baler has a twine monitoring assembly which generates a pulsating signal in response to twine being dispensed during bale wrapping operations. The twine is wrapped around the periphery of a monitor wheel and, during dispensing, the twine rotationally drives the wheel. As the wheel rotates, a magnet affixed to the wheel at a location adjacent the periphery thereof, travels past a stationary, magnetically operated, normally open switch thereby briefly closing the switch and temporarily turning on an indicator light until the magnet moves sufficiently far enough away from the switch. During wrapping of the bale, twine is rapidly dispensed, causing the wheel to rapidly rotate and as a consequence, causing the light to pulsate, indicating to the operator that twine is being dispensed.

The bale pusher mechanism of a round baler has a one-way safety breakaway latch between the push bar that engages the ejected bale and the actuator that operates the push bar. During the pushing stroke of the push bar, the latch cannot unlock, but during the return stroke if the push bar hangs up on the bale for any reason, the relief spring of the latch can yield to allow the push bar to disconnect itself from the actuator and remain engaged with the bale. As the baler is driven forwardly a short distance with the tailgate raised, the unlatched push bar rides harmlessly across the top surface of the bale until it completely clears the bale. In most cases the push bar will then easily relatch itself with the actuator by gravity.

A transverse belt guide roll of the baler has its main cylindrical body portion provided with opposite end extremities which are spaced inwardly from the opposite sidewalls of the baler. Reduced diameter stub shafts project outwardly beyond the end extremities and into bearings supported by the sidewalls while the endmost belts along the roll have marginal edge portions which overhang the end extremities of the roll body to thereby eliminate a pinch point for loose residue between the belt edges and the surface of the roll body. Special annular components surrounding the otherwise exposed portions of the shaft ends serve as a shield to prevent the ingress of loose residue into the stub shafts for migration to the bearing assemblies. An alternative embodiment has the overhanging belt margins on one of the idler rolls carried by a vertically swingable belt control arm of the baler.

Quick attachment of crop handling headers to harvesters employs one or more wedge locks, utilizing the mechanical forces thereof to, in turn, tightly and firmly wedge an elongated tongue portion of the header into mating relationship with a header-supporting channel member on the harvester. For fast and easy attachment and release, reciprocable wedge-like latches are jammed into corresponding keepers with progressively increased tightness through use of reciprocable latch shifters readily accessible to the operator at ground level exteriorly of the ends of the header support. An exceptionally strong joint is effected as the latches and their keepers jam the tongue into the channel member.

A round baler includes bale forming mechanism and a crop delivery apparatus for delivering crop material to the bale forming mechanism. A clutch is provided for drivingly disconnecting the bale forming mechanism and delivery apparatus from the driveline while the tailgate is raised to discharge a wrapped bale. Engagement and disengagement of the clutch is controlled by a piston and cylinder assembly, and raising and lowering of the tailgate is controlled by a pair of piston and cylinder units. The baler is provided with a hydraulic sequencing circuit that connects the clutch assembly and the tailgate units to a common source of pressurized fluid. Moreover, the sequencing circuit controls fluid flow to the assembly and the units so that the clutch is disengaged before the tailgate is raised and the clutch is not re-engaged until the tailgate has been closed.

The vertical chamber of the open throat, vertical chamber baler has its bottom inlet opening devoid of a starter roll. A resilient rotary rake tine assembly positioned below and ahead of the inlet opening picks up crop material from the ground and delivers it to a rigid tooth feeder spaced below the inlet opening in vertical alignment therewith. At the beginning of each bale forming cycle when the chamber is small and empty, the rigid tooth feeder propels the crop material into the chamber and against the upwardly moving rear belt stretch which encourages the material to tumble forwardly against the downwardly moving front belt stretch. The oppositely moving surfaces presented by the front and rear belt stretches encourage the tumbling material to coil into a bale core, which ultimately forms a larger bale. In the event loose material drops through the bottom inlet opening during core starting, such material is immediately returned to the chamber by the rigid tooth feeder along with other material delivered to the rigid tooth feeder in the meantime.

A round baler includes a bale shape monitor for facilitating uniform bale formation. The bale shape monitor includes a pair of end sensors and an intermediate sensor. The end sensors sense the diameter of the bale at end locations adjacent opposite ends of the bale, while the intermediate sensor senses the diameter of the bale at an intermediate location spaced between the end locations. The monitor further includes a signal responsive to the sensors to indicate to the operator when the diameter of the bale at one of the end locations is less than the diameter at the intermediate location. The signal is electrically powered and includes a pair of switches, each of which is operably coupled between one of the end sensors and the intermediate sensor to operate an indicator when the diameter of the bale sensed at the corresponding end location is less than the diameter sensed at the intermediate location.

A round baler includes a tension assembly for applying pressure evenly across the periphery of the bale as it grows within the baling chamber. The tension assembly includes a rotatable torque tube extending between the sidewalls and only one tensioning mechanism, such as a hydraulic cylinder, adjacent one of the sidewalls of the baler for supplying a yieldable resistance load in opposition to torsional loads on the torque tube. A load transferring member extends inwardly from the one sidewall to operably connect the single tensioning mechanism to the torque tube at a location spaced between the sidewalls and thereby transfer the loads between the mechanism and tube.

The round baler has a plurality of transverse rolls and a plurality of laterally spaced belts entraining the rolls, wherein the rolls and belts cooperatively define a baling chamber expandable from an initial, generally upright, bale-starting configuration. The baling chamber has a crop intake opening adjacent the bottom of the chamber through which crop material is delivered to the chamber during formation of a bale. The rolls include a lower front roll and a lower rear roll which are located behind the intake opening. The lower rear roll has a bale supporting surface that is positioned generally upwardly and rearwardly from the front roll for supporting the bale during formation thereof at a point spaced upwardly and rearwardly from the intake opening. The belts include a stretch that extends generally upwardly from the front roll when the chamber is in the bale-starting configuration and shifts into engagement with the rear roll as the chamber expands, whereby the belt stretch presents a moving surface extending generally rearwardly and upwardly from the front roll to the rear roll for delivering crop material from the intake opening to the bale.
