A baler apparatus has a cylindrical bale-forming chamber defined by a set of compression elements positioned around the circumference of the bale-forming chamber, and drive means configured to drive rotary movement of the compression elements. At least one of the rotary compression elements is configured to provide a reduced level of traction relative to a bale in the bale chamber, as compared to at least the majority of the other rotary compression elements.

An end cap for a spreader roll has a base portion and a pin portion, wherein the pin portion inserts into a bearing mechanism to allow the material spread roll to rotate. The base portion includes a mechanism to prevent wrapping material stretched by the material spread roll from reaching the bearing mechanism.

A module wrapping assembly for a module builder having a first roller rotationally coupled to the module builder about a first axis, a bracket pivotally coupled to the module builder about a bracket axis, and a second roller rotationally coupled to the bracket about a second axis. Wherein, the second axis is offset from the bracket axis. Further wherein, the bracket is pivotable about the bracket axis to reposition the second axis relative to the first axis.

Steered caster wheel systems that include a disengagement system to enable a caster wheel steering mode and non-caster wheel steering mode are disclosed. In some embodiments, the caster wheels are mounted to a subframe that may be independently suspended from the chassis of a vehicle such as a self-propelled vehicle.

A round bale or module building assembly with a frame having a first wall and a second wall separated from one another by a module width and a plurality of rollers positioned between the first wall and the second wall, the plurality of rollers defining at least one belt path. Wherein, at least two rollers of the plurality of rollers have a combined width configured to substantially span the module width.

A round baler for forming a bale of residual product includes a baling chamber, a plurality of press rolls mounted within the baling chamber, and at least one driving bar associated with at least one of the plurality of press rolls. The driving bar extends at least partially along the length of at least one of the plurality of press rolls. The round baler further includes at least one cylindrical portion defined partially along the length of the at least one of the plurality of press rolls. The at least one cylindrical portion is arranged to compensate for a radial extension of the at least one driving bar to define a uniform surface.

A belt-roller arrangement with a deflecting roller and an endless flexible belt and a method for guiding such a belt over such a roller are disclosed. The roller body of the roller includes two deformable roller body segments and a rigid roller body segment part which isin an axial directionpositioned between these two deformable segments. The belt is entirely guided over the central rigid segment part and at least partially over both deformable segments. The belt run is automatically corrected.

A round bale or module building assembly with a frame having a first wall and a second wall separated from one another by a module width and a plurality of rollers positioned between the first wall and the second wall, the plurality of rollers defining at least one belt path. Wherein, at least two rollers of the plurality of rollers have a combined width configured to substantially span the module width.

Disclosed herein is a wrap material feed system of a round baler for forming crop material into a cylindrical bale. The wrap material feed system comprises a first roller, a second roller, a bale formation belt, and a feed pan oriented from a first end adjacent the first roller to a second end adjacent the second roller and a feed pan positioning mechanism oriented to bias the feed pan into engagement with each of the first and second rollers and the bale formation belt. The feed pan comprises one or more runners, at least one guide plate, one or more skid plates, and one or more fasteners comprising a fastener head. The fastener head is positioned at the second end such that a vector representing a first normal force at the second roller intersects the fastener head.

A baler comprising an accelerometer coupled to the frame and configured to output a bulk signal representative of the total vibrational power in the frame, and a controller in operable communication with the accelerometer, where the controller is configured to deconstruct the bulk output signal provided by the accelerometer into at least a first component signal and a second component signal, and where the controller is configured to associate one of the first component signal and the second component signal with a first bearing and the other of the first component signal and the second component signal with a second bearing.
