A crank-operated packer mechanism includes a crank shaft including crank pins and crank arms. At least some of the crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced. The arms may, for example, be curved or hook-shaped. The crank shaft further includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings.

The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings. The connection further includes a locking feature for locking the connection, such as a locking nut screwed onto a threaded outer end of the crank pins when inserted into the opening. Fixing of rotary bearings onto the crank pins is done by a fixing nut which at the same time serves as a disassembling aid for the spline connection. The crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced about its central rotation axis. Also a baler including the aforementioned packer mechanism.

A baling system comprising a first bale-forming area configured to form a first series of first individual bales, and a second bale forming-area configured to from a second series of second individual bales. The baling system additionally comprises a bale accumulator configured to receive the first and second individual bales from said first and second bale-forming areas and to manipulate the first and second individual bales into a group of four or more bales.

A conveying and collecting device for a crop press has a conveying and collecting unit switchable from a collecting mode into a lifting mode. A first cam track for rotating feed tines of a feed bar is switchable from a fixed state, in which it is stationary and the conveying and collecting unit is in collecting mode, into a moving state, in which it is driven by the conveying and collecting unit that is in lifting mode. A coupling device for operatively coupling the first cam track with the conveying and collecting unit is provided, and a switching device triggers or prevents coupling based on the filling level of the collecting chamber that is detected by a sensor unit. Triggering or preventing of the coupling process is mechanically independent of the detected filling level. A crop press is provided with such a conveying and collecting device.

A square baler comprising a first bale-forming area in which are formed a first series of first individual bales, and a second bale-forming area in which are formed a second series of second individual bales. The square baler additionally comprises a singulator configured to receive the first and second individual bales from the first and second bale-forming areas and to form a single row of the first and second individual bales.

A high capacity square baler including a pickup mechanism configured to pick up a single windrow of crop material off the ground. The baler additionally includes 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 includes one or more stuffer assemblies each configured to push crop generally upward through one of the stuffer chutes. The baler further includes a plurality of separate bale-forming chambers each configured to receive crop material from one or more of the stuffer chutes and to form a bale of crop material therein.

A square baler including a pickup mechanism configured to pick up crop material from a single windrow on the ground, and a rotor configured to receive crop material picked up by the pickup mechanism. The rotor includes a first toothed section, a second toothed section, and an interior auger flighted section located between the first toothed section and the section toothed section. The rotor is configured to separate crop material into two streams of crop material.

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.
