A baler twine tension control assembly including a displacement detector and elements defining a twine path. The twine path enters and exits the twine tension control assembly and within the twine tension control assembly extends across a first fixed location and a second fixed location as well as across an intermediate displaceable location located between the first fixed location and the second fixed location. The displacement detector is connected to the intermediate displaceable location and generates a signal indicative of the displacement of the displaceable location.

A twine tension relief assembly for a baler including a tension detection apparatus for detecting the tension in a line of twine, a biased cutting element displaceable between a first retained position and a second released position and an actuator adapted to cause the biased cutting element to move from the first retained position to the second released position in response to a signal issued by the tension detection apparatus. The practical application includes when the tension in a strand of twine exceeds a predetermined threshold, the tension detection apparatus causes movement of the biased cutting element so that a strand of twine passing though the twine tension relief assembly is severed and damage to the knotter mechanism and its component parts is avoided.

A baler twine tension measurement assembly including a displacement detector and elements defining a first twine path. The first twine path extends between a first location and a second location which is angularly displaceable with respect to the first location. The displacement detector operates to generate a signal indicative of the angular displacement of the second location with respect to the first location.

A knotter drive apparatus for a baler includes a knotter gear drive shaft having a drive shaft axis and a shaft outside diameter. A plurality of knotter assemblies are mounted on the knotter gear drive shaft. Each assembly includes a first knotter gear sector including a first sector hub portion and a first sector radial portion. The first sector hub portion includes a central passage at least partly defined in the first sector hub portion for receiving the knotter gear drive shaft. The first sector radial portion extends radially outward from the first sector hub portion relative to the drive shaft axis, and has defined thereon a plurality of intermittent gear tooth segments. The first sector hub portion has a circumferential gap defined therein greater than the shaft outside diameter such that the first knotter gear sector is removable radially, relative to the drive shaft axis, from the knotter gear drive shaft.

A tying device for an agricultural crop press has a drive unit for driving the tying device and a work unit for processing crop which is switchable from a coupled state, in which it is coupled to the drive unit and driven, into a decoupled state, in which it is not coupled to the drive unit and not driven. The work unit has a pawl and the drive unit has a coupling device with which the work unit and the drive unit are operatively connectable. The coupling device interacts in the coupled state of the work unit with the pawl. The drive unit has an electromagnetically acting switch that is switchable reversibly from an inactive into an active state and that is configured to trigger or to terminate the operative connection of the coupling device with the pawl. An agricultural crop press is provided with such a tying device.

A baler includes: a bale forming channel, a reciprocating plunger configured to compress bale material in the bale forming channel to form a bale, and a binding system for binding a bale in the bale forming channel with a pair of twines that pass around opposite sides of the bale. The binding system includes a knotter that includes a rotary bill hook, a twine holder, a twine cutter and a stripper element. The bill hook includes a catching element that is configured to adopt an open configuration to release a retained twine from the bill hook after a knot formed by the knotter is removed from the bill hook by the stripper element, so that the cut end of the twine is not pulled through the knot. The catching element is moved to the open configuration by an opening element that acts against the resilient biasing element, without rotating the bill hook beyond the second position.

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 knotter assembly is used with a baler and configured to form knots in strands of a binding material used to secure a formed bale. The knotter assembly has a rotatably driven knotter disc, a rotary billhook driven by the knotter disc, and a twine disc assembly positioned adjacent the billhook for holding strands of binding material in position for engagement by the billhook. The billhook includes a billhook casting forming a platform, and a billhook tongue connected at a pivot point with the billhook casting. The platform has a first raised lip and a second raised lip forming a channel therebetween configured to receive the billhook tongue so as to firmly grasp the binding material. An upper surface of the first raised lip extends above an upper surface of the second raised lip.

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.
