    FUNDAMENTALS
    [001] The present description refers to an agricultural baler having a compression system to form crop bales. Balers typically include a mechanical trigger, such as a connection system or cable system, to mechanically initiate the supply of a crop flake to the compression system. Such mechanical triggers often include preloaded moving parts, which retract in response to the cultivation load, and can clog, requiring manual intervention. SUMMARY
    [002] In one aspect, the description provides a baler having a compression system to form a bale, and a feeding system having a packaging mode for accumulating the crop in a pre-compression chamber and a lifting mode for transporting cultivation for the compression system. The baler also includes a sensor array having at least one sensor that generates a signal, the at least one sensor being coupled to the supply system. The signal corresponds to a cultivation load on the feeding system. A control unit is configured to receive the signal from the sensor array and initiate the elevation mode based on at least the signal.
    [003] In another aspect, the description provides a control system for a baler. The baler has a compression system to form a bale, a feeding system having a packing mode to accumulate the crop in a pre-compression chamber and a lifting mode to transport the crop to the compression system, an arrangement of sensor including at least one sensor that generates a signal, the at least one sensor being coupled to the supply system. The control system is configured to receive the signal from the sensor array corresponding to a cultivation load on the supply system and initiate the lift mode based on at least the signal.
    [004] In yet another aspect, the description provides a method of controlling a baler. The method includes receiving a signal from a sensor attached to a feeding system having a packaging mode to accumulate cultivation in a baler pre-compression chamber, where the signal corresponds to a cultivation load on the feeding system , and initiates a lifting mode to transport the crop to a baler compression system to form a bale based on at least the signal.
    [005] Other aspects of the description will become more apparent by considering the detailed description and attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

    [0010] Before any description modalities are explained in detail, it should be understood that the description is not limited in its application to the details of the formation and the arrangement of components exposed in the following description or illustrated in the attached drawings. The description is capable of supporting other implementations and can be practiced or performed in several ways. Directions, such as clockwise and counterclockwise, used here are for illustrative purposes only.
    [0011] The description refers to a machine, such as a baler 10. In the illustrated implementation, the description refers to a square baler to form bales 12 of cultivation 14, such as wheat. In other implementations, the description may refer to other types of balers, such as other extrusion-type balers or non-extrusion-type balers, round balers, etc. In still other implementations, the description may refer to other types of machinery, for example, vehicles, tractors, harvesters, other types of agricultural machinery, forestry machinery, mining machinery, construction machinery, manufacturing machinery, etc.
    [0012] With reference to figure 1, the baler 10 includes a frame 16 supported by wheels 18 for displacement along a support surface 20, such as the field or the road. The frame 16 defines a longitudinal direction L generally in the direction of travel of the baler 10 and a direction of width W substantially perpendicular to the longitudinal direction L and defined as substantially parallel to the support surface 20. A tow bar 22 is affixed to the frame 16, it generally extends in the longitudinal direction L, and is connectable to a towing vehicle (not shown), such as a farm tractor or other driven vehicle. The baler 10 also includes a power take-up shaft 24 that can be connected to the towing vehicle to transmit a rotary drive force from the towing vehicle to various components of the baler 10, such as the components that collect crop 14 and form bales 12, which will be described in more detail below. In other implementations, baler 10 may have a dedicated power supply and / or driving machine (not shown), such as a motor, engine, battery, fuel cell, etc., to drive wheels 18 and to drive and / or energize the various components of the baler 10.
    [0013] With reference also to figure 3, the baler 10 includes a feeding system 26 for capturing crop 14 from the surface and transporting crop 14 to a compression system 28 (see figure 1) to be formed in bale 12. The compression system 28 compresses the crop 14 (for example, by means of a plunger or belt) to a densely packed shape, such as a square or round bale. In the illustrated implementation, the feed system 26 includes a collection set 30 that defines an inlet 32 for receiving the crop 14 from the surface. The pickup set 30 includes a roll deflector 34 generally oriented in the width W direction for picking up crop 14 and placing crop 14 in baler 10. Pickup set 30 includes a pickup plate 36 disposed adjacent to the roll deflector 34 to transport crop 14 towards a cutting set 38. The pickup plate 36 may include a continuous loop surface, for example, a movable conveyor, driven to transport crop 14, or other appropriate mechanisms. The cutting set 38 includes an elongated cutting axis 40 generally oriented in the width W direction and supporting a series of cutters or blades 42 to cut the crop 14. Cutting set 38 rotates about a central axis A of the axis cutter 40, the central geometric axis A being generally oriented in the direction of width W substantially parallel to the roller deflector 34. In other implementations, the pickup set 30 and cutter set 38 may have different constructions and orientations with respect to the baler 10 and with respect to each other.
    [0014] With reference to figures 2 and 3, the feeding system 26 also includes a lift assembly 44 having a feeding pan 46 and separators 83 that cooperate with the collection set 30 and the cutter set 38 to receive the cultivation 14 from the cutting set 38. The feed pan 46 and the separators 83 define a pre-compression chamber 48, along with any side walls (not shown) that generally extend from the feed pan 46 in the direction towards the separators 83. In the illustrated implementation, the pre-compression chamber 48 has a mechanical movement mechanism 50 arranged therein to react to the cultivation load in the pre-compression chamber 48 and move the elevator assembly 44 on a lifting stroke, the which will be described in more detail below. In some implementations, the pre-compression chamber 48 does not have the mechanical movement mechanism 50. In the illustrated implementation, the feed pan 46 is substantially curved in the shape of an arc; however, in other implementations, the feed pan 46 may have other curved shapes or may be straight. The pre-compression chamber 48 (for example, the feed pan 46) includes an approximate midpoint 118, a half upstream 114, upstream from the approximate midpoint 118, and a half downstream 116, downstream from the midpoint approximately 118, all in relation to the direction of the cultivation movement through the pre-compression chamber 48 in the direction towards the compression system 28.
    [0015] The elevator set 44 also includes a loading fork 56 that cooperates with the feed pan 46 and movable through the feed pan 46 inside the pre-compression chamber 48 to pre-compress the crop 14, thus increasing the load in the pre-compression chamber 48. The loading fork 56 includes a fork element 58 coupled to a drive shaft 60 by a loading fork link system 62. The drive shaft 60 can be rotated about a stationary drive geometry axis D for driving the fork element 58 along a packaging path 64 and a lifting path 66, as shown in figures 2-4. The fork element 58 includes a fork bar 68 having an elongated shape and which generally extends in the width W direction. The fork element 58 also includes a plurality of forks 70 extending from the fork bar 68 in the direction for the feed pan 46. In other implementations, the fork element 58 can have other shapes and configurations to sweep the crop 14. The fork element 58 is rotatably coupled to the loading fork connection system 62 in an element joint fork 72. The loading fork connection system 62 includes a plurality of arms 74, at least one of which is interconnected between the fork element 58 and the drive shaft 60.
    [0016] A loading fork connection system 62 is operable in a packaging mode and a lifting mode. In the packaging mode, a loading fork connection system 62 assumes a packaging configuration, in which the fork element 58 is driven through the packaging path 64 in a packaging stroke. In the lifting mode, a loading fork connection system 62 assumes the lifting configuration, in which the fork element 58 is driven through the lifting path 66 in the lifting stroke. The packaging path 64 forms a first continuous mesh, in which the fork element 58 passes through the feed pan 46 from a receiving end 76 adjacent the cutting assembly 38 (i.e., the beginning of the packaging path 64 ) towards the supply end 78 adjacent to the compression system 28, exits the feed pan 46 at an intermediate point 80 between the receiving end 76 and the supply end 78, and returns to the receiving end 76 to begin again. The lifting path 66 forms a second continuous mesh, which may be larger than the first continuous mesh (as shown in the illustrated embodiment), in which the fork element 58 passes through the feed pan 46 from the receiving end 76 adjacent to the cutting assembly 38 towards the supply end 78 adjacent to the compression system 28. On the lift path 66, the fork element 58 exits the feed pan 46 at an outlet point closest to the supply end 78 , and closer to the compression system 28, than the intermediate point 80 On the packaging path 64 and then returns to the receiving end 76. In some implementations, the fork element 58 can enter the compression system 28, for example , a bale chamber to be described below, in the lifting stroke.
    [0017] Thus, in the packaging path 64, the fork element 58 directs the cultivation 14 from the cutter assembly 38 to the feed pan 46 and compresses the cultivation 14 in the pre-compression chamber 48. In the elevation path 66, the fork element 58 carries the crop 14 to the compression system 28. The load of the crop carried to the compression system 28 in the lifting stroke is called a flake. In addition, the loading fork 56 can be referred to here as the filler, particularly with reference to the initiation of the lifting mode.
    [0018] In other implementations, the feeding system 26 may include other structures and configurations, such as those known in other types of balers, such as round balers.
    [0019] The compression system 28 includes a plunger plunger (not shown) to compress crop 14, a bale chamber 84 to receive and shape compressed crop 14, and a bale box or extruder 86 to compress and dispense / extrude the compressed culture 14 in the form of a bale 12. The bale chamber 84 is arranged adjacent to the supply end 78 of the feed pan 46 to receive a cultivation charge, i.e. the flake, from the pre-compression chamber 48. Generally, in the packaging mode, the fork element 58 packs culture in the pre-compression chamber 48 and, in elevation mode, the fork element 58 raises the culture from the pre-compression chamber 48 and raises the culture into the bale chamber 84. The plunger (not shown) is configured for reciprocating movement in the bale chamber 84 to compact and compress the crop 14 in the bale chamber 84 in each lifting stroke. In the illustrated implementation, the bale chamber 84 has a rectangular cross section to form square or rectangular bales; however, in other implementations the bale chamber 84 may have other cross sections and configurations. When the bale 12 is formed, the bale 12 is packaged from the bale chamber 84 into the bale box 86, from which the bale 12 is extruded and / or released. Between the bale chamber 84 and the bale box 86, a knotting assembly (not shown) dispenses, wraps, cuts, and ties twine threads around the bale 12 in response to a bale length sensor (no shown), such as a star wheel, when a predetermined bale length is reached.
    [0020] In other implementations, the compression system 28 may include other structures and configurations, such as those known in other types of balers, such as round balers.
    [0021] The baler 10 includes a sensor array 88 having one or more sensors of the same or different types. The sensor array 88 is electrically coupled to a control unit 112 having a memory storage device 90 and a data manipulation device 92. The sensor array 88 transmits data in the form of an electrical signal or signals to the memory unit. control 112, which, in turn, transmits an electrical signal or signals to a display device 104 (figure 1) and to the components of the baler 10 to control the components of the baler 10, as will be described in more detail below. More specifically, control unit 112 includes input and output circuits, a programmed processor or microprocessor (e.g., data manipulation device 92) and memory (e.g., memory storage device 90). The display device 104 may include a screen, such as a liquid crystal display (LCD), a light emitting diode (LED) display, a cathode ray tube (CRT) display, a nanotube display, a audio display including a speaker, or similar.
    [0022] In one implementation, sensor array 88 includes a sensor 94 associated with loading fork 56 to detect a cultivation load or F1 force (figure 4), applied to fork element 58 and generate data in the form of a signal or value representative of the force, effort, or torque on, or the deflection of a component of a loading fork 56. For example, sensor 94 may include a force cage applied to a component of the loading fork 56, such as the fork bar 68 (as shown in figure 2), the loading fork connection system 62, the drive shaft 60, a portion of a loading fork connection system 62 or arm adjacent to the fork bar 68, a portion of a loading fork link system 62 or arm adjacent the drive shaft 60, a pickup hook 96, any combination of these locations, or other indicative loading locations (eg, force, torque) applied to the fork 58.
    [0023] Additionally or alternatively, sensor 94 can be positioned to monitor a load on the power outlet axis 24 to detect the crop load or force, or in those implementations with a dedicated power supply or driving machine, a load (for force, torque, current load, etc.) associated with it.
    [0024] Sensor array 88 may include, in addition or alternatively, a sensor 98 associated with cutter set 38 to detect crop load or force on cutter set 38 and generate a signal or value representative of crop load or force on the cutting set 38.
    [0025] In addition, the sensor arrangement 88 may additionally or alternatively include a sensor 108 associated with the pre-compression chamber 48 (i.e., a component that defines the pre-compression chamber 48, such as the pan feed 46), to detect cultivation load or contact force F2 that affects one or more of the components that define the pre-compression chamber 48, for example, usually normal to one or more components. For example, sensor 108 can also be arranged on the side walls (not shown) that define and enclose the pre-compression chamber 48 from the sides and / or on the separators 83 that define and enclose the pre-compression chamber 48 from the top. Sensor 108 can also be coupled to mechanical movement mechanism 50. In some implementations, sensor 108 is positioned closer to the approximate midpoint 118 of the feed pan 46 (or generally of the pre-compression chamber 48) than to the end supply 78. For example, sensor 108 may be in the upstream half 114 of pre-compression chamber 48.
    [0026] As another example, sensor 108 may be closer to the receiving end 76 of the feed pan 46 than to the approximate midpoint 118 of the pre-compression chamber 48. As yet another example, sensor 108 may be exactly for less than halfway between the approximate midpoint 118 and the supply end 78 of the pre-compression chamber 48. In still other implementations, the sensor 108 may be in the downstream half 116 of the pre-compression chamber 48.
    [0027] Sensor 108 generates data in the form of an electrical signal or value representative of the cultivation load or contact force F2 that falls on the component that defines the pre-compression chamber 48, such as the feed pan 46. For For example, sensor 108 may include a contact pressure sensor, such as a load cell, a force cage, a movably mounted load plate, etc., coupled to the base, sides, top of the feed pan 46, or another component defining the pre-compression chamber 48. Sensor 108 may also include a mobile-mounted device for measuring the contact force F2 by measuring the deflection of the mobile-mounted device.
    [0028] In other implementations, the sensor array 88 may additionally or alternatively include other types of sensors to detect the cultivation load or force, such as a contact pressure sensor, for example, a contact pressure plate, for detect the impact of cultivation 14 on a surface. The sensor array 88 may include one or more contact pressure sensors, coupled to various components of the feed system 26, such as the forks 70, for example, to one or more of the forks 70, the feed pan 46, the roller deflector 34, pickup plate 36, or other components in direct or indirect contact with the crop 14. The contact pressure sensor can be configured to directly or indirectly measure the force of the crop 14 that affects one or more components baler 10, for example, usually normal to the component.
    [0029] In still other implementations, the sensor array 88 additionally or alternatively includes a humidity sensor 100 to detect humidity or humidification and generate a humidity signal, indicative of the humidity or humidification of the crop 14 or of the air within any part of the baler 10. The humidity sensor 100 can be arranged in communication with the feed pan 46, for example, in, or adjacent to, the pre-compression chamber 48, as shown in figure 2. In other implementations, the humidity sensor 100 can be positioned in other locations where the crop 14 can be found, such as the pickup set 30, the cutter set 38, the fork element 58, the bale chamber 84, the bale box 86, etc.
    [0030] In some other implementations, the sensor array 88 may additionally or alternatively include other types of sensors to detect other parameters and conditions, for example, temperature. In still other implementations, other types of sensors (for example, electronic, mechanical, optical, piezoelectric, Hall effect, magnetic, electromagnetic, etc.) can be used.
    [0031] Sensor array 88 can include any combination of one or more of any of the sensors discussed here.
    [0032] The sensor array 88 can additionally also take other measurements such as time, displacement, and distance which are useful for other calculations, such as distance traveled, time, bale time, average speed, bale creation and completion location of the bale, duration of bale creation, distance traveled by the bale, flakes by bale, courses by bale, relation between course and flake, bale length on the left, bale length on the right, fork load, cultivation humidity, etc. , which is collected and stored in memory storage device 90. The data can be manipulated by the data manipulation device 92, and the data and / or the manipulated data can be displayed on the display device 104 in real time, and / or after the data is collected. For example, the data can be stored and then downloadable for processing after the baling operation. The display device 104 can be arranged in or on the towing vehicle and / or the baler 10, and can also include one or more auxiliary display devices 104, used after the data is transferred to other devices.
    [0033] The control unit 112 is operatively coupled to the supply system 26 and operable to control the packaging and lifting modes of the elevator assembly 44 based at least in part on the signal or signals from the sensor assembly 88. The signal or signals from sensor assembly 88 are electrical signals carried by wire or wirelessly to the processor of control unit 112, which, in turn, controls the packaging and elevation modes of elevator set 44 at least in part by sending a electrical signal or signals carried by wire or wireless to control the lift assembly 44. For example, control unit 112 controls an actuator (not shown) that moves the pickup hook 96 in and out of the packaging position, in that a loading fork moves in the packaging path 64 (packaging mode) and an elevation position, in which a loading fork moves in the lifting path 66 (lifting mode). In other implementations, as opposed to the sensor assembly 88 sending an electronic signal to move the loader fork into lifting mode, the baler 10 may include a hydraulic or pneumatic system, which could trigger the lifting mode based on balance of force, for example, the catch hook 96 can be moved between the lifting position and the packing position based on the balance of force.
    [0034] More specifically, control unit 112 is operable to initiate elevation mode in response to the signal or signals, for example, in response to an increase in cultivation load in the feed system 26, as measured by the sensor array 88. Even more specifically, the control unit 112 is operable to initiate the lift mode in response to an increase in cultivation load in the pre-compression chamber 48, for example, the feed pan 46, based on a reading the signal or signals from the sensor assembly 88. Even more specifically, the control unit 112 is operable to initiate the lift mode in response to an increase in cultivation load in the pre-compression chamber 48 at a more close to the approximate midpoint 118 of the pre-compression chamber 48 than to the supply end 78. Even more specifically, still, the control unit 112 is operable to initiate the lift mode in response to an increase in cul load in the upstream half 114 of the pre-compression chamber 48. Even more specifically, still, the control unit 112 is operable to initiate the lift mode in response to an increase in cultivation load in the upstream half 114 of the chamber precompression 48 closer to the receiving end 76 than the approximate midpoint 118.
    [0035] In some implementations, the control unit 112 bases the initiation of the elevation mode on the signal or signals from sensor 94 associated with a loading fork 56. Thus, the control unit 112 initiates the elevation mode when the cultivation load, or the cultivation mass, in the pre-compression chamber 48, increases and / or reaches a predetermined level. In other implementations, the control unit 112 bases the initiation of the elevation mode on the signal or signals from the sensor 108 associated with the pre-compression chamber 48. Thus, the control unit 112 initiates the elevation mode when the load of culture, or the culture mass, in the pre-compression chamber 48 increases and / or reaches a predetermined level. In still other implementations, the control unit 112 bases the initiation of the elevation mode on signals from both sensor 94, associated with a loading fork 56, and sensor 108 associated with pre-compression chamber 48. Thus, the control unit 112 initiates the elevation mode when the cultivation load, or the cultivation mass, both on a loading fork 56 and in the pre-compression chamber 48 increases and / or reaches predetermined levels, respectively. The signals from sensors 94, 108 can be used together to refine the calculated cultivation load. Thus, the accuracy of the crop load calculation is improved when using signals from two sensors. Also, signals from any two or more of the sensors in the sensor arrangement 88 described above can be used to refine the calculated cultivation load and thus initiate the elevation mode based on a refined cultivation load calculation. In addition, control unit 112 can specifically use the signal or signals from sensor 94 when sensor 94, which is associated with mobile loading fork 56, is moving in the downstream direction.
    [0036] In some implementations, the lifting mode is initiated when the cultivation load on a loading fork 56 and / or in the pre-compression chamber 48 increases by a predetermined amount during the start of the packaging stroke. That is, the control unit 112 can use the signal or signals from sensor 94 and / or sensor 108 when sensor 94 and / or sensor 108 is positioned closer to the approximate midpoint 118 of the pre-compression chamber 48 than to the supply end 78, it is either positioned at or close to the upstream half 114 of the pre-compression chamber 48, or it is positioned closer to the receiving end 76 than the approximate midpoint 118.
    [0037] Cultivation humidity can also be considered by the control unit 112 when determining when to start the lift mode.
    [0038] In still other implementations, the control unit 112 bases the initiation of the elevation mode on a signal or signals from any one or more of the sensors in the sensor array 88. Thus, the control unit 112 initiates the mode of elevation when the cultivation load, or the cultivation mass, in the feeding system 26 increases and / or reaches a predetermined level, and / or when the cultivation humidity reaches a predetermined level. Predetermined levels can be selected, pre-programmed, and / or adjusted based on the type of cultivation and conditions.
    [0039] In operation, the roller deflector 34, the cutter shaft 40, the drive shaft 60 of a loading fork 56, the plunger, etc., are finally activated or energized by the tractor vehicle by means of the power outlet 24, or by the dedicated power supply or driving machine in other implementations. Catchment set 30 receives crop 14 from the surface and transports crop 14 to cutter set 38, which cuts crop 14 and feeds crop 14 to lift set 44. Lift set 44 compresses crop 14 inward from the pre-compression chamber 48 during the packaging mode and then raises and transports the crop 14, now the flake, into the bale chamber 84 during the elevation mode, thus transporting the crop 14 to the compression system 28. The elevation mode is initiated, or triggered, when the control unit 112 determines that the predetermined level of cultivation load and / or humidity has been reached in the pre-compression chamber 46. In some implementations, the elevation mode is initiated when the control unit 112 determines that the predetermined level of cultivation charge has been reached in front of the pre-compression chamber 48, for example, in the upstream half 114. Then, the plunger of the compression system 28 compresses the bale forming flake in the bale chamber 84. When the bale length sensor determines that the bale 12 has reached the predetermined length, the knotting devices tie the string around the bale 12 and the bale 12 is extruded through bale box 86 when the next bale is formed behind it.
    [0040] The sensors 94, 98, 108 measure a load currently applied to a loading fork 56, and / or the cutting set 38, and / or the pre-compression chamber 48, and / or the compression system 28 by cultivation 14, and are therefore indicative of the mass of cultivation 14. The data is manipulated using the data manipulation device 92 to determine a value that corresponds to the cultivation mass through a baler 10, for example, the flow in mass through the elevator assembly 44 and pre-compression chamber 48, and / or the mass flow through the cutting assembly 38, and / or the mass flow through the capture assembly 30.
    [0041] For example, the cultivation load F1 on the fork element 58 during a portion or all of the lifting stroke can be integrated, added, or otherwise manipulated by the data handling device 92 on at least a portion of the sweep course (i.e., a portion of the lift path 66, where the forks 70 are arranged substantially within the pre-compression chamber 48 in an upward stroke for raising the crop 14 from the receiving end 76 to the supply end 78 and into the bale chamber 84) to provide a value or output 106 that corresponds to the bale flake mass. The time can also be recorded and a corresponding time coupled with each mass data point, which, in turn, can be processed by the data manipulation device 92 to calculate the mass flow rate.
    [0042] The contact force F2 can additionally or alternatively be processed by the data manipulation device 92 to calculate and / or refine the mass data. In some implementations, signals from sensor 94 and sensor 108 are used together to generate the mass data; however, other signals that come from any single sensor or any combination of sensors in sensor array 88 can be used to generate the mass data.
    [0043] The humidity sensor 100 data can additionally be processed in the data manipulation device 92 to further refine the mass output 106, taking into account the variations that can be attributed to the humidity or humidification of the crop 14 or to the air . For example, excess moisture can cause crop 14 to jam, which can influence the F1 force on fork element 58. In addition, wet cultivation has a portion of its mass attributed to water. By taking into account the moisture levels of crop 14 in the data manipulation device 92, the data can be manipulated to obtain a more accurate calculation of the mass of crop 14 as a dry crop.
    [0044] In addition, multiple load sensors can work to provide multiple load signals to the data handling device 92. The multiple load sensors could work redundantly, or as checks against each other, etc., to increase the accuracy and reliability of the mass output 106, and alone or in combination with the humidity sensor 100, time, temperature, etc. Likewise, multiple sensors of other types, such as the types described above, can similarly be applied in any combination to the data manipulation device 92 to increase the accuracy of the output 106.
    [0045] As such, several sensors from sensor array 88 can be employed to collect data that can be used to determine or approximate the mass crop flow through a baler 10. In some of the implementations described above, the flow in Cultivation mass, or cultivation load, is measured with essentially static sensors, or fixed sensors that do not move substantially in relation to the baler assembly structure. As such, the risk of clogging is reduced by eliminating moving parts and / or retractable parts.
    [0046] Thus, the description provides, among other things, a detection apparatus and method for determining a value associated with the crop mass, and a method for initiating a filling gait cycle to transport a crop flake to the system of compression, the method being based on the cultivation load detected by the sensor array. Although the above describes example modalities of the present description, these descriptions should not be viewed in a limiting sense. On the contrary, there are several variations and modifications that can be made without departing from the scope of the present description.

    [0002]
    2. Baler (10) according to claim 1, characterized by the fact that the signal is a first signal, in which the sensor arrangement (88) includes a second sensor (94, 98, 99, 108) coupled to the pre-compression chamber (48) generating a second signal corresponding to a cultivation force in the pre-compression chamber (48) generally normal to the pre-compression chamber (48), in which the control unit (112) is configured to initiate elevation mode based on at least the first and second signals.
    [0003]
    3. Baler (10) according to claim 2, characterized by the fact that the second sensor (94, 98, 99, 108) is arranged on at least one of a feed pan (46), a wall, or a separator (83) defining the pre-compression chamber (48).
    [0004]
    4. Baler (10) according to claim 2, characterized by the fact that the control unit (112) is configured to initiate the lift mode based on at least an increase in the first and second signals.
    [0005]
    5. Baler (10) according to claim 2, characterized in that the pre-compression chamber (48) includes a supply end (78), a midpoint (118), and a receiving end ( 76) in relation to the direction of the cultivation movement towards the compression system (28), in which the second sensor (94, 98, 99, 108) is arranged closer to the midpoint (118) than to the end of supply (78).
    [0006]
    6. Baler (10) according to claim 5, characterized in that the second sensor (94, 98, 99, 108) is generally disposed between the midpoint (118) and the receiving end (76)
