[0001] This application claims priority to U.S. Application No. 63 / 775475, filed 21 March 2025, which is incorporated herein by reference in its entirety.TECHNICAL FIELD
[0002] Embodiments of the present disclosure relate to systems and implements for using an adjustable depth tool per row unit to compensate for variability in manufacturing and wear for components of row units of an implement.BACKGROUND
[0003] Implement such as planters are used for planting seeds of crops (e.g., corn, soybeans) in a field. Seeds need to be planted with consistent depth, spacing, and with a high speed to decrease planting time. Consistent uniform planting depth of seed is needed to improve uniformity of emergence by placing seeds into a more consistent seedbed and improving seed-to-soil contact. The seed zone is more likely to dry out when planting too shallow. Cooler soil temperature at deeper depths of the seed increases emergence time.BRIEF DESCRIPTION OF THE DRAWINGS

[0037] All references cited herein are incorporated herein in their entireties. If there is a conflict between a definition herein and in an incorporated reference, the definition herein shall control.Atty Dkt. No.: 25052 / WO
[0038] In order to optimize field production, the delivery of seed (e.g., corn, soybeans, cotton, wheat, sorghum, barley, oats, canola, etc.) into a seed furrow during planting needs to be at a consistent uniform depth among different row units of an implement as the implement performs application passes through a field. Consistent uniform planting depth of seed is needed to improve uniformity of emergence by placing seeds into a more consistent seedbed and improving seed-to-soil contact. Uneven crop emergence limits overall yield potential.
[0039] A depth handle setting determines an opening disc depth relative to gauge wheels of row units (e.g., 8 row units, 16 row units, 24 row units) of an implement to determine a seed planting depth. Wear and manufacturing differences for different components (e.g., disk openers, gauge wheel depth arm, slots in a shank for adjusting the depth handle, etc.) of different row units of an implement can cause seed depth variability across these row units. An operator may set a first group of row units at a first depth setting, a second group of row units at a second depth setting, and possibly a third set of row units at a third depth setting in order to attempt to obtain a uniform seed depth across all row units. Monitoring manufacturing and wear differences in different components of row units that cause differences in actual seed depth between different row units can be difficult to track and remember for implements having a large number of row units (e.g., 8, 16, 24).
[0040] In one embodiment of the present disclosure, an adjustable depth tool having a clamping design compensates for wear and manufacturing differences for different components of different row units in order to allow an operator to set a base positioner of the adjustable depth tool in a same slot position depth setting for all row units of an implement. Depth variations between different row units can be reduced or eliminated by manually adjusting a handle position with respect to the base positioner of the adjustable depth tool. The depth can be set to the same slot position on each row on the entire planter because the variability (e.g., due to wear, manufacturing, etc.) can be zeroed out. This makes it easier to manage the depth setting, especially when a depth change is made due to planting conditions or when changing crops.
[0041] In the following description, numerous details are set forth. It will be apparent, however, to one skilled in the art, that embodiments of the present disclosure may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring the present disclosure.Atty Dkt. No.: 25052 / WO
[0042] FIG. 1 shows an example of a system for performing agricultural operations (e.g., planting operations, fluid application) of agricultural fields including operations of an implement having row units in accordance with one embodiment. For example, and in one embodiment, the system 100 may be implemented as a cloud based system with servers, data processing devices, computers, etc. Aspects, features, and functionality of the system 100 can be implemented in servers, planters, planter monitors, combines, laptops, tablets, computer terminals, client devices, user devices (e.g., device 190-1), handheld computers, personal digital assistants, cellular telephones, cameras, smart phones, mobile phones, computing devices, or a combination of any of these or other data processing devices.
[0043] In other embodiments, the system includes a network computer or an embedded processing device within another device (e.g., display device) or within a machine (e.g., planter, combine), or other types of data processing systems having fewer components or perhaps more components than that shown in Figure 1. The system 100 (e.g., cloud based system) and agricultural operations can control and monitor planting operations for planting within a planting furrow or trench using an implement or machine. The system 100 includes machines 140-1, 142, 144, 146 and implements 141, 143, 145 coupled to a respective machine. The implements (or machines) can include row units having adjustable depth tools for planting operations of crops within associated fields (e.g., fields 103, 105-1, 107, 109). The system 100 includes an agricultural analysis system 122 that includes a weather store 150-1 with current and historical weather data, weather predictions module 152-1 with weather predictions for different regions, and at least one processing system 132-1 for executing instructions for controlling and monitoring different operations (e.g., planting, fertilizing). The storage medium 136-1 may store instructions, software, software programs, etc. for execution by the processing system and for performing operations of the agricultural analysis system 122. In one example, storage medium 136-1 may contain a planting prescription (e.g., planting prescription that relates georeferenced positions in the field to planting parameters (e.g., soil type, downforce, speed, seed orientation, etc.). The implement 141 (or any of the implements) may include an implement 200 whose sensors and / or controllers may be specifically the elements that are in communication with the network 180-1 for sending control signals or receiving as-applied data.
[0044] An image database 160-1 stores captured images of crops at different growth stages and seed at different positions and orientation in a seed passageway during planting. A dataAtty Dkt. No.: 25052 / WOanalytics module 130-1 may perform analytics on agricultural data (e.g., images, weather, field, yield, etc.) to generate crop predictions 162-1 relating to agricultural operations.
[0045] A field information database 134-1 stores agricultural data (e.g., crop growth stage, soil types, soil characteristics, moisture holding capacity, etc.) for the fields that are being monitored by the system 100. An agricultural practices information database 135-1 stores farm practices information (e.g., as-applied planting information (e.g., seed orientation, seed depth, downforce, etc.), as-applied spraying information, as-applied fertilization information, planting population, applied nutrients (e.g., nitrogen), yield levels, proprietary indices (e.g., ratio of seed population to a soil parameter), etc.) for the fields that are being monitored by the system 100. An implement can obtain seed orientation data and provide this data to the system 100. A cost / price database 138-1 stores input cost information (e.g., cost of seed, cost of nutrients (e.g., nitrogen)) and commodity price information (e.g., revenue from crop).
[0046] The system 100 shown in Figure 1 may include a network interface 118 for communicating with other systems or devices such as drone devices, user devices, and machines (e.g., planters, combines) via a network 180-1 (e.g., Internet, wide area network, WiMax, satellite, cellular, IP network, etc.). The network interface includes one or more types of transceivers for communicating via the network 180-1.
[0047] The processing system 132-1 may include one or more microprocessors, processors, a system on a chip (integrated circuit), or one or more microcontrollers. The processing system includes processing logic for executing software instructions of one or more programs. The system 100 includes the storage medium 136-1 for storing data and programs for execution by the processing system. The storage medium 136-1 can store, for example, software components such as a software application for controlling and monitoring planting operations or any other software application. The storage medium 136 can be any known form of a machine readable non-transitory storage medium, such as semiconductor memory (e.g., flash; SRAM; DRAM; etc.) or non-volatile memory, such as hard disks or solid-state drive.
[0048] While the storage medium (e.g., machine-accessible non-transitory medium) is shown in an exemplary embodiment to be a single medium, the term “machine-accessible non-transitory medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and / or associated caches and servers) that store the one or more sets of instructions. The term “machine- accessible non-transitory medium” shall also beAtty Dkt. No.: 25052 / WOtaken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure. The term “machine-accessible non-transitory medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals.
[0049] FIG. 2 illustrates an architecture of an implement 200 for planting operations in trenches of agricultural fields in accordance with one embodiment. The implement 200 (e.g., planter, cultivator, plough, etc.) includes at least one bulk hopper 202 with each bulk hopper containing a seed variety (e.g., a corn seed variety, a soybean variety, etc.). Each bulk hopper is preferably in fluid communication with an individual seed entrainer (not shown). Each seed entrainer is preferably mounted to a lower outlet of the associated bulk hopper 202. Each seed entrainer is preferably in fluid communication with a pneumatic pressure source and configured to convey air-entrained seeds through a plurality of seed lines 204 to the row units 210-217. A controller 260 (e.g., drive controller) is preferably configured to generate a drive command signal corresponding to a desired rate of seed disc rotation for seed meters of the row units. The drive controller 260 is preferably in data communication with a planter monitor of a machine. The implement also includes sensors 250 (e.g., speed sensors, seed sensors 250a-250h for detecting orientation and passage of seed such as sensor systems, downforce sensors, actuator valves, speed sensors for the machine, seed force sensors for a planter, vacuum, lift, lower sensors for an implement, etc.) for controlling and monitoring operations of the implement. The sensors can be utilized on the implement 200 either row-by-row of row units as sensors 250a-250h or upstream of where the seed lines branches out to the row units as illustrated in Figure 2. The sensors 250a-250h can be sensor systems with light arrays or each sensor can include a camera to capture images of seed passing through the seed passageway.
[0050] The row units can include row unit shanks (or shank tails) that are mechanically coupled to the frames 220-227 which are mechanically coupled to a bar 10. Each row unit shank 262a-262h includes slot positions for an adjustable depth tool 270a-270h to manually adjust a seed planting depth for each row unit. In one example, each adjustable depth tool has sufficient precise depth adjustment such that each depth tool is set in the same slot of each row unit even though manufacturing and wear variability exists for different components of each row unit.Atty Dkt. No.: 25052 / WO
[0051] Each row unit can include sensors and components having a seed orientation mechanism (e.g., actuators, air pressure) for obtaining a proper seed orientation and / or positioning of seed during planting in a trench or furrow in an agricultural field. Each row unit may include a respective seed firmer 240-247 for positioning the seed within the trench at a certain depth and also includes a seed orientation functionality to change an orientation of the seed if desired. Each seed firmer can include a first seed vision system (e.g., machine vision, lidar (light detection and ranging)) to determine pre-orientation of the seed after placement in the trench with a seed tube, an actuator to change an orientation of the seed if necessary or desired at least partially based on the pre-orientation data, and a second seed vision system (e.g., machine vision, lidar (light detection and ranging)) to determine a post-orientation of the seed after the seed is positioned and oriented with the seed firmer to confirm that the seed has been orientated with a desired orientation or range of orientations. The row units can include any of the embodiments described herein in conjunction with Figures 2-10.
[0052] FIG. 3 illustrates an embodiment in which the row unit 300 is a planter row unit having adjustable depth functionality of an adjustable depth tool in accordance with one embodiment. The row unit 300 is preferably pivotally connected to the toolbar 14 (e.g., bar 10 of Figure 2) by a parallel linkage 316.

The height of the gauge wheels 348 relative to the opener discs 344 sets the depth of the trench 38 using an adjustable depth tool 382 as positioned within a slot of a shank 380. A depth adjustment rocker 368 limits the upward travel of the gauge wheel arms 360 and thus the upward travel of the gauge wheels 348. A down force sensor (not shown) is preferably configured to generate a signal related to the amount of force imposed by the gauge wheels 348 on the soil 40; in some embodiments the down force sensor comprises an instrumented pin about which the rocker 368 is pivotally coupled to the row unit 300.
[0053] Continuing to refer to FIG. 3, a first seed meter 300-1, is preferably mounted to the row unit 300 and disposed to deposit seeds 42 into the trench 38, e.g., through a seed tube 338 disposed to guide the seeds toward the trench. In other embodiments, the seed tube 338 isAtty Dkt. No.: 25052 / WOreplaced with a seed conveyor or belt. An optional second seed meter 300-2 is preferably mounted to the row unit 300 and disposed to deposit seeds 42 into the same trench 38, e.g., through the same seed tube 338. Each of the seed meters 300-1, 300-2 preferably includes a seed side housing 330-1, 330-2 having an auxiliary hopper 332-1, 332-2 for storing seeds 42 to be deposited by the meter. Each of the seed meters 300-1, 300-2 preferably includes a vacuum side housing 340-1, 340-2 including a vacuum port 342-1, 342-2 pulling a vacuum within the vacuum side housing. Each of the seed meters 300-1, 300-2 preferably includes a seed disc that includes seed apertures (not shown). The seed disc preferably separates interior volumes of the vacuum side housing and the seed side housing. In operation, seeds 42 communicated from the auxiliary hopper 332-1, 332-2 into the seed side housing 330-1, 330-2 are captured on the seed apertures due to the vacuum in the vacuum side housing and then released into the seed tube 338. Each of the meters is preferably powered by individual electric drives 315-1, 315-2 respectively. Each drive is preferably configured to drive a seed disc within the associated seed meter. In other embodiments, the drive 315 may comprise a hydraulic drive or other motor configured to drive the seed disc.
[0054] A seed sensor 350 (e.g., an optical or electromagnetic seed sensor configured to generate a signal indicating passage of a seed, sensor systems, seed sensor having a camera to capture images of the seed passing through a seed passageway) may have multiple sensor arrays that are preferably mounted to the seed tube 338 and disposed to send light or electromagnetic waves across the path of seeds 42. In one example, multiple LED arrays are able to detect orientation of the seed as it passes through the seed tube 338. A closing system 336 including one or more closing wheels is pivotally coupled to the row unit 300 and configured to close the trench 38. An example of seed sensor 350 is described in U.S.Publication No. US20220155214A1.
[0055] In one example, a seed firmer 370 is coupled to a component (e.g., shank 354) of the row unit 300 with a bracket 375. The seed firmer is preferably designed to resiliently engage the bottom of the trench 38 in order to press seeds 42 into the soil before the trench is closed. The seed firmer 370 also includes a seed orientation functionality to change an orientation of the seed if desired or necessary. The seed firmer 370 includes a seed vision system 372 (e.g., machine vision, lidar (light detection and ranging)) to determine pre-orientation of the seed after placement in the trench with the seed tube, an actuator 374 to change an orientation of theAtty Dkt. No.: 25052 / WOseed if necessary or desired which may be based on pre-orientation data, and a seed vision system 376 (e.g., machine vision, lidar (light detection and ranging)) to determine a postorientation of the seed after the seed is positioned and potentially oriented with the seed firmer. The post-orientation data of the seed vision system 376 is used to confirm if the seed has a desired seed orientation. The actuator 374 may include at least one of an airstream and one or more mechanical actuators for orientation of the seed in the trench.
