A row unit for a seeding machine. The row unit includes a frame, a first gauge wheel arm pivotally coupled to the frame, a first gauge wheel coupled to the first gauge wheel arm, a second gauge wheel arm pivotally coupled to the frame, a second gauge wheel coupled to the second gauge wheel arm, and a position sensor assembly having a position sensor at least partially disposed between the first gauge wheel arm and the second gauge wheel arm such that the position sensor is at least partially concealed from view between the first and second gauge wheels when viewing the row unit along an axis of rotation of the first gauge wheel.

Systems, methods and apparatus are provided for monitoring soil properties including soil moisture, soil electrical conductivity and soil temperature. Embodiments include a soil reflectivity sensor and/or a soil temperature sensor for measuring moisture and temperature.

Systems, methods and apparatus for monitoring soil properties and applying fertilizer during a planting operation. Various sensors are disposed in ground engaging components for monitoring soil properties. The ground engaging components may have structure for opening a side trench in the sidewalls of the seed trench and may include liquid application conduits for injecting liquid into the sidewalls of the resulting side trenches.

An agricultural seeder has furrow opener assemblies spaced along a width of the implement frame. Each furrow opener assembly has an opener arm pivotally attached to the implement frame, and a furrow opener attached to the opener arm. A product delivery system delivers agricultural products to the furrow opener assemblies, and a product control controls the product delivery system such that agricultural products are delivered only to active furrow opener assemblies. A bias force system is operative, when activated in a transport mode, to exert an upward bias force on the active and idle furrow opener assemblies, and operative, when activated in an operating mode, to exert a downward bias force on the active furrow opener assemblies, and to exert substantially no force on the idle furrow opener assemblies.

A seed-sowing assembly, especially of rice, consisting of at least two single seeding units arranged in parallel and displaced longitudinally from each other, which allows a narrow separation between furrows, wherein each of said single units comprises a first pivoting support arm connected at one of its ends that supports a load regulator; and a second pivoting support arm connected to another end of the first support arm that supports at least one furrow-generating disc; at least one depth limiting wheel coupled to at least one furrow-generating disc; a seed contact wheel; and a third pivoting support arm connected to one end of the second support arm that supports two furrow-closing wheels. A seed-sowing machine comprising the seed-sowing assembly.

A mounting assembly for a gauge wheel on a row unit allows for infinite lateral adjustment of the gauge relative to an opening disc on the row unit. The mounting assembly includes an arm with a threaded bore extending through a split end of the arm. A threaded bushing is adjustably mounted in the bore and secured in a desired position with a bolt standing through the split end to clamp bushing in position. The split end mounting arm provides a method of quickly and easily adjusting the lateral position of the gauge wheel on the row unit in infinite increments.

In one aspect, a system for monitoring seedbed floor conditions within a field may include a frame and a wheel coupled to the frame. The wheel may be configured to support the frame relative to a soil surface of the field as the frame is moved across the field. The system may also include a support arm pivotably coupled to the frame and a disc coupled to the support arm, with the disc configured to penetrate the soil surface of the field and roll relative to a seedbed floor within the field. Furthermore, the system may include a sensor configured to detect pivotable motion of the support arm relative to the frame. As such, the pivotable motion of the support arm may be indicative of variations in a profile of the seedbed floor as the ground engaging assembly is moved across the field.

A laterally movable carrier is associated with a row frame. The carrier is connected to a frame member, an opener, a first outlet and a second outlet to allow for dynamically variable adjustment of the lateral separation between a first row of planted seed and a second row of planted seed, where the first row of seed is adjacent to the second row of seed.

An apparatus and system for adjustably controlling the position and depth of row closer wheels in no-till planting applications, the apparatus comprising a frame, a piston movably secured at the top to the frame, upper and lower parallel arms disposed about the piston and movably secured at one end to the frame and at the other end to a hub stem, and a set of piston arms each movably secured at the top to one of the upper or lower parallel arms and at the other end to the bottom of the piston. A closing wheel assembly having a closing wheel frame and a set of closing wheels pivotally mounted to a lever on a single axle assembly allows the operator to change the angle at which the closing wheels intersect the ground surface during use. Accordingly, as the angle of the lever is manipulated, the angle of the closing wheel pivotally mounted to that lever changes in the vertical and/or horizontal dimensions.

The present invention involves an adjustment mechanism for seed or grain drill planters which allows for the adjustment of the camber and/or toe of individual coulters on the planter.
