The particle belt is configured to receive a particle, to accelerate the particle at the particle acceleration section, and to expel the particle toward a trench in soil. The particle delivery system includes a first hub assembly engaged with the particle belt at a first location and a second hub assembly engaged with the particle belt at a second location. The particle acceleration section is disposed generally at the first location, a substantially no-slip condition exists between the first hub assembly and the particle belt at the first location and between the second hub assembly and the particle belt at the second location, and the first hub assembly and the second hub assembly are configured to stretch the particle belt at the particle acceleration section to accelerate the particle.

This document discloses a row unit (2) for feeding granular material to the ground. The row unit has a seed furrow-opener, which has a seed furrow-opening arm (21) carrying a seed disc (22). The seed furrow-opening arm has a proximal portion, in which the seed furrow-opening arm is pivotable about a first geometrical axis (Rb) and a distal portion, to which the seed disc is rotatably attached. The row unit has a depth regulator, which has a depth-regulating arm (31) carrying a gauge wheel (32). The depth-regulating arm (31) is pivotable about a second geometrical axis (Ra) which is concentric with a centre of rotation for the seed disc. The row unit comprises a first adjusting device for setting the height of the gauge wheel (32) in relation to the seed disc (22). The first adjusting device comprises a lever (34), which is fixedly connected to the depth-regulating arm, a depth-regulating driver arm (36) pivotable at the first geometrical axis, and a control link (35), which connects distal portions of the lever (34) and the depth-regulating driver arm (36), so that the pivotal position of the lever is controllable by pivoting the depth-regulating driver arm. The document also discloses agricultural implements comprising such row units and methods for operating agricultural implements.

In one aspect, a system for providing downforce control includes a seeder including a plurality of row units. One or more actuators are operably coupled with the plurality of row units and configured to adjust a downforce of the plurality of row units. A sensor is configured to detect one or more seeding parameters. A computing system is configured to control the operation of the plurality of row units. The computing system is further configured to receive an input associated with a target depth range of the row unit into an underlying field, receive data related to one or more seeding parameters, receive data related to an actual seeding depth; generate a command signal based on a differential between the actual seeding depth and the target depth range; and generate a force command for the one or more actuators to adjust a downforce of the plurality of row units.

A pallet raising apparatus for raising a pallet of bags to a desired height adjacent to an air seeder includes a vehicle with a load bed, and a raising stand positioned at a rear end of the load bed. A pallet deck supports the pallet, and the entire pallet is raised and lowered to a convenient height adjacent to an agricultural product applicator. Additional features allow the apparatus to raise large bags of agricultural products as well.

A tow head for agricultural implements, particularly those intended for the distribution of seeds, composts, fertilizers, herbicides, pesticides, or fungicides in the field, is designed to promote a structural reinforcement that heightens resistance and, accordingly, improve the conditions of operation of these agricultural equipment. More particularly, a tow head for agricultural implements is formed by a telescopic center bar from which angularly designed sidebars are projected from the coupling end, and which are connected to the respective side wings of the structural chassis of the agricultural implement, and the sidebars are endowed with a reinforcement that is fixed along at least part of the longitudinal length of each sidebar.

Systems and method for retaining a downspout onto a spout are disclosed. The downspout may be retained on the spout using hook and loop fasteners. In some implementations, a portion of a spout may include a first portion of a hook and loop fastener and the downspout may include a second portion of the first hook and loop faster. The first and second portions of the hook and loop faster are complimentary such that the first and second portions of the hook and loop fastener combine to interlocking secure the downspout and the spout together.

A plurality of different controllers on an agricultural machine are time synchronized. A positioning system detects a geographic location and a timestamp, which is indicative of a time when the geographic location was sensed, is applied to the geographic location. A first controller, that identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, generates a future timestamp indicating a future time at which the action is to be taken. An action identifier (that identifies the action) and the future timestamp is sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the future timestamp based upon the future timestamp, a current time, and the actuator delay.

This document shows a seed furrow opener, comprising a seed furrow opener arm (22), and a pair of seed discs (25) rotatably connected to the seed furrow opener arm (22) via at least one shaft unit (24). Each of the seed discs (25) has a respective geometric rotational axis. The rotational axes are non-parallel to each other, so that a mutual distance between the peripheries of the seed discs (25) is non-constant. The seed furrow opener has a continuous cut-out (221) formed in the seed furrow opener arm (22) for mounting the shaft unit (24), a slot (2221, 2222) extending from the cut-out (221) to a periphery (220) of the seed furrow opener arm (22), and a clamping device (224a, 224b; 225a, 225b), arranged to compress the slot (2221, 2222), so that the shaft unit (24) is clamped in the cut-out (221). The document also shows a row unit (2, 2a-2f) comprising such a seed furrow opener, an agricultural implement (1) comprising a plurality of such row units, a method for manufacturing a seed furrow opener arm (22) and a method for mounting a seed furrow opener.

An agricultural row unit includes a soil-engaging tool supported from a pivot arm. A sensor generates an output signal relating to an orientation of the pivot arm relative to a frame member. An actuator is configured to applying a down pressure on the soil-engaging tool. A control system in signal communication with the sensor is responsive to the generated output signal to effect a change in applied down pressure on the soil-engaging tool by the actuator. The soil-engaging tool may be a closing wheel or a flap. One or more additional sensors may be provided on gauge wheel arms of the row unit with the control system being responsive to output signals of the additional sensors to effect the change in applied down pressure on the soil-engaging tool by the actuator.
