A ground-opening apparatus for an agricultural implement. The ground-opening apparatus comprises an opening disc for excavating a furrow in the ground, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. The upper bar and the lower bar extend generally in parallel relationship. The lower bar and the rearward bar are joined at a lower, rearward joint. A rotational axis of the opening disc extends through the lower, rearward joint of the support assembly.

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.

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 implement includes a frame carrying a toolbar, and row units coupled to the toolbar. Each row unit includes a tool support and a rotating support coupled to the tool support and configured to rotate about an axis of rotation. Ground-engaging tools are carried by the rotating support and extending outward from the axis of rotation. Rotation of the rotating support about the axis of rotation moves the ground-engaging tools around the rotating support to change which of the ground-engaging tools interacts with the ground. A method of adjusting the agricultural implement includes disengaging the row units from a ground surface, rotating at least one rotating support about a corresponding axis of rotation to move the ground-engaging tools around the rotating support, and re-engaging the row units with the ground surface.

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 system that includes a planter frame. A track and/or wheel couple to and support the planter frame. A first row unit bracket couples to the planter frame. A first offset bracket couples to the first row unit bracket. A first row unit couples to the first offset bracket. The first offset bracket offsets the first row unit from a path of the track and/or wheel.

A planting system for a combine in embodiments of the present invention may have one or more of the following elements: (a) a soil opening system having one or more soil openers operably connected to one or more mounting arms operably attached to the combine, (b) a seed handling system having one or more seed dispensers with one or more seed tubes operably connected to the one or more seed dispensers and a seed reservoir adapted for housing cover crop seed, and (c) a control system having one or more actuators operably connected to one or more controllers, wherein at least one of the sets of soil openers and sets of seed dispensers is operably attached to a header of the combine.

Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative thereto. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches therein, and a transport position, in which the cutting implement is raised above the soil.

The present invention refers to a new adjustment system for mounting and fixing the supports of the planting row units on the toolbars of agricultural implements, which is designed to eliminate possible gaps realized during the assembly and fixing the planting row units on the toolbar. More particularly, the adjustment system is applied to the mounting guides (20a) of the toolbar (20) and is formed by at least one upper mounting assembly (26) and at least one lower mounting assembly (28), which comprise upper (30) and lower (32) support blocks that are associated with said support (24) by fasteners (34), at least one of said support blocks (30, 32) having at least one opening (36) for accommodating an eccentric bushing (38) whose the passing hole (38a) is displaced from the center of said bushing (38).

A soil apparatus is drawn through a furrow and reflectance from the furrow is obtained from the soil apparatus, and a height off target is measured between the soil apparatus and the furrow.
