An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

A planting machine for forming a trench for planting seeds and/or fertilizer in a ground surface, including a frame that supports a planting assembly having a cutting tool and a gauge that sets the height of the cutting tool so as to determine a depth of the trench formed by the tool, wherein the assembly includes a linkage coupled between the frame to the gauge and an actuator to allow for remote adjustment of the linkage, in order to vary a planting depth of the trench.

A system for monitoring the levelness of a multi-wing agricultural implement may include a central frame section, a wing section pivotably coupled to the central frame section and a field contour sensor configured to generate data indicative of a contour of an aft portion of the field located rearward of the implement relative to a direction of travel of the implement. The system may further include a controller communicatively coupled to the field contour sensor. The controller may be configured to monitor the data received from the field contour sensor and assess a levelness of the implement based at least in part on the contour of the aft portion of the field.

An apparatus for connecting an implement to a three point hitch of mobile machinery comprises two frameworks, a first framework and a second framework. The first framework is disposed in a first plane and comprises at least two parallel, vertically-spaced apart, laterally extending rails. There are three attachments supported by the first framework for attachment to the three-point hitch. The second framework is slidable generally in the plane of the first framework and is mounted on the rails to slide laterally along the rails. At least two connectors are supported by the slidable second framework for connecting the second framework to an implement that can be pulled or pushed by the mobile machinery. A driver is connected to the first framework and connected to the second framework for driving the second framework laterally back and forth along the rails of the first framework.

An agricultural implement has a ground opening and closing assembly that readily allows for adjustment of a pair of closing disks into different, discreet or infinitely variable, home positions that vary in height, disk spacing and fore/aft dimension. In one form, a pair of disk mounts have a pair of mounting receptacles for each support arm. Each support arm is configured to be inserted into one of the receptacles to set the height and fore/aft position of the associated closing disk. Mounting openings can be formed in the disk mounts and the support arms, and a simple pin mechanism received in aligned mounting openings can effect manual disk adjustment without tools. The disk mounts and the support arms can have multiple mounting openings spaced apart differently from the ground opening member to vary the spacing between the closing disks.

The present invention relates to a head for attaching an agricultural tool to a support beam configured to be towed along a longitudinal axis, the support beam extending substantially transversely to the longitudinal axis, said head including a mounting bracket assembly configured to mount to the support beam at a location along a length of the support beam, and enable attachment of the agricultural tool such that the agricultural tool, when attached, suspends from the clamped mounting bracket assembly, the mounting bracket assembly being mountable to the support beam such that a tool attachment portion of the mounting bracket assembly is forwardly disposed, enabling the agricultural tool to be attached at a fore or central position along the longitudinal axis relative to the transverse support beam, or rearwardly disposed, enabling the agricultural tool to be attached at the central or an aft position along the longitudinal axis relative to the transverse support beam.

Apparatus and associated methods relate to a two-position quick-connect mounting system for mounting a farm implement to a toolbar in an operating configuration, the mounting assembly including a toolbar bracket and an implement bar, the implement bar being mounted to the toolbar bracket by: i) raising the implement bar into a downward facing cavity of the toolbar bracket; and ii) longitudinally translating the implement bar such that lateral projections on either side of the implement bar are received into operating slots in the toolbar bracket, and a spring-biased locking member automatically engages a securing member. In an illustrative embodiment, the implement bar may be mounted to the toolbar bracket in a stowage configuration by sliding the projections into stowage slots separate from the operating slots. In some embodiments, the implement may advantageously be mounted in one of two mounting configurations, without requiring tools.
