A gauge arm (and concomitant method of retrofitting an existing gauge arm) comprising an arm portion, a receptacle portion for receiving two or more sealed bearings, and two or more sealed bearings inserted into the receptacle portion. The receptacle portion is smooth bore, with the sealed bearings being press fit into same. The sealed bearings can be of different dimensions, such as one being a gauge wheel and closing wheel bearing, and one a round bore grain drill bearing. The receptacle portion then comprises a stop within the bore thereof.

An agricultural implement, such as an agricultural seed planter, includes a number of ground engaging row units. The row units receive seed and/or other particulates and deposit the seed or particulates to the ground. The row unit can include row cleaners to aid in allowing a coulter or disk to create a furrow in a field. The seed is metered via a seed metering system and deposited in the furrow. A closing system closes the furrow after the seed has been deposited. To aid in access and mounting of the seed meter, it can be connected without connection to side components of a frame. In addition, the row cleaner and closing system can include mounting systems that allow better results and easier access to the same and other portions of the row units.

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.

A disc assembly for an agricultural implement includes a mounting assembly having a housing and a rotatable shaft disposed within the housing. The rotatable shaft includes a recess extending along a portion of an axial extent of the rotatable shaft. The recess is formed by an inner surface of the rotatable shaft. The rotatable shaft also includes a first engagement feature formed on the inner surface and a key disposed about the recess. The key is configured to engage an opening of a disc blade to block rotation of the disc blade relative to the rotatable shaft. Furthermore, the disc assembly includes a fastener having a shaft configured to extend through the opening of the disc blade and to engage the recess of the rotatable shaft. The shaft has a second engagement feature configured to engage the first engagement feature to couple the disc blade to the rotatable shaft.

A disc assembly for an agricultural implement includes a mounting assembly having a housing and a rotatable shaft configured to be disposed within the housing. The mounting assembly includes a first end cap non-movably coupled to the rotatable shaft, in which the first end cap is configured to engage a longitudinally inward surface of a first disc blade. The mounting assembly also includes a second end cap having a first engagement feature configured to selectively engage a second engagement feature of the rotatable shaft to non-movably couple the second end cap to the rotatable shaft. The second end cap is configured to engage a longitudinally inward surface of a second disc blade, and the second end cap is selectively removable from the rotatable shaft via disengagement of the first and second engagement features to facilitate engagement and disengagement of the rotatable shaft with the longitudinal passage of the housing.

A disk assembly for agricultural implements comprises a disk hanger including a proximal end and a distal end opposite the proximal end. The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.
