Реферат: 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.
