Abstract: An opener mounts on a tool supporting shank of an agricultural seeding implement for forming a furrow-type opening in the ground and delivering product into the ground as the agricultural seeding implement is displaced across the ground in a forward working direction. The opener includes a mounting body secured to the shank and a lower leg forming a knife that penetrates into the ground at an offset angle from vertical to minimize soil disturbance while seeding. The leading face of the lower leg and the front face of a lower portion of the mounting body each define a blunt edge (i) extending upwardly and rearwardly along a height thereof at a longitudinal slope, and (ii) extending in a widthwise direction across a majority of a width between the two side surfaces at a lateral slope that is between 60 degrees and 90 degrees from the forward working direction.

Abstract: A furrow opener has an opener body with a mounting portion for mounting onto one of the tillage tool supporting shanks of an agricultural implement. A tip body that forms a furrow in the ground is supported on the opener body at a location which is downwardly and forwardly in relation to the mounting portion of the opener body. A product delivery passage on the opener body connects to a product delivery tube of the implement for delivery of a product therethrough into the furrow formed by the tip body. The tip body is coupled to the opener body so as to be adjustable in height relative to the opener body between a plurality of different mounted positions corresponding to different heights relative to the product delivery passage. One or more spacers may be mounted between cooperating faces on the opener and tip bodies in some of the mounted positions.
