Abstract

A soil opener has a frog mount adapted to be coupled to a shank or other mounting member of a farm implement. A spreader is removably coupled to the frog mount and includes forward and rearward product delivery channels that are intended to be flow-coupled to product delivery tubes or hoses of the farm implement. A tip is removably coupled to the spreader. The leading edges of the frog mount, the spreader, and the tip, as well as the geometry between these components are such that draft is minimized even when the soil opener is pulled through the soil at higher speeds, e.g., excess of 5 mph. The soil opener may be equipped with an optional soil gathering module.

First claim

We claim:

1. A soil opener engageable with soil, comprising:
a mount configured to be coupled to a shank of an agricultural implement, the mount having a leading edge for separating the soil as the soil opener is pulled through the soil, the mount including at least one delivery channel arranged inside the mount to receive product;
a spreader coupled to the mount and including at least one delivery channel communicating with the at least one delivery channel inside the mount and being configured to deflect product delivered to the spreader outward and rearward into the soil, wherein a first interface angle is defined between a leading edge of the mount and a leading edge of the spreader, and wherein the first interface angle is greater than 10 degrees but less than 20 degrees; and
a tip coupled to the mount and configured to cut a furrow into the soil, and wherein a second interface angle is defined between a leading edge of the tip and the leading edge of the spreader, and wherein the second interface angle is greater than 25 degrees but less than 30 degrees;

wherein the product sequentially flows through the at least one delivery channel of the mount and through the at least one delivery channel of the spreader so as to be discharged from the spreader outward and rearward into the soil.
