Apparatus And Method For Furrow Opening Using A Disc
First Claim
1. An apparatus for furrow opening in soil including:
- a first disc having a blade with an outer perimeter that includes a plurality of symmetrical teeth;
a second analogous disc operatively coupled to said first disc; and
wherein said first and second discs are configured to incise and progressively widen a furrow in said soil thereby minimising soil disturbance.

Abstract
There is proposed a novel furrow opening apparatus (10) that includes toothed discs (12 and 14) that are able to penetrate the soil thereby creating a furrow (114). The teeth (20) of the apparatus (10) are configured to prevent hair pinning of plant material within the furrow (114). The edges of the teeth (20) slice any plant material as teeth (20) penetrate the soil. Uncut straw is wedged between the teeth (20) and broken by tension as the discs (12 and 14) diverge and any uncut straw is removed from the furrow (114) by teeth (20). Any soil and plant material that adheres to the teeth (20) is cleared by a scraper (48) and deposited back on the soil surface. The apparatus (10) may further include a seeding device (142) that is configured to follow the toothed discs (12 and 14) and create a seeding furrow (166).

2. An apparatus for furrow opening in soil including:
-
a first disc configured to rotate around a first axis of rotation, said first disc includes a blade outwardly extending from said first axis of rotation, wherein said blade has an outer perimeter includes a plurality of analogous outwardly extending teeth; a second analogous disc operatively coupled to said first disc and configured to rotate around a second axis of rotation, said second disc mirrors said first disc along a central line of symmetry which is substantially parallel to the direction in which said apparatus travels when a furrow is being created; and said apparatus includes a leading edge and a trailing edge, wherein said teeth of said first and second discs are in closer proximity at said leading edge than at said trailing edge.

16. A method for creating a seed furrow in soil using a furrow opener having a first and second disc, said method includes the steps of:
-
moving said furrow opener across the surface of said soil, whereby said furrow opener incises the surface of said soil; and allowing said first and second discs to rotate, wherein said first and second discs are configured to incise and progressively widen said furrow as said furrow opener is moved over the surface of said soil. - View Dependent Claims (17)
