First Claim
1. A furrow opener for mounting on an agricultural implement shank for movement therewith in a forward working direction, the furrow opener comprising:
- an opener body including a shank mount arranged to support the opener body on the implement shank and a forward connecting portion;
a tip body comprising;
a rear connecting portion at a rear side of the tip body arranged for connection to the forward connecting portion of the opener body so as to couple the tip body to the opener body adjacent a bottom end of the opener body;
a furrowing portion extending downwardly and forwardly from the rear connecting portion beyond the bottom end of the opener body so as to be arranged to form a furrow in the ground;
a guard portion extending upwardly from the furrowing portion along a front side of the opener body;
an upper connecting portion comprising a hook member extending upwardly and forwardly from a top end of the opener body;
the upper connecting portion being spaced above the rear connecting portion; and
a retainer member supported on the opener body adjacent a top end of the tip body such that the upper connecting portion of the tip body above the rear connecting portion is arranged to be received between the retainer member and the opener body adjacent the top end of the tip body;
the retainer member comprising a depending portion extending downwardly and rearwardly in mating engagement over the upper connecting portion of the tip body ahead of the opener body such that the upper connecting portion of the tip body is arranged to be inserted between the depending portion of the retainer member and the opener body by rotating the furrowing portion of the tip body downwardly and rearwardly towards the bottom end of the opener body; and
the rear connecting portion of the tip body and the forward connecting portion of the opener body being shaped so as to be arranged for mating connection subsequent to alignment of the upper connecting portion with the retainer member as the furrowing portion is rotated downwardly and rearwardly towards the bottom end of the opener body.

Abstract
A furrow opener comprises an opener body including a shank mount arranged to support the opener body on an agricultural implement shank for movement in a forward working direction and a tip body readily separable from the opener body and arranged for forming a furrow in the ground in the working direction. The tip body includes a furrowing portion extending downwardly and forwardly beyond the opener body so as to be arranged to form the furrow in the ground. A retainer member is supported on the opener body to retain a portion of the tip body adjacent the top end thereof on the opener body to provide support to the tip body against a moment acting on the tip body from the rearward force on the furrowing portion during furrow formation.

20. A method of mounting a tip body on an opener body of a furrow opener in which the opener body comprises a shank mount arranged to support the opener body on an agricultural implement shank for movement therewith in a forward working direction, and in which the tip body comprises a rear connecting portion coupling the tip body to the opener body adjacent a bottom end of the opener body, a furrowing portion extending downwardly and forwardly from the rear connecting portion beyond the bottom end of the opener body, and a guard portion extending upwardly from the furrowing portion along a front side of the opener body, wherein there is provided a forward connecting portion on the opener body connected to the rear connecting portion of the tip body so as to be readily releasable, one of the connecting portions comprising a socket and the other one of the connecting portions comprising a protrusion matingly received within the socket;
- the method comprising;
providing a retainer member supported on the opener body adjacent a top end of the tip body spaced above the rear and forward connecting portions; aligning an upper connecting portion of the tip body above the rear connecting portion with the retainer member on the opener body; inserting the upper connecting portion of the tip body between the retainer member and the opener body adjacent the top end of the tip body by rotating the furrowing portion downwardly and rearwardly towards a bottom end of the opener body; and mating the forward connecting portion and the rear connecting portion as the furrowing portion is rotated downwardly and rearwardly towards the bottom end of the opener body subsequent to alignment of the upper connecting portion of the tip body with the retainer member on the opener body.
- the method comprising;
