Seed boot
First Claim
1. A seed boot for attachment to a shank and shovel assembly of a ground opener comprising in combination a hollow body portion including a front wall, a rear wall, side walls, a substantially cylindrical seed tube connector at the upper end of the body and having a cross-sectional area of the body portion, and a seed discharge formed at the lower end of said body portion, said seed discharge including said front wall extending below the lower end of said rear wall this portion of the front wall flaring outwardly and rearwardly upon each side of the longitudinal centre line of said front wall to form a shroud, means within said seed discharge to divide same into a pair of side by side outwardly directed discharge openings, at least one deflector step situated within said body portion on one of said front and rear walls to equalize distribution of seed passing therethrough regardless of the angle of entry of said seed tube attached to said boot and at least one air vent formed through the rear wall of said boot, a pair of vertically spaced apart deflector steps, one on said front wall and one on said rear wall, said one air vent being situated just below said deflector step on said rear wall.

Abstract
A seed boot for air seeders includes a cast hollow body having a relatively narrow cylindrical upper end intake into which a seed tube may be clamped. Vertically spaced apart transverse ribs or steps are situated one on the front wall and one on the rear wall of the interior of the body to equal distribution of the seed regardless of the angle at which the tube enters the boot. Spreaders may be secured to the bottom or discharge end of the boot and can be used to adjust the spread pattern of the seed and an air release slot or vent is provided in the rear wall of the body to reduce air pressure thus reducing the speed at which the seed strikes the ground thereby reducing bounce. A rear strut may be provided at the rear of the boot to accommodate a banding knife if desired, to permit seeding and fertilizer banding in one operation.
