Needham Ag Stainless Steel Seed Brakes are designed to vent most of the air out of the perforated housing, and slow the seed velocity to minimize seeds being blown out of the seed slot. This is especially important when growers are seeding higher rates of seed, or banding fertilizer, as these require high fan speeds to convey the additional material. Its even more important when banding fertilizer using wider seeders, where the fan speed requirements are the highest and the risk of seeds being blown out of the seed slot are the greatest.
The Needham Ag Seed Brakes are made from durable stainless steel and feature 2 mm diameter holes which are designed to retain most seed types, all the way down to canola or rape. These Seed Brakes also feature an angled baffle, which helps reduce seed velocity and minimize seed bunching. Research shows they improve in-row seed spacing by over 2.0 standard deviation points (visit needhamag.com and select the seed brake section for additional statistical information for this product).
Growers claim they have reduced seeding rates when they added The Needham Ag Seed Brakes, because more seeds are placed within the seed slot.
The Needham Ag Seed Brakes are designed to fit on air-seeders which use a 1″ OD secondary hose.
Needham Ag Seed Brakes are shipped with two heavy duty hose clamps.
NOTE, seed brakes with baffles are not recommended with high rates of large seeds, such as peas or chick peas, at rates exceeding around 150 lb/ac on 7.5″ or 10″ spacing.
These seed brakes measure 8″ x 4″ x 1..25″
