A seed drill is:
Drilling is the term used for the mechanized sowing of an agricultural crop. A typical seed drill consists of a hopper of seeds arranged above a series of tubes that can be set at selected distances from each other to allow optimum growth of the resulting plants. Arranged in front of the tubes are a series of knife blades known as coulters. In operation, the seed drill is dragged forward to allow the coulters to cut open the soil, with a metering mechanism on the hopper periodically allowing a number of seeds to fall into the tubes, and through them into the freshly cut soil. The result is a set of spaced seeding locations, which can then be covered by a built-in rake.
Advantages of Drill Seeding:
The seed drill allows farmers to sow seeds in well-spaced rows at specific depths at a specific seed rate; each tube creates a hole of a specific depth, drops in one or more seeds, and covers it over. This invention gave farmers much greater control over the depth that the seed was planted and the ability to cover the seeds without back-tracking. This greater control meant that seeds germinated consistently and in good soil. The result was an increased rate of germination, and a much-improved crop yield.
Our seed drill made by John Deere and is 14 feet wide. We drill approxamatly 2,000 acres annually for seed production. Our drill seeding rates range from $10.00 to $50.00 per acre depending on the project size.
