Description

Grass drills and seeders consist of seed hoppers, metering devices, and some type of seed placement device. Grass drills range in width from 6 to 15 feet, while grain drills can be up to 40 feet wide. Row spacing varies between 8 and 12 inches, with 12 inches common for rangeland seeding. The metering systems have the capability to deliver 0.5 to 20 lbs of seed per acre. Drills use several different styles of ground-drives to power the metering system. Most drills are towed and use a hydraulic lift mechanism while some drills attach to the tractor’s 3-point hitch. No-till drills use coulters of various sizes and shapes to cut cover-crop residue ahead of the seed-furrow openers. Drills and seeders designed for rangeland are normally extra-heavy duty to withstand the rigors of rough-terrain. A minimum-till drill is available that can seed in rough, non-tilled soil with limited debris.

Application

Cropland drills are applicable for clean-tilled land and do not do well when rocks and debris are present. Rangeland drills are designed with a variety of options to overcome the rigor of rangeland conditions. Seed mixes are commonly used on rangeland. Chaffy and slick seed must be metered separately. Knowledge of the optimum seeding depth of the selected species is important to insure that the correct furrow openers, depth bands, press wheels, and covering devices are used.
