Conservation-tillage grain drills, used in research and commercial production, have been designed mainly for rainfed conditions. A no-till grain drill was fabricated at Colorado State University that can be used for both research and commercial plantings in furrow-irrigated cropping systems. The drill is 4.58 m long, 3.25 m wide, 1~3 m high, and weighs 2200 kg. It has adjustable drive wheels, lift assist wheels, and seed openers to accommodate various furrow row spacings, seed row spacings, and individual seed opener planting depths. The grain drill has the capability to plant alfalfa (Medicago saliva L.), barley (Hordeum vulgate L.), wheat (Trilicum aestivum L. emend. Thell.), oat (Avena sativa L.), soybean [Glycine max (L.) Merr.], dry bean (Phaseolus vulgaris L.), and possibly other seeds. The grain drill has performed well in residue conditions as high as 5 Mg ha⁻¹. Most drill adjustments require ≈lh.
