drill

A farm implement for planting seeds which forms a small furrow, deposits the seed in dribbles, covers the seed, and packs soil over it. It can also deposit fertilizer, lime, or other amendments into the soil, alone or with the seed. Machines with multiple-row seeding units that are each suspended from a main frame; use volumetric displacement type meters, place the seed in rows, and typically have on-row packing. They have a main frame which supports a common seed hopper and seed metering for all rows. Metered seeds free-fall through individual delivery tubes to the point of deposition in each row behind each ground opener; ground openers can be disc-type or hoe-type openers.
