Abstract

Air drill apparatus for towing behind a tractor and for placing seed or other particulate material in the ground includes wheeled implement mounting bars adapted to be towed behind the tractor, a plurality of air drill assemblies mounted to the implement mounting bars, and a wheeled towed container for the seed or other particulate material to be placed in the ground, the container including a pump for creating a positive air pressure to drive seed or other particulate material therefrom to the air drill assemblies. Each air drill assembly includes an arm pivotally connected to the mounting bar; a thin, circumferentially sharp disc wheel rotatably mounted to the arm at slight angles to the vertical and the direction of travel for cutting a narrow furrow in the ground; a seed boot connected to the container and mounted to the arm adjacent the disc wheel and the ground for depositing seed or other particulate material in the furrow; a seed lock wheel mounted to the arm adjacent and behind the disc wheel for pushing deposited seed or other particulate material deeper into the furrow; and an adjustable depth control wheel mounted to the arm for controlling the depth of furrow cut by the disc wheel.
