Abstract
Apparatus for thermally cultivating a field including a wheel-supported vehicle having elongate frame members and a burning chamber over the ground. A draft stack and an air mover are disposed at a forward end of the vehicle and an igniter is disposed beneath the stack. When combustible material is ignited, the air mover is operated to discharge air upwardly through the stack to thereby induce a draft. The induced draft draws air and products of combustion from the burning chamber toward and upwardly through the stack. The forwardly moving fire continuously advances flame against unburned combustible material as the vehicle moves forwardly. The fire is thus continuously propagated. The apparatus additionally includes stowable side sections so that a predetermined vehicle width may be presented for roadway transport.
