Abstract
A manually controlled and operable self-propelled seed bed sterilization system and method is provided for preventing weeds from growth in seed beds. The system includes a wheel driven shuttle vehicle having a hot water reservoir, a hot water applicator manifold housing, a dual-function pump and a controllable valve. A self-contained mobile hot water supply vehicle accompanies the shuttle vehicle and has a water heater with hose connections to the reservoir of the shuttle vehicle to provide a continuous water flow path. The burner of the water heater is controlled to heat the water in the range of about 205-207 degrees F. but below the boiling point of water not to create steam. The shuttle vehicle is displaced over the seed bed at a constant drive speed by an electric motor driven by a gas generator. An operator person guides the shuttle vehicle over the seed bed.
