Abstract
An apparatus for controlling weeds and undergrowth by the application of hot water thereto. The apparatus is particularly characterized by its construction including an endless, ground-engaging belt, or apron, disposed immediately aft of the hot water spray. Thus, when hot water is sprayed on the weeds and undergrowth, the sprayed vegetation is not only compressed by the apron, but also heat from the water is retained therein, insulated from ambient conditions by the apron.
