摘要： A protective cab (31) for the operator of a walk-behind tractor such as a snowthrower (11) is enclosed on its front and lateral sides by large window panels (51, 52, 53) of transparent plastic material extending between a top (32) and a bottom shroud (101). A pair of frames (56, 57) interconnect the top (32), the panels (51, 52, 53) and the shroud (101) and together with a pair of braces (121, 122) connect the cab to the handlebars (17, 18) and handlebar support (16). A transverse trough (34) minimizes flow of water over the rear edge of the roof (32) thus enhancing the comfort of the operator. The shroud (101) protects the operator against upwardly swirling winds and provides pocket means useful for temporarily storing personal items.
