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.

The proper drive establishing force is indicated by the relative position of the end (91) of a control link (36) and the end (92) of a spring coil (49) of a coil spring (47) by which resilient clutch engaging force is transmitted to a transmission clutching mechanism (65,66) by a hand lever (26).

Mechanism for indicating drive engaging force

A seal (41 or 141) is provided at the pivot joint between a deflector (19) and a snow chute (18) which has spaced fingers (42 or 142) permitting the leading edge of the seal (41 or 141) to conform to a reduced linear dimension when the deflector (19) is pivotal to a forward position of adjustment about its pivot axis (22).
