PURPOSE:To secure safety by installing a traveling reset means which prohibits restart, unless an operating lever is once returned to a neutral position, when a brake is once operated. CONSTITUTION:If right and left brake pedals 16a and 16b are stepped once during traveling, a brake switch 15 is turned-ON, and a clutch-off means 5a built in a control part 5 operates, and a hydraulic clutch 11 is turned OFF, and the traveling of a machine body 20 is braked by a brake mechanism, and the power transmission from an engine 12 to an axle is cut off. Further, if the hydraulic clutch 11 is cut OFF by the clutch off means 5a, a traveling reset means 5b operates, and if an operating lever 1 is not once returned to a neutral position N, stepping a brake pedal 16, the hydraulic clutch 11 is not turned ON, even if a foot is separated from a brake pedal 10. Accordingly, after brake is applied sharply in order to avoid the hindrance by persons, articles, etc., traveling is prevented even if brake application is suspended. |
