<p><P>PROBLEM TO BE SOLVED: To provide a travel vehicle for irregular ground capable of escaping from a stuck state without excessive throttle operation when a vehicle falls into the stuck state and of preventing premature wear of a V-belt or the like. <P>SOLUTION: This vehicle is provided with an engine rotation speed detection device 30, a power downstream side rotation speed detection device 31 detecting rotation speed of a rotary member arranged in a power downstream side of a power intermitting part of a clutch device such as a main propeller shaft 20, and an engine rotation speed change means such as an ignition device 34. The ignition device 34 is controlled to keep engine rotation speed N not to exceed predetermined limit rotation speed value in a range from an engagement rotation speed to predetermined maximum limit rotation speed when rotation speed of the main propeller shaft 20 detected by the power downstream side rotation speed detection device 31 is lower than a set rotation speed value predetermined in a range from zero to rotation speed at a time of engagement rotation speed of the engine 3. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
