Title:
WORKING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2004/056603
Kind Code:
A1
Abstract:
A working vehicle is provided with a speed changer (48) that is driven by the output of an engine (2) and changes the working speed. A working speed change operation member (30) for operating the speed of the speed changer (48) and an engine revolution change member (87) for changing the rotational speed of the engine are interlocked through a connection member (88). In a working vehicle, such as a rice planter where a speed changer for changing the working speed such as the traveling speed is driven by the engine output, the rotational speed of the engine is always set to a low value when the vehicle is, for example, in a low work speed state as in traveling or in a stationary state. This results that the engine is operated quietly and effectively for excellent work performance.
