PURPOSE:To provide a load sensing structure for a working vehicle of such a constitution as determining the load applied on an engine from the difference between the sensing value of a revolving speed sensor when the engine is free from load determined previously and stored in a memory means and the sensing value of the revolving speed sensor of the engine at the present, wherein the sensing value of the revolving speed sensor when no load is applied stored in the memory means is corrected automatically from time to time. CONSTITUTION:Main clutches 5, 6 are installed between an engine 1 and a transmission A on the down side, and a revolving speed sensor 30 is furnished to sense the revolving speed of the engine 1, and when the main clutches 5, 6 are disengaged, the sensing value of the sensor 30 when no load is applied to the engine 1 corresponding to the accel. opening at this time is presumed on the basis of the change in the sensing value of the sensor 30, and the sensing value of the sensor 30 with no load corresponding to each accel. opening stored in the memory means is corrected automatically each time the sensing value of the sensor 30 with no load is determined. |
