In order to grasp the effect which the operating speed, operating width and the coefficient of field lot form (long side/short side of field lot) exerts on the effective field efficiency, the effective field capacity is calculated by a simulation model. And the relation between field lot scale and the effective field efficiency is analyzed when different farm machinery and farm work machinery are used.The results are as follows:1) As the field lot scale increases the effective field efficiency increased at the rice cropping work (tilling-harrowing, puddling, rice transplanting and harvesting) and at the soybean cropping work (tilling-harrowing, planting, intertilling-weeding and harvesting). But the work accompanied by loading (seedling, fertilizer and seed) and unloading (unhulld rice) did not show much increase in the effective field efficiency. That shows there is little usefulness brought by increase of field lot in size. And the effective field efficiency of harvesting of soybean cropping showed a tendency similar to that of the tillingharrowing and others because the unloading time was excluded.2) The effective field efficiency decreased with the increase in operating speed. The discrepancy of effective field efficiency caused by the difference in operating speed was ramarkable in the work related to the loading and unloading.3) The effective field efficiency decreased with the increase in operating width. The discrepancy of effective field efficiency caused by the difference in operating width was remarkable in the work related to the loading and unloading. But if t1 (turning time of reciprocating work) is much larger than t2 (turning time of head land work), the effective field efficiency in the wide operating width is higher than that in the narrow one.4) The effective field efficiency in creased with the increase in the coefficient of field lot form. And such phenomena were remarkably found on smaller field lot scale.
