To study the possibility of rising work efficiency by introducing farm-road-turning form (use farm road for turning = F. R. T.), the simulation according to the working strokes of F. R. T. and standard-turning form (turning in the field = S. T.) was done at rice transplanting work. The results are as follows; 1) When the return work turning time (t1) is shorter than 3 times of the head land work turning time (t2) at the S. T, the turning time at the F. R. T. (t1') must be shorter than ((a - 1)/(a + 1)) t1 + (2/(a + 1)) 3t2. And t1' must be closer to the t1 according as the short side length of the field becomes long. To make shortning the total turning time, the design of the farm land consolidation which were connected with climbing capacity of rice transplanter, the turning form and so on must be considered. 2) The transplanter which has wide operating width is useful for the F. R. T. 3) The work is started at the time when the transplanter is got in the field, and it is stopped when it is gone out the field. The transplanter can be gone out from anywhere of the short side of the field. So, moving time of the F. R. T. will be shorter than the S. T. 4) The support workers can supply the materials with little restrictions at the F. R. T. As the final return works turning involves head land works at the S. T, the required distance might be longer than the regular workable distance. And it will cause an another materials supply. So, supply time of the F. R. T. will have a possibility to be shorter than the S. T
