From surveys of R. M. R. of farm workers using farm machines on paddy fields, the following results were obtained;
(1) R. M. R. of using tractors were 1.0-1.8, which were cousidered to have relation with the seating arrangement, controls of tractor, and working speeds.
(2) R. M. R. of using power tillers were 2.6-5.2 for tilling, and 1.9-3.8 for puddling.
(3) R. M. R. of using rice transplanters (by human power) were 3.4-4.6, of using cultivating implements 5.1-5.2 and of using binders 2.2-2.6.
(4) Generally, it was considered that the value of R. M. R. when using farm machinery had to do with working speeds and the condition of field surfaces.
(5) R. M. R. of caring the machinery were 2.8-3.1, and of changing wheels or tillage blades were 1.7-1.9.
