The exhaust gas amount of tractors on rotary tillage has been estimated by means of the reproduction method of the actual work on the report part 1 to observe the situation of the exhaust gas on actual field work. On this report, the relation between the exhaust gas amount and the condition on field work, such as PTO load and engine speed was investigated. To understand the relation, the amount of exhaust gas from the actual rotary tillage with various traveling speed and engine speed was estimated, and the changes of estimated C1 mode test results (which represents the amount of exhaust gas from general work of non-road engine) by varying PTO load and engine speed was also considered. As a result, it was made clear that every tractor has its own tendency of changing the amount of exhaust gas by varying PTO load and engine speed, and it seemed possible to decrease each exhaust gas component by considering the tendency and selecting the suitable PTO load and engine speed.
