The working efficiency of a tractor decreases when operated on a field where there are obstacles. In this study, a telephone wire pole was used as an obstacle.When a tractor approaches an obstacle, the operator has to change its direction of motion to avoid it. As a result, some of the field area around the obstacle is inaccessible by machinery. Therefore, a labor force is required as in the case of traditional methods where a farmer works manually for cultivation and harvesting.In order to utilize the remaining area of land around the obstacle, a tractor maneuvering method is essential.To solve these problems, a one seventh scale model of the tractor (Mitsubishi R-4300) was designed and constructed. The motion path of the turning curve was measured at the test field, and both the Mitsubishi R-4300 type tractor and the model tractor showed an improved locus. It has been used continuously for simulation testing to realize the benefit of rational planning for the motion path of the tractor around obstacles.
