PROBLEM TO BE SOLVED: To provide a rotation brush type paddy weeder capable of autonomously travelling, realizing various kinds of travel modes by two rotation brushes, reducing the number of components, and simplifying control.SOLUTION: In an automatic operation mode, following controls can be executed selectively: forward weeding travel control A driving right/left rotation brushes 3L, 3R in normal rotation； backward weeding travel control D driving the right/left rotation brushes 3L, 3R in reverse rotation； turn control C, F turning a direction of a machine body 2 to right/left by driving one right/left side of the rotation brushes 3L, 3R in normal rotation and driving the other side of the rotation brushes 3L, 3R in reverse rotation. In the turn control C, F, right/left turn directions are switched alternately in every execution.SELECTED DRAWING: Figure 1
