伝達が不安定になるという問題点があった。
In the conventional apparatus, since the input sprocket of the reverse transmission mechanism is provided on the inner side of the chain of the chain of the chain transmission mechanism, the angle at which the chain is wound around the sprocket cannot be increased. Therefore, when the chain pulsates due to the impact load caused by driving the tilling rotary into the soil, there is a problem that tooth jumping of the chain occurs and transmission of driving force to the sprocket becomes unstable.
