Claims

[Scope of utility model registration request]

A tail wheel support that supports a tail wheel is connected to a rotary body so as to be freely rotatable in the vertical direction, and a swing arm that is swingably connected to the rotary body is connected to the tail wheel support through a plowing depth adjustment rod. and a locking body that is rotatable at a locking position where the swinging arm is locked so that the swinging arm cannot swing when the tail wheel support is lowered and a locking position where the swinging arm is released from the locked state. In the tail wheel floating device of the rotary tilling device, a spring is provided which biases the lock body toward the lock position and the lock release position direction by an action across a fulcrum according to the rotation position of the lock body, and the tail wheel floats. The swinging arm is provided with a biasing body that rotates the lock body toward the lock position when the swing arm swings in a direction in which the ring rises, and when the lock body is rotated by the biasing body. A rotational position adjusting body for adjusting the rotational position of the lock body between a position where the direction of action of the biasing force of the spring does not go beyond the fulcrum and a position where the direction of action of the biasing force of the spring does not go beyond the fulcrum is placed opposite to the biasing body, and A tail wheel floating device for a rotary tiller, characterized in that it is movably attached to a rotary tiller.
