Claims

[Scope of utility model registration request]

A tail wheel support that supports the tail wheel is connected to the 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. Rotate the lock body until it passes a position beyond the fulcrum point where the biasing force of the spring acts in a direction to rotate the lock body toward the lock position when the swing arm swings in the direction in which the ring rises. A tail wheel floating device for a rotary tiller, characterized in that a biasing body for moving the swing arm is provided on the swing arm.
