Claims

[Scope of Claim for Utility Model Registration] A transmission case that receives power from the prime mover connects and disconnects power transmission from the transmission case to the rear wheels on a vehicle body frame that is equipped with a prime mover and is equipped with front wheels, rear wheels, and a steering handle. In a walk-behind automatic deep cultivator equipped with a traveling clutch mechanism that moves up and down, and a tilling hoe that moves up and down via a crank mechanism that receives power from a transmission case, the power transmission from the transmission case to the crank mechanism is connected and disconnected. At the same time, a tilling hoe operating mechanism is provided that stops the crank movement of the tilling hoe at top dead center when power transmission to the crank mechanism is cut off, and operating levers are provided on the left and right grips of the steering handle, and the operation A plowing hoe operating mechanism is connected to one of the levers,
A tillage hoe top dead center stop device for an automatic deep tillage machine, characterized in that the traveling clutch mechanism is connected to the other of the operating levers.
