Abstract
PURPOSE:To prevent a reaping device from thrusting into soil and to avoid high reaping, by controlling an intermittent rise output time of a sensor in a fixed timed irrespective of long or short grounding detection time of the earth sensor. CONSTITUTION:When the tip part of a reaping device is ground during reaping operation, the grounding is detected by an earth sensor 3 and the earth sensor is made into an ON state. A pulse signal having a fixed ON time is started from a pulse generating circuit 20 by ON of the earth sensor 3 only once and inputted to a solenoid of a rise valve 14 to raise a reaping device. Even if the reaping device is raised by the one pulse signal and the earth sensor 3 is not made into an OFF state, rise output is stopped when an ON time of the pulse signal elapses. In this manner, reaping operation is carried out while smoothly controlling the reaping device along soil face not to make the tip of the reaping device thrust into soil.
