Abstract
PURPOSE:To prevent a reaping device from thrusting into soil, by controlling drop of a reaping device in a fixed time after OFF state of an earth sensor and not carrying out dropping control by the earth sensor when dropping is detected by a reaping height sensor in the fixed time. CONSTITUTION:A reaping device is raised, an earth sensor 3 is made into an OFF state and the reaping device is subjected to dropping control in a fixed time. In the fixed time, reaping height is measured by a reaping height sensor 4. Since dropping control by the earth sensor 3 is not carried out when dropping is detected by the measured result by the reaping height sensor, a pulse signal is outputted detection to a solenoid of a dropping valve 15 by the dropping detection to drop the reaping device. Reaping height control is carried out by the reaping height sensor 4 and reaping operation is done. Consequently, the reaping device will not thrust into soil by excessive dropping and stable reaping operation can be carried out.
