Abstract
PURPOSE:To prevent excess rise of a reaping device at low speed and rise deficiency at high speed and to contrive to smoothly control the reaping device, by controlling rise output time short or long depending upon high or low traveling speed when grounding of the reaping device is detected. CONSTITUTION:When a weed separating lever of a reaping device is grounded, an earth sensor 3 is grounded, a switch is made into an ON state and an ON signal is inputted to a control device 19. When a traveling speed is higher than a given traveling speed depending upon high or low traveling speed at the operation, a pulse signal having long intermittent rise output time is started from a pulse generating pulse 20, outputted to a solenoid of a rise valve 14 and a hydraulic oil is fed to a rise and fall cylinder to control rise of the reaping device. If a traveling speed is lower than the given traveling speed when the earth sensor 3 is made into an ON state, a pulse signal having a short rise output time is started from the pulse generating circuit 20, outputted to the solenoid of the rise valve 14 and the reaping device is controlled to rise. When the reaping device is raised, the earth sensor 3 is made into an OFF state, the hydraulic oil is discharged from a rise and fall cylinder and the reaping device is dropped.
