Document Type and Number:
WIPO Patent Application WO/2019/198707
Kind Code:
A1
Abstract:
The present invention is equipped with: a reaping unit that reaps the culm of planted cereals in a field and is supported on a harvester body such that the reaping unit can be raised and lowered in the vertical direction; an actuator 11 that operates to raise and lower the reaping unit; a cutting height sensor 36 that detects the actual height H from the ground of the reaping unit; a cutting height control unit 52 that, on the basis of the actual height H from the ground and a preset target height HT from the ground for the reaping unit, executes drive control for controlling driving of the actuator 11 such that the height of the reaping unit from to the ground approaches the target height HT from the ground; a pattern determination unit 51 that determines a control pattern for the drive control and outputs the control pattern to the cutting height control unit 52; and a manipulation tool 56 that, by means of human manipulation, can command the driving sensitivity of the actuator 11. The pattern determination unit 51 changes the control pattern on the basis of a command value from the manipulation tool 56, and the cutting height control unit 52 executes drive control on the basis of the control pattern.
