PROBLEM TO BE SOLVED: To solve the problems that lubricating oil results to be localized solely in a part of a reaping blade device and can not be uniformly spread out over the whole of the reaping blade device caused by the constant discharge pressure of the lubricating oil discharged from an oiling nozzle when an oil lubrication pump is once driven, while in a part where the lubricating oil localizes, excess lubricating oil results to drip down under the reaping blade device caused by prolonged time of oil lubrication.SOLUTION: The reaping blade device (32) is constituted to be uniformly oiled throughout the device by installing a controlling unit (61) for controlling an oil lubrication device (40) to automatically and forcedly control the discharge pressure of the lubricating oil discharged from the oiling nozzle (49). |
