HYDRAULIC CLUTCH DEVICE OF AGRICULTURAL TRACTOR

摘要

PURPOSE:To facilitate assembling by making a supporting member and a center plate of a spool of a hydraulic control valve compatible and making the center plate to be used as an oil path plate. CONSTITUTION:A hydraulic control valve 80 is moved forward and backward by a shifter 80a in a mission case B. And the spool of the valve 80 is passed through a center plate E and the shifter 80a is taken out of the mission case B by a shaft to become an arm 79, and is operated by a PTO clutch lever of the outside. The compressed oil forwarding to a PTO clutch shaft 7 of PTO after controlled by the valve 80 is come out to an open oil path 82 on the front face of the center plate E. And the oil path is convered with an oil plate 88 and sealed. The oil path b is made an oil path for lubrication of the PTO clutch shaft, and a back chamber of a front housing and the case B holding the plate E between are communicated to become an integral oil bath.
