Abstract
In the operation of work machines having an ejector blade pivotally coupled to a cylinder by cylinder-attached pivot pins, it has been a problem reducing the stress acting on the pivot pins caused by, for one example, improperly set yaw rollers. The present invention provides for an ejector arrangement for a work machine in which a coupler is pivotally coupled to the cylinder and pivotally coupled with the ejector blade.
