I have a 771 loader on a 1900 tractor, the question is when I tilt the bucket back all the way it is not tilted much more than a few degrees above level? The cyl that tilt the bucket back are pulled all the way in. It will tilt down all the way. Is this the way they all work or maybe I have the wrong bucket on it, not sure since I purchased the tractor and loader used. thanks for any information. Joe
