The ditch bucket I was supplied with for my Cat 303.5 C cr is an aftermarket and I have a couple of issues. First...when I got it the dealer had to install a flow restrictor in one of the lines because as soon as you would try to angle it the thing would move at the speed of light! There was no way to control it....the flow restrictor has hepled. Second and more annoying is that as soon as the bucket contacts hard ground it will not hold the angle I have set it at....it is like digging with a rubber bucket LOL. What would be the likely problem?
