my hydro fluid is full. i have tried bleading the line to make sure there is no air in it. But i took and had my younger brother pull the lever to dump it, why i was pulling down on the bucket. it was tuff but finally it gave and broke past a point that it started workin on its own. but when it gets half way back up it will not dump unless i pull on it. I also dis-connected both cylinders from the bucket, to see if they both would extend. ( while in the seat ) the cylinder on the right would only extend 8 or 9 inches. the one on the left wouldnt even budge.
