I have a 1954 john deere 60. I recently got a barge box wagon with a 7 ton Midwest hoist with 1 hydraulic hose. I couldn't get the box to go up even when empty. I did a little research and added another hose to the ram end of the cylinder. It still won't go up. I added a little fluid to the powertrol reservoir and it still won't go up. Should I have filled the new hose before installing? Is the hoist cylinder bad? My tractor will run a two hose cylinder on my 3x14 plow and our harrowgator so I know my pump is working right. Not much experience with box lift cylinders. Any advice helps. Thanks in advance.
