Okay....you know you don't have live hydraulics; I hope you're aware that you don't have double-acting hydraulics, either. Plumb the two cylinders to the front port on the left and the one on the right. If your cylinders have line to each end of them, remove the line that retracts the cylinders and install a "breather plug" in those cylinder ports. Oil under pressure will flow into the end of both cylinders when the hydraulic control rod is pulled all the way back. Releasing the rod to the little "step" on it will hold the loader in position. Pushing the lever all the way forward will release pressure on the cylinders. Gravity will lower the loader. You didn't say....but this setup isn't going to work if you have a hydraulic cylinder on the loader bucket. If you have a "trip" loader, you'll be fine. If the bucket is hydraulically controlled, you're going to need considerable extra plumbing to provide two-way hydraulic power.
