: : : : : If I pull the handle to make the loader go up it goes slowly. If I pull the lever about 1/2 way, it goes as fast as you woul expect. Also, if you put the bucket all the way up, it will come down on its own fast enough to see it then it slows down, then it will drop fast again. It seem to have certain spots were it willcome down, maybe a foot in a couple minutes. Can be handy for setting poles by yourself, but hell if your trying to work out the bucket. : : : : The more I think about it, it sounds like the piston seals have blown out of the lift cylinders, if they are two way. The lifting that you are doing is by displacing the rods out of the cylinders. One way to check this out is to raise the bucket off the ground about a foot or so and unscrew one of the hoses at the end of the cylinder that the rod comes out of. If the loader trys to settles the rest of the way down, you will need to have the piston packing replaced. : : : :::Very interesting, could you explain in more detail, how you lift "by displacing the rods out of the cylinder".

: : I'm not sure I understand your question. The pistons have a hydrolic line at the top and the bottom of the piston. I thougt this would make them two way pistons, but they don't power down. A snow plow piston just has a line at the top to power up, and when you release the valve the weight brings it down? I don't know much about hydrolics, but this is how I thought it worked. When I saw a line at the top and bottom of the piston whith no power down, it once again showed me just how little i know. : If your piston seals are leaking or bypassing, you won't have much down pressure if any. The lift cylinders will have more power lifting than they will pulling down because there is less piston surface due to the rod being in the center of it.
