Haven't been here in a long time. Had to re-register. I replaced a 5 inch piece of hydraulic hose that connects two lines under the hood  because it was leaking. This is a 2007 tractor. Now the lift arms are extremely slow to lower. I'm assuming air got into in the hydraulic system when I removed the old piece of hose.  Is that the problem. How to fix it?  Thanks for any help.
