Thanks Jeff.
I know it's a simple matter of pulling the hose off. I had the clamp off a month or so ago and was going to do just that, but the way my luck goes, I usually break something while trying to fix something else.
I'll give it another shot next spring, when the snow is gone and the grass is not ready to cut yet. That way I know that I'll have a month or so to get the tractor back into operation if I screw something up!
