Super A hydraulics jumpy going up?

I changed the hydraulic fluid in my Super A a couple of months ago, and ever since changing it they lower nice and smooth, but are really 'jumpy' going up. Does that sound like air in the lines to you folks? How do you recommend dealing with whatever the problem is?

Thanks,
Darren

Over the years I have encountered much the same problem as you are having a few times. I has always happened right after draining or having lines off between pump and touch control. My experience is it usually goes away in a few days. When I think about it, I would have been working those tractors hard and long days those days. How much have you been using your tractor lately? I used to think when I was farming how great it would be to keep one of these little tractor around for playing and yard work. I'm finding they are more trouble than when they were worked all day.

Hugh, What you say makes good sense to me. It hasn't seen much use at all since the fluid change, and I didn't check the screen or bleed it through the line plugs (like I probably should have.) I'll get in there and check those things. I've heard a lot of folks on these forums say they had a huge improvement just cleaning the screen when their hydraulics went weak.

Thanks again for all your help. (this is about the 37th question you've answered for me!)
