Hydraulic Cylinder Jerky

[confederatemule]

I had a cylinder on repaired on my ditch bank flail mower. In one direction it is very jerky. Is this air trapped in the system and will it work itself out?
The cylinder leaked when I extended it for the first time I tried to use it. Therefore I don't know if it jerked before I had it repaired. Due to circumstances beyond my control I did not put it on my tractor until the 2 year warranty had expired.
Thanks for any help.

Does this cylinder have a pilot operated check valve? Similar to that valve block on top of the cylinder in the picture below:

Anyway, cycle a couple of times to rule any possible air in the cylinder, but I wouldn't push the lever all the way. I would just feather the controls to not let gravity take over and create a "sloppy bucket syndrome".
