Near Intersection of I-35 & I-90 Southern Mn. | Some of the first things that come to mind are 1) are the cylinders in the correct locations? Often times the cylinders are plumbed in a master slave combination where the oil going out of the rod end on the first cylinder(s) leads to the base end of the next cylinder to keep them in phase. This requires that the next cylinder have a somewhat smaller bore. 2) are the hoses routed correctly.
Does your 255 have the fancy auto depth control? if so the situation is more complicated.
If the dealer messed up initially, I would think they would have an obligation to get this figured out for you. If it worked properly last year, it may have gotten some air in the system over Winter. Many systems have a method to bleed out accumulated air in a system. Some have a removable plug, others have a bypass port that opens a passageway if the hydraulic control is held in the extended or retracted position for a long time. Again the dealer should be aware of these methods.
Some years ago, a salesman brought out a new tillage tool to a neighbors field for a demo. It was brand new and had never been used prior to this demo. It wasn't level and they started adjusting the various turnbuckles in an attempt to get it to run level. I noticed that the cylinders were the rephasing type and two were placed in the opposite locations of where they should have been. I tried to explain this to the salesman but he wouldn't listen. The demo was a flop for several reasons.
