Kubota B2400 hydraulic issue

[2006LJRubicon]

I have a B2400 with a trencher and a front blade attached. I recently had a leak in a line. I replaced the line and now I can not get the trencher to raise up. It is acting like it is trying to lift but is unable. I have started the engine, left it at idle, cracked open the line to make sure there wasn't any air in the line. I also checked other lines the same way. They all seem to be free of air. I have verified that I have plenty of fluid. What would be te next step to check with my issue? Any and all help will be greatly appreciated
