New Holland TN60a Hydraulic issue

[Klbmotorsports]

I replaced my fuel leveler and my seat yesterday and now my hydraulics aren’t working. We filled the hydraulic fluid. It took the whole 5 gallon bucket. We see no leaks

I think you need to do a better job on your explanation. You had the seat off, and possibly part of the tinware below that to access the fuel tank? None of which SHOULD impact the hydraulic system in any way. What part of the hydraulics are you having problems with? What works and what doesn't?
