Hello looking for advice, I'm a new ford owner been around them most of my life as my father has one but I have not done any work on them... Was using a cherry picker and moving some cedar logs around. While doing this at one point hydraulics seemed to start pulsing or chattering. Adjusted lever and it went away..continued to use for a few more logs than I parked it. Next time I pulled out of garage I have no hydraulics move lever up and down and nothing no noise from pump. I can grab lift arms and move up and down with hardly any resistance....not sure what's going on, seal on cylinder under the seat or something u should check. Any and all advice welcome!!
