Hello. So I purchased a Ford 3000 pretty cheap and at the time of buying it the 3 point arms raised and lowered very slowly. So I decided to change the fluids. To my discovery it was mixed with water (aka Starbucks coffee). I flushed the system with 15 gallons of AG 20 hydraulic fluid. Arms would not raise. I drained the last of the AG20 and replaced with Tractor supply VP something. It said it meet the Ford 134d spec. I thought I was good because the arms raised but while driving it around I lowered the arms to cycle the system and they will not raise. Im stumped. Im reading the book now but I cant see the problem right now. Any advice would be nice thank you
