Southeast Florida | I’m fairly savvy with hydraulics but I’ll be damned if I can figure out how JD can put PFC a valve body on a tractor that has nothing but gear pumps on it. I was thumbing threw the literature on them 5625’s and saw where they offer PFC on the triple deluxe valve bank. I understand perfectly how PFC works on piston pumps with the signal line but a gear pump is beyond my comprehension of how it works without heating the oil threw a pressure relief valve. | |
