I'm sure there are a ton of threads on similar issues, but I couldn't find my specific problem. I'll preface this by saying that this is my first tractor and I'm trying to figure things out as I go. The previous owner only used it for hay and never used the 3point. I plan on using it for the same, but would like to make sure everything works. So here's my issue. Through the valve it does nothing. When I try to raise it, I can hear the pump whine as it would when it's moving fluid, but no movement. When I move the load control lever down to L then the rockshaft go up to the top all by itself. If I try to lower them, nothing. I have to move them back to LD or D to get them to drop. Any help would be Appreciated
