Hello, I know this has been discussed because it's a common problem but I can't seem to find any answers. I have a 1010 2wd series 2961. 3 point was working and stopped from what previous owner said so I changed the fluid and filter 2 times because it was milky. It will raise up with no weight but if I push down on it, it won't raise. I've tried turning the stay and float knob and no luck. Any help would be greatly appreciated
