Ive noticed when i reattach my loader on my bx 2370 when i curl the bucket down to get it to rock the loader arms into the cradles on the tractor if i stop half way to readjust something and then go back to curling down it starts curling up moving the loader arms away from the tractor i thought it was me pushing the lever the wrong direction at first but no either way i pushed the lever left or right it would only curl the bucket up until the bucket it flat on the ground and then it will start curling back down again when im doing this engine rpm is about 18 or 1900 does anybody elses do this or is oil leaking past a valve or something i hope i explained that ok
