So.... my front end loader on my bx2670 is wonky. When I first start to raise bucket, it falls instead of raising. Only when I pull all the way back does it start to go up... and really only if RPMs are high. Otherwise, it just falls. If I release to the neutral position, it will stop falling. But if I slightly start to raise it, it resumes falling. I don't think its the cylinders because bucket doesn't fall when left overnight. Sounds like a control valve issue and apparently, they cost a fortune! Any ideas. I apologize in advance if my question displays my ignorance!
