Faunsdale, AL | Are you having to add fluid?
Have you checked for leaks on the steel line across the back of the header? Seems like you would have a mess somewhere making the leak obvious.
But I agree, if the control valve was leaking, if the circuit has been properly bled, the whole reel should lower evenly.
I had a hard time getting the trapped air out of the circuit on my 930F. Seems like the left cylinder should bypass oil when fully extended but mine didn’t or it was so insignificant that it wouldn’t purge the line. Maybe they’re all that way?
Is it possible that your master cylinder (Left side) will leak when it’s extended just the normal amount but not fully? If the seal on the piston of the master is bypassing oil, the reel would settle on that side but it seems like you would soon get out of sync and have to bleed the slave to get the reel back level.
Could you swap the reel raise for one of the reel fore and aft hoses as a trial? I don’t know if all combines have the fore and aft circuit installed.
