Re: 780 selectamatic loader spool challenge...

success!

Re: 780 selectamatic loader spool challenge...

Thanks chaps , Ollek,Ok thank you so that would explain why the boom lifts when the lever is up (and drops with gravity when the lever is up a little, and does nothing but make the pump noise when down) but the bucket is connected to a double acting valve and fights itself, with both lift and lower....
