Friend has my old 8640 on a new JD 34' 2623 disk with finger and rolling harrows.
Deere says that you need 2900psi to lift the wings...maybe more.
Tractor is 'almost' there, but not quite.
Anybody have any ideas short of adding cylinders?
How high could you crank the pressure up on an old 40 series without causing issues?
