    When trying to back blade using down pressure, my 1840 (4000 hrs) lift cylinders will occasionally "bounce", as in retract and then spring back. It also acts up when I tilt forward and apply down pressure with the tilt cylinders as well. If I don't apply down pressure with the lift cylinders...
