Quick Attach Angle

[Silver_Knight]

I have a JD 3720 with a Quick Attach on the 3 point. I also have TNT and my question is how far should I be able to tilt the rear blade or rake? It seems that I cannot tilt it far enough but there is no adjustment since there is a hydraulic cylinder. Is it possible the dealer installed a TNT with a cylinder that is too short or is this normal.

I have a grademaster and cannot get it flat on the surface without adding a plate and moving the top pin towards the tractor about 2 inches.

Any suggestions?
