That all depends. My set up is ideal for me. All the way in has the cutting edge about 1.5" off the surface allowing me to easily spread gravel/dirt. The front or leading edges are all that touch on firm surfaces. Extend my hydraulic link about 2 to 3 inches and my cutting edge is now at the proper cutting angle. Fully extend my top link and I am in final pass grading mode as the front cutting edge is completely off the ground and only the back of the rear blade is touching. When my surface to cut is covered in heavy sod, I tilt or extend my link just enough to get the rear cutting edge into the surface and drive backwards peeling the sod away, something that works well on my Kubota(s) and bends the daylights out of our NH 2120 lower links. Experimentation is the only way your going to get it. A hydraulic top link is the ideal way. I use mine not only for immediate angle adjustment, but also while spreading material while moving. With a boxblade full of material, be it gravel or dirt, I can easily spread a thin layer elsewhere simply by going from a cutting configuration, 2" or 3" of top link out to spread configuration, top link fully retracted all while moving, something a manual top link simply cannot do.
