That blade has all the nice hydraulic options, hydraulic offset to get off to the side of your tractor, hydraulic tilt ideal for crowning as well as ditching.
Combine the hydraulic offset with the hydraulic tilt and angle you can dig a good ditch and roll the dirt right up were you want it, then come back and feather out the dirt without leaving your seat. The hydraulic angle allows you to decide on the go which side your dirt and or stones will spill off of.
The hydraulic tail wheel would be handy for grading and reducing washboards.
Top and tilt are very limited in what they can accomplish the tilt can angle the blade a bit but not as well as tilt on the blade.
The top is only going to change your blade edge attack angle.
With the addition of diverter valves one set of remotes can perform many functions.
