Question on D9E model

I just received the new D9E model and it is one of the nicest models I have ever seen. My question is where was the hydraulic tank located on the real tractor and also what was the purpose of the extended lower portion of the front grill.

I don't have much info on the 34A hydraulic controls so I'm going to guess...feel free to correct.

The basic hydraulic control for blade only is the #184 with hydraulic tank and control valve front mounted. (bump in grill). Used a single section separate hydraulic pump.

If you needed more valves, for tilt, ripper plus the blade the #193 hydraulic control with fender mount tank and separate two section hydraulic pump was utilized.

I believe the #191 (single valve for tilt) and the #192 (two valve tilt & ripper) on a cable blade could still be used.
