Traded Kuhn Speed Rake for Kuhn 6501 double center rotary

I had a thread a week ago on switching rakes, just got it done.

 

Cost me some money, but what the heck.

 

From you double rotary guys, what does a newbie need to know? Anything specific on Kuhns or the center delivery?

 

I assume you let the rotors down and put it in float mode and let the bogies ride up and down? (After the height/width is set I assume as well) Did Kuhn fix the float issue on rotaries like they did on the Gen II speed rakes, so you don't have to worry about forgetting float mode on the tractor?

 

What RPM and speed does one nestle into on a alfalfa or alfalfa/orchard crop?
