Looking at the rotor, on a 8010 or 8120, are the rub bars sticking out from the rotor about 2 inches on the standard sized specialty rotor? How about on a small tube rotor? What are the measurement there? Thanks.

The OD or outside diameter with the rasp bars on is the same between the standard and the small tube. The small tube has a 3" smaller rotor tube that the standoffs are welded onto. Is that what you are asking about?

So if the small tube rotor is 3" smaller in diameter, than the rub bars and pedestals would stick out 3.5" from the skin of the rotor as opposed to 2" on the standard rotor?

When they say 30" rotor, do they mean from bar tip to tip or is that just the tube diameter? Guess I've never measured but I swear the rotors look like the tip to tip diameter is larger than what they say the size is.

I dont know for sure, so confirm anything I say with someone that does know. But I think the 30" is stand off diameter without rasp bars. I had to make a plywood cutout of the rotor several years back for some concave and grate work I doing at the time for grass and small seeds. It's been too many years, but I do recall the diameter with the rasp bars I had on at the time, was around 32". That was calculated using the circumference as I did not have a caliper that big.:) I guess I could have made one, but calculating diameter from the circumference was easy enough.

Perhaps someone with a definite answer will respond. I too am curious to know for sure.

Guess that would make sense, ours is a 24" rotor and the tube looks close to the size as the auger tube in the 1020 header we got and that is listed as 23.6" diameter.
