In size and weight, they seem to be very close.
Here are two links that you can use for a bit of comparison.

Don't worry about the fact that the Bolens listed is a 1050 vs a 1220. There was very little difference in the Bolens tube frame tractors other than engine/horse power, so a lot of parts are interchangeable from tractor to tractor. Also, almost ALL of the tube frame attachments will fit any other tube frame. That makes finding attachments a lot easier.
I don't know about the CCs, but the 1220 has a 3 Sp trans with hi/lo range, and a controlled differential that when 'locked', gives you all of the traction you can use.
