The clutches hold the mount axes tight to the rotating parts driven by the motors. In the iexos these are the silver knobs one at the back of the mount head along the ra axis and one at the top of the weight bar. When these are tight the mount won’t move except for the motors moving them. When you loosen them you can swing the mint around by hand.
