Hobart N50

I'm a very new bread baker so I apologize for the naivete of my query.

I have a Hobart N50 (5quart bowl capacity) but need the dough hook.  I imagine that this will be able to handle heavy dough.  However, upon looking at the product specification, there is no dough weight/volume capacity listed for some of the heavier breads;  instead there are dashes (---).  Does this mean this mixer is unable to handle heavier breads?
