I love making bread, but my Kitchenaid Pro 600 may be fine for whipping cream or making cakes and frosting, but it is NOT for kneading dough. Following all Kitchenaid recommendations, it can rarely get through enough dough for two loaves without overheating and shutting down. But I think I've solved the problem. This bad-boy is 15.5" x 15.5" x 24" and weighs in at 88lbs. It has a 1hp motor. It should be here in about ten days. I can't wait!
