I have a 5 qt Hobart (N50). It uses all the kitchen aid attachments but it is more heavy duty. I got a used one about 40 yrs ago to go with the wheat grinder my husband made. I needed extra duty to make/knead wheat bread without taxing the motor. It is so important in our kitchen that Dad got both daughters a new one for their wedding gift. My youngest had hers whirling mashed potatoes when we arrived for thanksgiving dinner. My old one is still chugging and DH painted it so I would not be jealous of my girls. He painted it to match his tractor.
