Mike, find out the model number. I just looked up a Hobart d300 (30 qt) and d340 (40 qt). According to the seller’s site, the 30 qt is 115v single phase with a 3/4 hp motor. The d340 shows to be 208v three phase with a 1.5hp motor. I know in the 60 quart line, Hobart has as little as 1.5hp (maybe even 1hp) up to at least 2hp and higher I believe. Hobart is a good company to call for customer service. They’ve helped me out with questions on used mixers before.
