Yup !!! Lifting my mill even with the table and motor off really tore me up but I had no alternative. I'm a 63 years old fart. (Also my mill is a bit lighter than yours).
The trick set-up for waltzing these things around is to use a portable engine hoist (rented, borrowed, etc...)' My nephew and I moved his beefy Cincinatti bench mill (ex- US Army Ordnance shop machine) using his portable engine hoist. We horsed it accross his backyard and into his small shed-shop in two sections. Both sections were way too heavy for us to lift manually.
