I grew up on my Grandpa's Dairy Farm. He had a Model BG just like that. I used to pull a big old 14' Killifer with 20 inch disks. My great uncle used in to do the orchard work. My dad plowed with it using a three-bottom International trip plow with 14" moldboards and shares. The tractor, according to manual, was powered by a 35 hp six-cylinder engine. It was just an amazing machine!
