My dad mowed raked and baled in the 1960's with a Ford 600. Although sometimes he baled with the Farmall H. They were great times although I didn't think so at the time.
We had a 640 and a harrow much like that. We had to get over the field so it was third gear or the planting would be late. You did well to get it bite into that dry ground.
That old Ford tractor has come a long way from your part 1 video on it. Maybe you're get lucky and find a better hood and doglegs for it. Dennis Carpenters has new reproduction ones, but at a very, very high price. Do you have a plow for it? Cat 1, 3 point two bottom plows can be had used for a pretty good price if you don't have one.
