Love Tractor Inc. Lift Disc Harrow

Just trying to find out as much info as possible about this 1940's vintage Love Disc Harrow. Starting with the Hitch set-up, is it possible to make this work with a 3-Point Hitch? Unfortunately this photo was taken into the sun, but you can see high point on the hitch, and then also a drop down double bar which seem to connect the left and right floating harrow bars. So there doesn't appear to be a way to attach to the two points of a 3-pt. set-up. Would also like to know about the care and feeding of the wooden greased bearings I read these have.
