Elderly relative passed last yr, his nephew is getting rid of ol,junk tools equip, family has first chance, other than few select tools, wall hangers etc, got a wd parts tractor for my wd45, it intrigued me because of bent shifter, was thinking late wd, serial wd221549' which makes it a wd45, yet engine has side plate, like a wd, trans has bent shifter, late wd or 45, any other features or differences that I can use to determine whether it was a wd with latter wd 45 trans and rear end or a wd 45 with a wd motor,?? Dunno what I'm getting but it's free to me and I know I can use some parts thanks
