Hello--I'm new to the forum and I have recently bought a 1979 B7100DT which came with a B205 dozer blade made for Kubota by ARPS. I have no idea how or if this blade will mount on the tractor. There is the frame for it on the tractor, but I question whether or not this thing is going to damage the front diff. housing--or is the B205 not meant to be used with the 4wd model? This blade is a formidable hunk of metal--it took three of us to move it! Thanks for any help or advise you can think of.
