it should be 3 pieces for the blade, not counting the front
attaching support plates (they bolt to the front side frame
of the tractor)
there's a box type part that pins into the above mentioned
front support kit.
then the front hitch pins onto that,
and the blade goes on the hitch, all with
quick pull pins and no tools (except for the
front support kit)
hydraulic lines hook up where loader couplers are,
color coded (although a running change may leave you
with reb/blue on tractor and not the blade)
if everything is in boxes, that's another story,
you will have to assemble the hitch with the cylinders.
