Park the Roper tractor on a level surface. Cement works best.
Place the snowplow attachment right-side up in front of the tractor on the ground.
Lay out all of the spacers, nuts and bolts that came with your attachment.
Lift the snowplow attachment up to the front of the tractor. Slide enough spacers between the attachment and the tractor so that the attachment fits against the tractor tightly.
Push the bolts through the attachment, spacers and tractor frame and then attach the nuts to the bolts. Use a wrench to tighten them.
