This is the 5" channel and the pieces of 3" channel that the cutting edge(from snowplow) will bolt to.
This is a closer view with the cutting edge in place.
What you can't see is the braces that are on the 'inside' of the 5" channel.
They are to reinforce the lower flange of the 5" channel so the cutting edge can't fold it back in use.
This shows the brackets that the long 5" sq. tube will bolt onto.
This shows the jack that is used to adjust the hieght of the cutting edge.
