Strange you should mention a Cub trencher, John. I saw one last month at the tractor parade I went to. The construction yellow paint was somewhat faded on the tractor. I guess we could say it was in it's work clothes. The one I saw had a dirt blade on the front, rather than a bucket. The back unit looked similar to a ditch witch. I am remembering probably four or five feet long on the ditcher. Sadly, I just walked past the machine without paying much attention. I only noticed it because it was an unusual item. I looked through my pictures and I only caught bits and pieces of the machine in about three shots. It is safe to conclude that there are at least two of them.
