The Ditchwitch guy said everyone uses "Ground Hog" trenchers;
these being a 5HP 3" wide 12-18" deep human-propelled unit. And
the Home Depot rents same for $340 a week.
It will make far more of a mess than a vibraplow but outside of
buying/building one...
There's one other manufacturer I just found;
http://eztrench.com/ -- that's a circular saw & narrower, but
finding one to rent will be the same adventure.
