There are similar cutters that mount on small tractors, that's how

Understood. They clear the roads out here all the time with a five foot
wide cutter than arcs high and can get behind the guardrails (banging
them up in the process).

That WOULD work for the part that I just cleared, but not for the part
deep down in the ravine 100 feet below (which is inaccessible to tractors
AFAIK).

Probably not in my budget though.
