Re: "The router went dark"
We call them diggers. Or after the UK market leader JCB.
They did the first dedicated tractor style one or as well call them JCB.
From Wiki
In the same year, JCB launched the first European hydraulic loader, followed by a backhoe with a 180° slew, fitted to a tractor, in 1953. In 1957, CASE developed the first integrated tractor backhoe loader at the Case New Holland plant in Burlington, Vermont, helping contractors complete their work more efficiently.[8] JCB introduced the first dedicated backhoe loader, incorporating the excavator and the major loader in a single, all-purpose tool. [9]
Because of the long-time predominance of the JCB marque in the United Kingdom and Ireland, it has become a genericized trademark there, and backhoe-equipped diggers are commonly called JCBs, while the term "backhoe" as an excavator component is almost unknown to the general public in this context. The founder of the JCB company, Joseph Cyril Bamford, is the only Briton to be honored in the Association of Equipment Manufacturers Hall of Fame.[11]
There is a book about them.
