This is a very old idea.  I first saw it in Popular Electronics about
thirty mumble years ago.  I can think of other disadvantages:

     The yard must be clear of all obstacles (anything not accounted for
     in the wire's path and/or mower's ground clearance).

     The yard better be guaranteed clear of small children and pets.

     If the mower hits a bump and takes off at a sharp enough angle, it
     will lose the wire and get lost.

Remember, you're dealing with a massive blade driven by a gasoline powered
engine.  The potential for damage is serious. (Now you know why there
aren't any commercial versions on the market).
