Maybe it's a termonaligy thing.  How about cruse control then.  You used to
be able to get an after market cruse where you would glue a magnet to your
drive shaft and mount a pick up near by. There were electronics that mounted
in the cab and a servo that went on the throttle. The operator could get the
engine up to the speed he wanted and hit the cruse button, after that when
the load would bogg it down the cruse would kick in and goose the engine.

Another option would be a two position foot switch like on a spot welder
where position one closes the contacts and position two hits the current.
On the hammer the first position could throttle up the engine and position
two could engage the hammer.

Those kind of truck governors work the wrong way for what is needed. They
limit the max RPM.
What he needs is one that limits the minimum RPM
