Then why doesn't the other guy scream?     Only good thing is that the nitwit at least didn't yell over his co-announcer...at least not very often.  I found myself hoping the other guy  would talk during a run so that I could actually hear the tractor.

The run lasts all of about 10 seconds.  Surely he could manage to keep his mouth shut for that long, if he tried even a little bit.
