probably breathing in all the exhaust fumes but with all that noise and vibration it should be banging...try some lime and don't bag it mulch it....just shut the vent door on the mower and go..if you have wheel height settings set it in the middle 12oclock positionIMPORTANT in the real hot weather raise it up one click to shade the roots so it doesn't shut itself down and go brown...water at night/dusk not during the days heat the nutriants from your lawn are in the clippings.don't fertilize it it will shock it into oblivion...water mulch and lime it
bag of seed might help general type is cool
