Laura Paynter posted a serious fire in one of these on the ytmag Tractor Talk Forum on 9-26-08, asking about fires in these; others replied that yes, they had had fires. It seems these, or some of these, have a fan that picks up chaff etc from the ground and blows it into the engine compartment or past the engine?? If you've had a fire in one of these, or know of any, Laura would like to hear from you; she can be reached thru the ytmag site.
