The saw---90hp 500cc water cooled HUSQVARNA motorcycle engine. running a 36" custom made guide bar and special hand made 1/2 pitch square ground chain. The saw runs a 16 tooth drive sprocket that is also custom built. Everything about this saw is custom made for speed. Gary and his partner Steve Ingalls designed and built THE IRON HOURSE as it's called. However, the compitition has a lot of different names they call it. *@##@$%% and so on. None of them were very nice. But sticks and stones------ If you counted all the time involved in the design and CAD time on the computer, plus building special parts the cost would be in excess of $35,000.00. The saw has never been beaten at a logging show. Gary holds the worlds speed cutting record through a 27" log of 2.34sec set at Morton, Washington's Grand finals.
