This is Henry's 1936 Briggs & Stratton 3 HP, belted to a squirrel cage blower. We call it our 'Olde Air Conditioner'. The blower itself is 12 inches wide and 12 inches diameter. With the engine running just above idle speed, it bends the grass down for about 5 feet. One tank of gas gives approximately 8 hours of operation at idle. Needless to say, this is a very popular exhibit at shows during July and August!
