The aircraft is a converted Boeing Stearman PT-13 (or one of the upgrade derivatives). The front cockpit has been replaced with a materials hopper (dry or wet). The engine appears to be the stock 220 HP Continental engine. I was a flagman and mixman during the 1960's for a the "Super Stearman" cropduster with the 450 HP Pratt & Whitney R-985 engine.
