I once designed a gear based flame-thrower using mill blades for power. It would fling out flaming objects using fireproofed arms inside a large stone casing.

In actuality, it would probably fail to actually give the leaves enough momentum to exit the barrel, and the better method of doing it would probably be either explosives or incredibly well placed catapults. It would also take hours if not days to complete, making it completely impractical for any purpose beyond showing off.
