I Need the Owners Manual for a Troy-Bilt Tomahawk 2 in 1 Chipper/Shredder on the side of the machine it says Model No and next to that it says Serial NO and looks like this below. Model NO Serial NO 11360 ST W300527 I do not know what the ST is for but this is what it looks like. It has a Tecumseh Engine and the number and letters on the top of the engine are H35-45613R SER 7226B If anybody can help me it would be appreciated.
