Mighty Macs are famous for their heavy-duty systems. The manual emphasizes these "Golden Rules":

If your model is self-propelled or uses a belt drive, check the belt tension frequently. A loose belt is the #1 cause of lost power.

Before searching, look for the Model Number and Serial Number on the metal plate (usually located on the frame or the chipper chute). You will also need the separate manual for the engine (Briggs & Stratton, Honda, etc.), as MacKissic doesn't manufacture the engines themselves. 2. Essential Safety (The "Must-Reads")
