A lot of brands to wade through and some aren't available in all areas. It makes me wonder how industrialized or over-the-counter the lawn mower business really is. To build a mower order the engine, transaxles, pulleys and bearings, fabricate a frame and a deck. Bolt it all together, add some tires, belts, levers, blades and voila. Well... obviously that's over simplistic but still with several central manufacturers for things like engines (Briggs and Straton, Kawasaki, etc...) and transmissions (Hydro-Gear) and I'd guess other parts it does seem fairly cut and dried. Let me know if I'm missing any manufacturers.
