The models of mowers I'm looking at have one of 4-5 eninges. I like the kawasaki engines the fx730 and the fx850. Recently I've looked a a scag tiger cat and a grasshopper that have the Briggs and Stratton commerical turf engine. The scag had a 30hp and the grasshopper 26hp. Anyone have any experience with these briggs engines? I just don't have a good feel on them and like the sound and feel of the kawi's. But the briggs engine mowers are significantly cheaper. the scag also comes with a Kohler command and the kawasaki engine. Any thoughts, advice, or suggestions?
