A lawn maintained with the professional-grade Exmark Navigator 42-inch or 48-inch zero-turn mower may be as close as it gets to perfection. That’s thanks to its patented fill-reduction. The Navigator generates more airflow for better vacuuming and debris collection combined with a larger diameter blower. Our professional 48-inch zero turn mower and 42-inch zero turn mower are perfect for any landscape professional who wants more controllability, responsiveness, and less hand force. Another Navigator signature trait is the higher blade tip speed for slicing grass into finer particles. Its center-discharge deck is designed with two-sided trimming that lets the operator accurately control discharge, keeping flower beds and walkways clipping-free. And the Navigator does all this at speeds up to 7 mph. So, you can Navigate a virtually perfect lawn in no time.
