Navigator

There’s mowing. There’s manicuring. And then there’s navigating.
Nothing is perfect. But a lawn maintained with an Exmark Navigator may be as close as it gets. That’s thanks, in large part, to its patented fill-reduction. Combined with a larger diameter blower, the Navigator generates more airflow for better vacuuming and debris collection. And this year’s model is perfectly suited for any pro who wants even more controllability, responsiveness and less hand force. Another Navigator signature trait is the higher blade tip speed for slicing grass into finer particles. Then, its center-discharge deck designed with two-sided trimming 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.
