I found the video to be very one sided , as you'd expect being an Exmark dealership. The Walker has many benefits over the Navigator that they chose not to mention. I now see why the Nav. is heavier. I listen to sales people about the facts but when it comes down to claiming that there product is better, I don't listen so much. They do not use the machines like we do. If they are lucky, they get to demo it for someone for a short while. I looked at both since I have both dealerships close by. Do I think that the Nav. is a good machine? Yes. But when it came down to it for me, the Walker won hands down.
