I have always wanted a ferris for many years because of the nice suspension they have. I have tried the suspension seats . They help a little. Now I finally broke down and bought a 3100z two months ago. It has the best ride and you feel good about mowing. At the end of the day it just amazes me. Not only is the cut beautiful but I don't slow down on uneven turf. And the machine will not scalp. I will be a ferris guy for life . If u don't get one u will never know how nice they are. I laugh at the other guys now that are bouncing out of there seat .
And no machine will match the comfort of the ferris. I have a suspension seat on mine and it rides like a caddy floating on a cloud of grass.
