Here's my tale, Ive been in the business over 15 years and did fine with bobcat walkbehinds for a long time. but as you guys know you can only step in so many holes before you get sore. So I bought a ZTR200 23 kawi. A dependable machine, it didn't cut like my 48 wb's ( deck dosn't folow the ground enough0 so after 3 seasons I tried and bought a Walker 25hp. It mows awesome with either the 52 sd deck or the ghs deck. However, roughest ride I everhad and slow to boot. I'm keeping this machine but want to know how the Ferris suspension machines hold up and cut. do they really follow the terrain? I tested a Gravely 310 yesterday on hilly ground and wouldn't buy one for the way it works there. Speed up kit and suspension seat are on the way for my yellow sweet heart now.
