Ok, so we know the ride is rough on these things, but DANG! I mowed a flat, but very rough terrain today and thought I was going to destroy the new Z. I just don't understand why Exmark cannot come up with frame suspension to absorb this impact. My mower bounces so hard it sounds and feels like I'm tearing it up. Mind you, I'm only going like 3 or 4 mph over the roughest spots and it's crazy. Are these mowers tough enough to hold up under these conditions. Frame, bolts, springs, bushings, etc? I just hate feeling like I'm destroying a brand new mower, but I have to get the job done. Anybody else out there feel me?
