Without question, the suspension on a Ferris makes for a really nice ride. Looking past that, I believe the Deere outshines it in build quality, dealer support, parts replacement, cut quality, better deck and overall reliability. My two biggest complaints with Deere is the limited engine options in their commercial line and the ride. Running Tweels does help, as does Z Glides. The armrests on the Deere need to be upgraded, not near comfortable enough in my opinion. The 7 Iron deck is super strong, cuts beautifully and disperses clippings like no other. The only other deck that comes close in my opinion is the Scag Velocity Plus deck.
