Looks good, Ferris makes some pretty good quality stuff from what I've seen in the past. I've never owned one personally, but have worked around them and used them some on a couple of Golf courses I worked on wayy back in the day.
I recently bought a new mower also, but it's a 'stand on' made by Bad boy mowers. Figured I'd give them a try. Haven't been around nowhere near as long as Ferris though, but so far I'm impressed.
I looked at them too, like the suspension idea.
I did a suspension seat recently after 9 years of regular rubber mounted. Big Difference.
I'm sure you will love the ride. They looked like good mowers.
I bought a 72" ISX3300 last year and it's awesome.
I love to cut grass anyway, and with the Ferris my lower back actually feels better after I cut the grass. On my old Troybilt mower I'd have a hard time walking for several days after cutting the grass.
With the suspension you will get some side scalping if you go too fast into a turn.
