I suggest you wife, like mine, will be very comfortable and safer than on any other brand using the CC 160 or 154. I would NOT suggest going to a higher deck size for basic consumer use. 60" is the sweet spot to reduce scalping and to maneuver around objects like trees, etc.
Make no mistake that Exmark discontinuing steering wheel zero turns is no reflection on their capability; rather the true pro users who are cutting lawns ten hours/day are used to and prefer the lapbars since they've been in use for so many years. And I suspect they look at the steering wheel mowers as less 'manly'. :confused3:
Trust me, I've put my Pro-Z 160 through its paces last season and it performs flawlessly. It out cut my Scag 62" deck ZT in every category. The only thing I suggest keeping an eye on is not allowing grass to accumulate on the rear wheel motors. CC uses fans to keep them cool, and the CC is NOT a water cooled and fan cooled radiator system like the Scag Wildcat I had. BUT the Scag with 12.xx buschel bagger was over $13,000 back when it was new around 2008-'09. I bought it used for $8K and sold it for $4K to pay for most of the new CC cost. I don't see the lack of water cooling to be a problem so long as one maintains the fans ability to do their job. After all, most buying one of these aren't going to be using them 10 or more hours every day of the week, though I'm confident they would hold up if properly attended to.
PM me if you have any specific questions.
Oh yeah, almost forgot, there is cruise control for forward, and though I don't use it often it's a nice feature to have, just in case.:thumbsup:
