What -I- learned the hard way:
I would never buy another Exmark product
But more importantly I would never buy a zt again-for someone who is coming from a lt/gt they look neat and the first few times they 'appear' to be alot faster or they are faster until you take a good look at your lawn and it suddenly dawns on you that you cannot make a zero turn on turf without damaging it, NO ONE can make a zt on grass without damaging it.
Yes the zt, or the more commercial zt mowers do have incredible forward speeds but the rapid miles per hour are useless unless one is on a 5 star golfcourse green-or unless one is fortunate enough to have a chiropractor in the family or as a good friend; for the average home turf conditions you will find yourself mowing at reduced lawn tractor speeds AND you will quickly discover that turning a tractor of whatever turning radius is no more time consuming than making three point turns on your smurfy new zt.
The ONLY area one will truly benefit from a zero turn is if you have an incredible number of 'gotta go arounds' in your yard, but it would have to be an awful lot of obstacles.
Lastly, I believe that Briggs has, on their website, a real good blurb on why the zt application is such a hostile one for any engine, and why they went to the 'new' cyclonic air filtration. But even the Deere spec ELS with the neat oil cooler and funky 'cyclonic' filter is still a Briggs. The ELS or 'Professional' is an Intek-ask the dealer to see the manuals and it is listed plainly as such. BUT in fairness to Briggs, while I will never every own another, many tens of thousands of other owners would.
Just one guys opinions.
Sure wish I would have seen all those Cub Cadet pictures on that web site BEFORE I went the Exmark zt route-a horizontal Kohler Command out of 'harms' way up front UNDER the hood, drive shaft, monster cast iron drive, six quarts of juice, with external spin on hydro filter, real bolted on rear wheels----
And think about this, just what good are cup holders on a zero turn?
For me, buying a zero turn; in the end, made zero sense.
