I just went thru this process and there is no clear winner. They ALL have their benefits and disappointments. Budget determines a lot. I would stay away from the entry level models. I have 1.3 acres with some hills. I looked hard at Ferris, ExMark, John Deere, Toro, Scag and Kubota. Most of the ones I felt would work for me were in the $5K range. Of those most were pretty comparable......similar deck size, similar seats, similar motors. Every salesman was confident their units were the best and would outlast my needs. I finally ended up with a Simplicity Courier XT.........the XT is a upgrade from the Courier models. It is a blend of Ferris & Simplicity technology. ( Ferris & simplicity are owned by Briggs& Stratton). They all claim to have the best cut and most of them claim to stripe very well. I'm sure any of those brands would work for me but I chose the Simplicity Courier XT because it also had the comfort ride suspension springs dand a full width rear deck roller for the striping. Go sit on a few of them and take a test ride if you can. Look at how the deck is mounted and supported and how it is leveled. Look at the hydro's and see if they are serviceable ( can you change the fluid). I doubt the motor brand makes much difference on any of them as they all have similar performance in the 20-25hp range. EFI is a nice option. For residential use of 50-100 hours per year, I doubt you will wear it out if you do normal maintenance and don't overload it. I can pull my tow sprayer, aerator, cart, de-thatcher and spreader just fine. I'm sure the others can too. None of them were promoted as great mulching machines.......yes they will mulch....but mulching brings up a lot more issues such as cleaning the underside of the clogged deck, mulching blades brand, wet grass, tall grass, short cutting and double cutting. And keep in mind ....you don't have to mow at 10mph........slow down and let the blades do their thing and enjoy the results. Goo luck!
