This spring, we got a Toro zero turn, 50" deck, 20 hp Kawasaki engine. My wife does all of our mowing, says it's her recreation, and she'd been using a 54" Poulan with a 24 hp Briggs engine.
The Toro cut her mowing time in half, and she commented on how nice it rides. No suspension, just good springs under the seat.
I haven't used it much, myself, but I like the sound of than Kawasaki engine.
It was kinda funny. We walked into Home Depot one Saturday afternoon on a completely different errand. We'd always talked about getting a zero turn, but never did. HD had this left over last year's model with $1,000 off the price. On a sale item, I didn't think my 10% military discount would apply, but the salesman checked it out, and the computer took another 10% off the price. By then, it would have been hard to walk away from it.
