The John Deere so far has been really good for the time I've used it which is very little. The best thing I like about it is that I have hills and with its steering ability it's great for mowing around trees. The hill side are also no problem. With a regular zero turn not a safe thing to do is mow hill sides so I was skeptical but this tractor does this with ease.
The negative it is not the best at picking up leaves. They have the tendency to roll in front of the deck and some blow out the sides. The bagger does great for grass not so good for leaves. If you use it for leaves expect to clean the tube out when you empty the bags on the plus side bagger carries well and seems to be made very well. I know this because I hadn't got use to the steering which is very odd till you get used to it. So beware of your bagging attachment when getting close to anything. All in all so far its been great and will update this as it goes.
