a lot and I mean a lot has to do with how people take care of their equipment. I know another person who says his Kubota zero turn was wonderful then all the sudden was garbage. well when its parked out in the weather for three years, no maintenance, rain. snow, heat of summer. just use it and park it any mower will turn to junk rather quickly. to truly get a good deere mower, which are still made , you have to go all the way to a x500 or x700 series. and at that price point you are in the 6500 to 11500 depending on engine range. I know I wouldn't pay that if I could afford that.
