I'm involved with my Son's rec. league where he plays baseball. We have 4 fields and quite a bit of other grass areas we mow. The areas that are not fields are on some good little hills. We are fixing to get a new mower, our old rider(J.D.) is playing out. We are looking at a Scag priced to us by a local dealer at around $6000. I like it and Kubota. With the info. given, what are you alls opinions on the best longest lasting ztr to purchase for $5500-maybe $7000?
