I have 4 acres that has ditches and some hills (not real steep). I am looking for a good zero turn that is easy to use and doesn't cost an arm and a leg. I am a female that does most of the mowing. My husband would like to get a commercial grade zero turn. We have been looking at Toro Z Masters and Cub Cadet Tanks. But then looking at Consumer Reports, they are not all that great. Any suggestions out there?? Right now we are using a smaller Craftsman lawn tractor, not real good in the ditches and I am afraid of tipping over.
