There is a Encore 48in., 18hp Vanguard ZTR in the local paper for $3500. It has 100 hrs. and has only been used residentially. I am only a part-time lawn-care person( work 300-400 hrs. a year). Do you think this mower is suitable for me? Is the quality of an Encore comparable to an Exmark? Do they perform well? How fast are they? I am about to test it out in a couple of days so I'll know the majority of what I need to know, but I would appreciate your knowledge and opinion
