I am considering purchasing a ztr in the near future. I currently use a 48" scag hydro wb with a 14 kohler, and sulky as my main unit. The ? is will a Z be more effcient, better job, and worth the extra $$? I am a small LCO that mows part time, 15 weekly accounts @ appr. 12hrs from start to finish mowing only, and not all the other little odd jobs they have me do. I am currently turning away new customers do to work load, I work 3rd shift at the post office full time also. If I purchase a Z it would be a 48" or 52" have not decided yet. Would my best bet be to just demo a couple of units on different days to see? Thanks for your advice.
