What is the overall opinion of the Gravely 34 ztr? Owners would you buy it again? I have read that its really heavy and leaves a lot of ruts? How does it run on small lawns? What type of grass do you cut with it....I would be on st.augstine. I am still stuck between this mower and a 36"exmark tt hp with a sulky hopefully I wont have to post anymore about mowers, since I am even getting sick as thinking about them!
