I was planning to purchase a 32" Gravely pro steer gear driven mower in the next few days when I ran across the Ferris hydrowalk 32 today at another dealer. I tried to Ferris in his parking lot, but i'm not sure I like the single hydro. I do some mowing on hills and I'm afraid I may have turning problems as it seemed I had to physically turn the machine myself. The advantage is that the Ferris is only $300 more than the gear driven Gravely. I did a search but didn't really find too much on the hydrowalk. Any input would be appreciated from anyone who has used either of these mowers. I would prefer everyone stick to these two particular mower brands when responding. Thanks!
