I'm thinking of buying a used Ferris Hydro-walk 36 I ran across recently, and I'm wondering what I should look for in terms of wear & tear, common problems, etc. Also, what do you think of this mower? I need a mid-size to cut (and bag) zoysia and bermuda. This one has a 14 hp Kawasaki, a bagger, and a Velke. The seller wants $1500, and the machine looks to be in "fair" condition. Thanks for your comments.
