I have a chance to buy a 02 Z Master with 700 hrs for 2,800. It has a 17 hp Kawasaki and a 44" sfs deck. Has been garaged kept and appears to be in good shape. This mower is referred to a Z147 model. Is this a good price for a 02? I would appreciate any opinions on this mower as I will have to act fast. I think new it is about 6,000. I will be using this to mow my 1/2 acre that is flat. Thanks in advance for any help.
