Not sure if this is the right forum, but i have been looking for a used Gravely 44/144/148Z and even some of the 200 series ZTR's to use for my home that sits on a few acres. i came across a 250Z with 500 hrs on it, 23hp Kawasaki, hydraulic deck lift, etc. they are asking $3500... i was wondering if this is a good price or not? i'm not sure what may have been replaced on it (hydro pumps etc), and can anyone work on these machines or does it need to be a Gravely dealer? i don't have one close by... thanks in advance for your suggestions.
