I am considering a used Gravely 34z. Is there anything specific that I should look for when going to see one (problem areas or areas of weakness). I would also like to know how much would a used one in your area go for and also what should be the most hours to consider. I don't want to buy a used one and inherit someone else's problems but I am not in a position to purchase a new one at this time. With proper maintenance what is usually the life expectancy of the machine, how many hours have you logged on your Gravely before needing costly repairs. Thank you, and sorry for all of the questions. I am just concerned because this will be the first piece of equipment that I consider purchasing used.
