I need an approximate value on a used Kubota g1800 with a 48" deck in very well maintained condition with about 1000 hours. How well do these machines finish cut? How many hours is the 3cyl diesel engine likely to last? What are the most common maintenance and or costs associated with a machine of this age? Are there snow blowers still available or can they be interchanged with the current models? I apologize for all the questions. Pleas forward a reply. Thank you.
