I'm not sure I understand the question?
What model number of baler do you have, and is it run by an engine or a pto shaft? What is the 'both' in your question? What model of baler do you have?
Most older NH balers in running condition go for $500-$1000, depends on their condition can be more or less and the time of year. We are getting closer to the end of the season, will sell better in Feb through May....
