If the old Farm equipment had enough things what the new equipment has, then we can buy the old ones. We know always latest machinery have latest technology things, so buying latest is the best for us.
Latest farm equipment are coming as per our requirements like low power adoption, fast processing with less labor.
I would suggest to go with new ones as used always the parts would get damaged froim the earlier user. Most people sell their old parts because the product got damaged or their is new type available in the markte.
Do you really buy a used one for your sake?
