Starting a diverse farming enterprise I'm looking for a mid-powered tractor that can do basic yard duties but have the capability of doing most arable tasks as well. I'm fairly set on a JD 6930 premium 50k however the prices are crazy at the moment. Proving the head gasket and ERG are changed has anyone run this tractor successfully for long hours and still have good availability of parts or should I look for a newer 6 series with lower horse power?
