It has just 327 separation hours on the clock and is described by dealer principal Roger Vater as being in immaculate condition.
"With so few hours up, it is still a new machine," he said.
Mr Vater said the CR970 was sold new by his dealership and had been fully serviced by his team of trained technicians.
"This combine is complete with a 10.6m MacDon FD70 Flex Draper front with a cross auger making it most suitable for harvesting all types of crops including lentils and peas," he said.
"It has a 11,630 litre grain tank, is fitted with both a yield and moisture meter and is powered by an NH/Iveco 276kW engine and features a hydrostatic drive system.
"I believe at our asking price of $440,000 inc GST it represents a top buy for someone looking for a used machine that is virtually still new, with a saving of around $250,000."
Mr Vater said New Holland was the pioneer of the rotary combine design.
"Its system uses two rotors, spinning in opposite directions to move the crop rearward in a spiralling motion against threshing and separating grates that surround the rotors.
