Profits from the sale will be donated to the new Prince's Countryside Fund's Emergency Relief Fund which supports farming and rural crisis charities.
The special tractor is a limited edition based on the flagship 374hp Magnum 340 which Case IH has produced to mark 25 years of Magnum production at its factory at Racine in Wisconsin.
The company's UK marketing manager Charles Blessley said: "Raising money for such a worthy cause is a fitting way to recognise a landmark in the history of a tractor which has made such a valuable contribution to UK agriculture.
Victoria Elms of the Prince's Countryside Fund added: "We are delighted to have Case IH's support towards our ultimate goal of raising £1million to benefit farmers who are suffering at this difficult time."
