The 600 Series has the 134 CID OHV Gas Engine; with LP and 144 diesel as options. The "2" defines the model as: "FOUR SPEED TRANSMISSION, NO PTO, NO 3-POINT LIFT". The 3rd digit designates: "0" as Hundred Series 1955-1957; and "1" as "01" Series, 1957-1962. No one can pinpoint a value on any tractor without seeing it up close and personal, but know too that the market value on antique tractors has declined over the past ten years or so as the interest has also declined. FORD 621 models were used as the basis for a later style of Moto-Tug. Like any vehicle, there are many deciding factors to consider when buying used.
