The John Deere 4450 was the best-selling model of the entire 50-series line of tractors. The 4450 alone accounted for 20% of sales in the line. John Deere introduced its Caster/Action front-wheel drive system on these tractors. By enabling the tractors' front wheels to angle up to 13-degrees, sharper turn angles and larger front tires could be used.
