IHC gives 9-5/8 mph (9.625) at 1400 rpm in 4th gear. Fifteen mph is 1.558 times 9.625. 1400 x 1.558 = 2182 rpm.
Can the engine take it? I don't have any idea, but I expect manufacturers were really cautious when these tractors were made. After all, the previous generation tractors topped out between 1000 and 1250 rpm, depending on the model, and they had splash lubrication.
