JD 4600 Turbo??
According to the JD literature all of the series 4000 tractors have larger cu. in. displacements as the horsepower increases, EXCEPT the 4600. The 4500 is 39Hp with 121 cu. in., and the 4600 is 43Hp with 121 cu.in. Does any body know how they get that? Do they have a turbo on the 4600?

Bill they turned up the pump. The 4600 has a higher max. RPM.
