"High gear is more of a load for a longer duration and the fuel required would outrun the fuel that is able to flow through a restricted fuel filter. So with low RPMs it may run fine and when you put it under a heavier load requiring more fuel it starts starving for fuel. Deisel engines require compression, fuel, and air. I would also check the air filter for good measure. If it is starving for air it puts out more black smoke(unburned fuel) as well as not as much power.

I completely agree..same thing has happened to me..my tractor was fine bushogging all day and then on a 5 mile trip on the highway it started bogging down...I replaced the fuel filter and bled the lines and problem was solved.
