Tractor runs okay at lower RPMs, at around half throttle it start sputtering. Only difference I have noticed is when key is initially turned on for glow plugs there used to be a humming noise sort of like a fuel pump pressuring up that I don't hear any more.

Welcome to the forum!

Hmmm, not sure about a fuel pump. When that happened to my tractor it was because it was starving for fuel. Cleaned the lines and replaced the filter and it was all better.

What bczoom said.
I have a G5200 purchased well used, & I thought it ran OK. But after changing fluids----and fuel filters that had loads of crud in 'em--- it ran like a new engine.
