Twinkle New Holland have changed a lot of things, some in minor ways and some in quite a big way. To give you an idea of what they've changed in brief:
Engine, Cooling system, Fuel tank, Grain tank, New Cutterbar, Seives, Rotor covers, Residue management system, Wheel and Track options, Intellicruise, Grain Cam, Visability Options, In Cab Screen and since this lot means that this is a wole new machine they have changed some of the tin work a bit too.
