Not exactly a pull style tractor but not many post here anyways so hear we go. My 03 D40 has a inline 4 cyl. diesel and runs an inline p-pump style inj. pump, the 40 is the smallest of the 4cyl.'s and the 45 and 55hp tractors run the same engine and displacment so i fiqure its just in the pump tuning? Any one worked with one of these before? Its a great mid size tractor but for heavy use it could stand another 5-10 hp, any tuning tips? Thanks
