thanksIf you have slopes then the Hillsider is a gamechanger, every field effectively becomes flat and you can do all your drilling and cutting across the slope. That said, we swapped out a MF36 for the 540 some years back and the 540 was a lot slower, lower capacity in acres or tonnes per hour than the 36 on a 16ft header. JD had promised us much higher rates than we could ever achieve even with their guy driver on it. That was a good many years back so they might have improved.
I can't speak for the Tucano and output, but we are on our second Claas now - Lexion 630 Montana - and really rate it. The build quality is excellent and the paint finish is top notch and tough.
Hope this helps a little.
