Good info, I really apreciate the fuel #s orange. That is what I was looking for. As earlier Im looking at MX5100 HST FEL and R4. Sounds about like yous. You had any concerns or things to be aware of? I saw an earlier post about the rear tires being too wide if using the FEL for grading. It said the tires were wider than the FEL loader so you would leave tire tracks if you back dragged with the bucket. Not a big concern but something to remember.
