Quote "Here's a picture from the NH site that shows them working on dirt and notice the pads."
If you look closely, you can see that the picture was done very nicely by a marketing dept. I don't see any dirt on the back of the bucket. The tires are relatively clean. Even the side of the bucket is clean. I wouldn't be surprised if someone filled the bucket with dirt with a shovel to make the picture look nicer. I have used my backhoe about 15 hours in the past month alone and I can guarantee that mine is very dirty compared to the one in the picture.
NH did nothing wrong in the picture, but it is obviously not a picture of a real worker doing real work. The cameraman and model may have never seen a tractor before.
