Also, there's not much yellow, which makes sense when you realize how much of the part volume goes into the arm and treads. The first one is for building the arm with the shovel and the other ones are for building the rest of the vehicle; the bodywork, the suspension and the tracks. Sure, the arm is a similar function, but the rest of the vehicle looks great and completely different. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. But I'm into LEGO for 48 years and I dislike that I almost spend as much time in turning pages as actually adding pieces as the instructions are so dumb these days.

I too am surprised at how many people don't mind the fact that the windscreen can barely be seen through. I'm not a fan of System parts in Technic sets so thankfully they've been used sparingly, for the seat in the cab and to add additional texture and shaping to the bodywork.This is directly controlled - the knob on the back and one on the right side each drive a segment of the arm.
