This excavator is due to be replaced as it is very tired and runs like it has Parkinson's disease. It does NOT operate very smoothly. Other operators try and they're like why is this thing so herky jerky?
You need a few days on it to understand it's complexities. Notice how I don't lose much product between the car and the Lego blocks.
The gravel is for cement to a build a sky scraper downtown.
And I'm driving the train by remote from the excavator seat.
Fun with my train set:
