You will enjoy watching them work great.Lucky the engine didn't run away by drinking it's own oil through the pcv system. Don't ask how I know.So that’s how the back of the machine get scratched up.Saw the dipper ram break out once…..should have knocked down more upper wall for a bigger ramp.Stupid idea when you could take more wall out and build a ramp. One little slip of the bucket and it goes over. You ever bumped your head on a machine like this? Not fun
