This model (RD 130) with a 5.5" till depth probably isn't the best model to use for this type of demonstration but you get the idea of what these machines can do. Some grading may be necessary depending on jobsite conditions. This demo is on an ungraded site. Watch the other videos to get a better idea of full capabilities.
Standard duty models till at a depth of 6.5" and the RX agricultural units till at 9".
