Factual narrative

While landing his helicopter at a cattle feeding lot, the pilot failed to maintain clearance from a piece of farm equipment that had been parked near the location that he chose to land at. While less than 10 feet above his landing spot, the pilot inadvertently allowed the tail rotor of the helicopter to impact the piece of equipment.
