  • Patent number: 6253690
    Abstract: This invention relates generally to an apparatus and a method for excavating and transplanting a live tree. The invention relates more specifically to equipment which utilizes curved ground piercing blades moveably supported on a ring assembly positioned around a tree to be transplanted, the blades being forced and guided down into the ground to completely encompass a tree root ball which can thereafter be lifted out of the ground and transported for subsequent transplantation. Both the apparatus and the method facilitate the excavation and transplantation of trees with low limbs and crooked trunks to and/or from uneven or sloping terrain, and may be utilized with any of the prime movers of adequate towing capacity available at an excavation site.
