  • Patent number: 10165739
    Abstract: Embodiments relate to a tool for digging root balls of trees. The digging tool uses at least two cutting members that move in different paths for digging through the soil and cutting through a portion of the tree's roots. One cutting member moves along a substantially linear-path thereby forming a portion of a side wall of the root ball. The other cutting member moves along an arcuate path for forming a lower wall of the root ball. When the root ball is formed, the tool can be used to remove the root ball and the tree from a first location and move the tree to a second location. The size of the cutting members can be selected to form a root ball of a desired shape and size to allow the tree to continue growing at the second location.

  • Patent number: 8469126
    Abstract: Motorized vehicles having hydraulic tools as attachments are well known. Examples includes road graders, excavators, snow ploughs (and nursery equipment such as tree spades, tree movers and tree handling equipment), tractors, front loaders, and skid steers. A single hydraulic tool may be controlled by a simple manually operated hydraulic control system if the operation of the hydraulic tool is not complex. The use of “Electric over Hydraulic control” is more commonly used for hydraulic attachments with more complex functionality. A typical electric over hydraulic control system uses a bundle of wires; in which each wire in the bundle is dedicated to a particular operational feature of the attachment. These wires are prone to failure as a result of the wear and tear they are exposed to during normal use of the equipment. This, in turn, has led to proposals for the use of a wireless control system.
