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.
Claims13
An apparatus for forming a root ball comprising:
- (a) a frame that is operatively couplable to a support vehicle;
- (b) at least one arm that is connected to the frame comprising:
- (i) a first tower that is supported by the at least one arm;
- (ii) a first cutting-member that is supported by the first tower and movable between a retracted position and an extended position along a substantially linear-path;
- (iii) a second tower that is supported by the at least one arm;
- and
- (iv) a second cutting-member that is supported by the second tower and moveable between a retracted position and an extended position along an arcuate path, wherein in operation the second cutting-member moves along the arcuate path to cut a lower wall of a root ball;
- wherein the first cutting-member and the second cutting-member are movable from their retracted to extended positions independently of each other.
