The tree scooper is a mechanical device which shapes a root ball as a plant is being dug. The tree scooper includes an H-mount with internally mounted hydraulic cylinders, a power slider for linear motion along the H-mount and a sleeved hinge used to attach a scoop to the power slider. The tree scooper is operated by a combined rotating and back-sliding action for forming a root ball. The scoop is interchangeable for varying the size and shape of the root balls.
