ABSTRACT:
An end grapple for use on loader tractors in nurseries to load and unload trees and shrubs onto and off of trucks and the like includes a grapple head with three fingers. Two of the fingers are fixed to the head and extend generally straight, while the third finger is curved and is mounted for pivotable movement to grip the earth balls of the trees and shrubs. The pivotable finger is movable by a hydraulic cylinder. The grapple head is mounted on the end of a rotation shaft that is driven for rotation by a hydraulic drive motor to permit trees in any orientation to be grasped by the grapple. A quick release connection permits easy and fast changing of the grapple head with other equipment.
