Abstract
A tree pusher for safely felling trees. The tree pusher controls and determines the direction in which the tree falls, using a base, a frame, a detachable head which engages the tree trunk, and an extendable screw-type trailer jack that is repairable/replaceable during operation and capable of bearing the weight of a large tree, for urging the frame and the head against the trunk of the tree. For use on uneven ground, the tree pusher is provided with a base extension. A chain is used to connect the base of the tree pusher to the trunk of the tree, to prevent movement of the base when the jack is activated. The tree pusher can be readily moved to the job site, and can be used on any type of terrain, including hard surfaces, and for any type of tree, including trees with rotten wood.
Claims14
A tree-pusher for felling a tree, the tree-pusher comprising:
- (a) a base;
- (b) a frame, mounted on the base, the frame comprising first, second, third, and fourth rectangular tubes having first and second ends, the first tube being pivotally connected to the base, the second tube being disposed in the first tube, the third tube being constructed and arranged to slide over the second tube, and the fourth tube being constructed and arranged to be inserted in and pinned to the third tube;
- (c) a detachable head constructed and arranged to be disposed in the fourth tube, to attach itself to a trunk of the tree, and to detach itself from the frame of the tree pusher and remain attached to the trunk of the tree when the tree falls;
- and
- (d) a screw-type trailer jack which is attached to the frame, which is extendable, and which is capable of bearing the weight of a large tree, for urging the frame and head of the tree pusher against the trunk of the tree.
A tree pusher for felling a tree, the tree pusher comprising:
- (a) a base for elevating the tree pusher when the tree to be felled is on ground slightly above level of ground supporting the tree pusher, the base comprising a first plate 60, a second plate 32i, and third and fourth parallel plates 60a and 60b spaced apart and fastened perpendicularly to the first plate 60;
- (b) a frame, mounted on the base, the frame comprising first, second, and third rectangular tubes having first and second ends;
- the first tube 42 being pivotally connected to the base, fastened to the second plate 32i and disposed in the second tube 44;
- and the third tube 46 being constructed and arranged to be inserted in and pinned to the second tube;
- (c) a detachable head constructed and arranged to be disposed in the third tube 46, to attach itself to a trunk of the tree, and to detach itself from the frame of the tree pusher and remain attached to the trunk of the tree as the tree falls;
- (d) a screw-type trailer jack which is attached to the frame, which is extendable, and which is capable of bearing the weight of a large tree, for urging the frame and head of the tree pusher against the trunk of the tree;
- and
- (e) a fourth rectangular tube 62, disposed between and pivotally attached to third and fourth parallel plates 60a, 60b and to the first plate 60, and extending through the first and second tubes 42 and 44.
A method for felling a tree, the method comprising the steps of:
- (a) providing a tree-pusher having a base, a frame, a detachable head which engages the tree trunk, and a screw-type propeller trailer jack for urging the frame and the head against the trunk of the tree;
- (b) securely connecting the base of the tree-pusher to a trunk of the tree;
- (c) attaching the head and frame of the tree-pusher to the trunk of the tree;
- (d) cutting a notch in the trunk of the tree above the point of attachment of the tree pusher and on the side opposite the attachment of the head and frame thereto;
- and
- (e) using the jack to urge the head and frame of the tree-pusher against the tree trunk to fell the tree, detach the head from the frame of the tree pusher, and leave the head of the tree pusher attached to the trunk of the tree.
