Claims
- 1. A tree-removing device comprising a first blade adapted for location in close proximity to a tree; a power blade frame pivotally carried by said first blade and a root cutting blade extensible and retractibly carried by said power blade frame for selectively extending from said power blade frame into the ground and cutting the roots of the tree in operational mode and retracting inside said power blade frame in retracted mode; and a jack frame pivotally carried by said first blade; a jack foot extending from said jack frame; for engaging the tree; a mast extensible and retractibly carried by said jack frame; fluid-operated cylinder means mounted on said mast for pivoting said mast, said jack frame and said foot with respect to said first blade, and stabilizing arm means pivotally carried by said mast for engaging the tree above said jack foot and stabilizing the tree responsive to pivoting of said jack frame and said jack foot and removing the tree from the ground.
- 2. The tree-removing device of claim 1 wherein said stabilizing arm means comprises a stabilizing arm pivotally attached to said mast; an extension arm extensibly and retractibly carried by said stabilizing arm; and a tree-engaging plate provided on said extension arm for engaging the tree.
- 3. A device for attachment to a land vehicle and removing trees from the ground, comprising a first blade attached to the land vehicle; a power blade frame pivotally carried by one end of said first blade, and a root-cutting blade extensibly and retractibly disposed in said power blade frame for selectively extending from said power blade frame and cutting the roots of the tree; a jack frame pivotally mounted substantially in the center of said first blade; a jack foot extending from one end of said jack frame for engaging the tree; a mast extensibly and retractibly extending from the opposite end of said jack frame; and stabilizing arm means pivotally carried by said mast for engaging the tree above said jack foot and stabilizing the tree, whereby said first blade is first maneuvered around the tree with said root-cutting blade extended from said power blade frame for cutting the roots of the tree and said first blade is then maneuvered in close proximity to the tree, said jack foot and said stabilizing arm means are engaged with the tree and said jack frame and said jack foot are pivoted with respect to said first blade to remove the tree from the ground.
- 4. The device of claim 3 wherein said stabilizing arm means comprises a stabilizing arm pivotally attached to said mast; an extension arm extensibly and retractibly carried by said stabilizing arm; and a tree-engaging plate provided on said extension arm for engaging the tree.
- 5. The tree-removing device of claim 3 comprising a blade-operating, fluid-actuated cylinder provided in said power blade frame and attached to said root cutting blade for selectively extending and retracting said root cutting blade in said power blade frame.
- 6. The tree-removing device of claim 4 comprising a stabilizing arm, fluid-actuated cylinder provided in said stabilizing arm and attached to said extension arm for selectively extending and retracting said tree-engaging plate in said stabilizing arm.
- 7. The tree-removing device of claim 6 comprising a blade-operating, fluid-actuated cylinder provided in said power blade frame and attached to said root cutting blade for selectively extending and retracting said root cutting blade in said power blade frame.
- 8. The tree-removing device of claim 3 comprising a mast-elevating, fluid-actuated cylinder provided in said mast and attached to said jack frame for selectively extending and retracting said mast in said jack frame and locating said stabilizing arm means in a selected position with respect to the tree.
- 9. The tree-removing device of claim 8 wherein said stabilizing arm means comprises a stabilizing arm pivotally attached to said mast; an extension arm extensibly and retractibly carried by said stabilizing arm; and a tree-engaging plate provided on said extension arm for engaging the tree.
- 10. The tree-removing device of claim 9 comprising a stabilizing arm, fluid-actuated cylinder provided in said stabilizing arm and attached to said extension arm for selectively extending and retracting said tree-engaging plate in said stabilizing arm.
- 11. The tree-removing device of claim 10 comprising a blade-operating, fluid-actuated cylinder provided in said power blade frame and attached to said root cutting blade for selectively extending and retracting said root cutting blade in said power blade frame.
- 12. A device for attachment to a bulldozer and removing trees from the ground, comprising a bulldozer-type blade attached to the bulldozer; a power blade frame pivotally carried by one end of said bulldozer-type blade and a root-cutting blade extensibly and retractibly disposed in said power blade frame for selectively extending from said power blade frame and cutting the roots of the tree; a jack frame pivotally mounted substantially in the center of said bulldozer-type blade; a curved jack foot extending from one end of said jack frame for engaging the tree; a mast extensibly and retractibly extending from the opposite end of said jack frame from said one end; and stabilizing arm means pivotally carried by said mast for engaging the tree above said jack foot and stabilizing the tree, whereby said bulldozer-type blade is first maneuvered around the tree by operation of the bulldozer, with said root-cutting blade extended from said power blade frame for cutting the roots of the tree and said bulldozer-type blade is then maneuvered in close proximity to the tree, said jack foot and said stabilizing arm means are engaged with the tree and said jack frame and said jack foot are pivoted with respect to said bulldozer-type blade to remove the tree from the ground.
- 13. The device of claim 12 wherein said stabilizing arm means comprises a stabilizing arm pivotally attached to said mast; an extension arm extensibly and retractibly carried by said stabilizing arm; and a tree-engaging plate provided on said extension arm for engaging the tree.
- 14. The device of claim 13 comprising a blade-operating, fluid-actuated cylinder provided in said power blade frame and attached to said root cutting blade for selectively extending and retracting said root cutting blade in said power blade frame.
- 15. The device of claim 14 comprising a stabilizing arm, fluid-actuated cylinder provided in said stabilizing arm and attached to said extension arm for selectively extending and retracting said tree-engaging plate in said stabilizing arm.
- 16. The device of claim 15 comprising a mast-elevating, fluid-actuated cylinder provided in said mast and attached to said jack frame for selectively extending and retracting said mast in said jack frame and locating said stabilizing arm means in a selected position with respect to the tree.
