The bevel 58 of the tooth, while rather obtuse and not forming an edge capable of cutting into the tree trunk to any great degree, nevertheless provides for shedding the bark of the tree trunk so that the tooth can gain a firm purchase in the tree trunk, and will not slide upwardly therealong.
Such material of course accumulates to a large volume very rapidly, and then tends to spill rearwardly over the upper edge of blade 14. Asking Price --- $21,000 GST We advertising this machine for our customer, Please call Vince @ (Cl.
A higher point of force application would provide better leverage and permit felling of bigger trees with the same tractor power. The spacing of tooth 52 at a greater distance ahead of the tractor largely solves this difficulty. Excellent choice for clearing Lantana , wattle , privot and regrowth .

Further operative details of the tractor are no-t shown, not being pertinent to the present invention and in any event being well-known to those familiar with the art. Other objects are simplicity and economy of construction, etiiciency and dependability of operation, and adaptability to be attached to pre-existing bulldozers with a minimum of alterations or additions to the latter. l is a partially schematic side elevational view of a crawler-type tractor having a tree pusher attachment embodying the present invention mounted operatively thereon, FIG. Of course, with the tree pusher attachment shown, if the tree should be limber and bend considerably before yielding, so that the point of engagement of tooth 52 against the tree is lowered substantially, it may be necessary to extend hoist 30 slightly in order to prevent the rearward end of the tractor from being elevated above the ground. 2, and also the serrated edge is vertically bevelled as shown at 58 in FIG. If the tractor is close to the tree, its considerable weight tends to prevent the roots from tearing free, and thus tends to defeat its own purpose. What I claim as new and desire to protect by Letters Patent is: 1. The advantages of the tree pusher attachment over use of the blade 14 directly as a means for felling trees are considerable. Located in Coolum Beach, Sunshine Coast Queensland 4573. Also, nearly any bulldozer can be adapted to receive the tree pusher attachment, ears 42 and clips 60 .being the only additions necessary to accommodate the attachment.

The operation of the attachment is believed obvious. 16, 1968 A further object is the provision of a tree-pusher attachment of the character described 4which serves the additional function of a hold-down member the bulldozer is used to clear brush and the like, preventing said brush from passing rearwardly over the upper edge of the bulldozer blade. Fourth, the tree pusher attachment is extremely simple and convenient to attach to or remove from the bulldozer. • Rebuilt motor 200 hrs ago, new paint 12 months, 2 new batteries, vgcGood station dozer.

No. Each push bar is pivoted at its forward end, as at 20, to the rearward side of blade 14, pivots 20 being horizontal and coaxial, and is pivoted at its rearward end, as at 22, to the associated side rail 12 of the tractor frame, pivots 22 also being horizontal and coaxial. Very 2, FIG. Therefore, if said load is to urge treads 5 flat against the ground for improved traction as described, it will be apparent that a rearward extension of a plane containing blade 52 and pivots 22 must intersect the ground level at a line intermediate sprockets S and 19 of the treads. • Tree pusher fitted. TREE PUSHER ATTACHMENT FOR BULLDOZERS 2 Sheets-Sheet C Filed May 7, 1965 INVENTOR W//f'am A. Jamas; .//f BY Z Afro/wey. Welded or otherwise fixed to the lower surface of each beam 40, intermediate its ends, is a hook member 46 constituting in essence a solid block. l, FIG. Accordingly, the principal object of the present invention is the provision of a tree-pushing attachment for bulldozers which overcomes all of the above described disadvantages, in that it provides for application of force to the tree trunk at a higher elevation above the ground, provides that the tractor may be positioned at a greater distance from the base of the tree, and provides that a greater component of the reactive force when pushing a tree will hold the tractor treads firmly against the ground, than is possible when using such a bulldozer for this purpose without such attachment.
