tree pusher for dozer

5. This is important since when felling a tree by this method, the trunk itself 4generally does not break. Instead, the tree roots break beneath the ground level, often at some distance from the trunk, and tear upwardly out of the ground between the tree trunk and the tractor. Optional high tensile steel Cutter Bar available for installation at ti.... Australian made 300-400hp Dozer Excellent design combining strength and efficiency. A heavy duty, multi purpose, tyned agricultural implement which can till the soil to make it ready for planting simultaneously with eradicating the sticks and the roots from the soil. Of course, ordinary bulldozers are already commonly used for this purpose without benet of attachments, simply by placing the bulldozer blade against the trunk of the tree and advancing the tractor to apply horizontal force to said tree trunk. What I claim as new and desire to protect by Letters Patent is: 1. 2, and each has a mounting plate 50 rigidly welded thereto. 4 is an enlarged fragmentary sectional view taken on line IV--IV of FIG. 37-2) ABSTRACT F THE DISCLOSURE A tree pusher attachment for a tractor having a bulldozer constituting a bulldozer blade extending horizontally in front of the tractor by means of pusher beams attached at their forward ends to said blade and connected at their rearward ends to the frame of the tractor for pivotal movement on a horizontal transverse axis, said tree pusher attachment comprising a second pair of pusher beams pivoted at their rearward ends respectively to lsaid lirst pusher beams, on a horizontal transverse axis, and extending forwardly of said bulldozer blade to rest on the upper edge thereof, and means attaching said second pair of pusher beams to said bulldozer blade. Our stick .... Australian made 200-275hp Dozer Excellent design combining strength and efficiency. Most efficient method of land clearing when both trees and roots have to be removed. United States Patent O 3,377,724 TREE PUSHER ATTACHMENT FR BULLDOZERS William A. Jones, Jr., 710 S. Spring, Nevada, Mo. New. 2, and also the serrated edge is vertically bevelled as shown at 58 in FIG. Such material of course accumulates to a large volume very rapidly, and then tends to spill rearwardly over the upper edge of blade 14. 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. Now you are ready to take on any job. 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. Rakes are recommended if the tractor will be used for tree removal and stacking, in addition to pushing trees. CATERPILLAR D5G XL Dozer Stick Rake & Tree Pusher DOZATT StickRake to suit Cat D5 Bulldozer, Wholesale price-----$12,500 +GST. While often used for pushing materials out of an area, there are attachments to get the job done and expand into other uses. 2, to permit the beams to be moved forwardly over the blade enough to permit hooks 46 to engage said blade as previously described. Each turnbuckle is pivoted at its upper end to the rearward face of blade 14 at a point above pivot 20, as at 26, is pivoted at its lower end to the associated push bar 18 at a point spaced rearwardly from pivot 20, as at 28, and is of course adjustably extensible in length. The forward ends of pusher beams 40 are spaced apart as shown in FIG. Multiply tractor horsepower by leverage so that large trees are quickly pushed over and root systems exposed for easy removal. 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. Therefore, when pushing trees with blade 14, there is a pronounced tendency for tread chains 6 to move the tractor forwardly under pivots 22, thereby causing elevation of the forward end of the tractor off of the ground, reducing the area of contact of the treads with the ground, and hence reducing traction power, until slippage of the treads on the ground occurs. At the outer side of each tread chain, tractor frame 4 includes a side rail 12 eX- tending horizontally from front t0 rear. However, as mentioned above, the tree pusher is ordinarily used with blade 14 elevated well above the ground, so that said pressure plane intersects the ground level well forwardly of sprocket 10. Used. Rockland TB Tree Booms are guaranteed against failure due to defective design, materials, or workmanship for a period of two years or 4,000 hours. The serrations 56 of the tooth prevent said tooth from slipping laterally out of engagement with the tree once pressure has been applied. The tree pusher attachment forming the subject matter of the present invention is indicated generally by the numeral 38, and includes a frame consisting of a pair of pusher beams 40 carried respectively by the push bars 18 of the bulldozer. These units put trees and brush on the ground in a hurry. 2, and. FIG. R. L. HOLLISTER, Assistant Examiner. With these objects in view,l as well as other objects which will appear in the course of the specification, reference will be had to the accompanying drawing, wherein: FIG.

Third, with the usual bulldozer mounting the pusher bars of the blade are often nearly horizontal, so that the strong reactive force in said bars tends to tilt the forward ends of the tractor treads upwardly from the ground, thereby reducing the traction of said treads against the ground by reducing the area of contact therebetween. As best shown in FIGS. beam forwardly of said blade and depending there-from, the rearward end surface of said block being inclined upwardly and forwardly whereby to hook -under the upper edge portion of the -forward face of said blade. The tractor shown is equipped with a generally standard bulldozer attachment including a blade 14 extending horizontally and transversely in front of the tractor, and being disposed in a generally vertical plane.

Optional high tensile steel Cutter Bar … 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. 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. Beams l40 act to prevent this, holding the brush down and causing it to be compacted into a rm mass rather than spilling over the blade. First, the edge of the bulldozer blade can in most assemblies be elevated perhaps only three or four feet above the ground, with the result that force must be applied to the tree relatively close to the ground. United States Patent O 3,377,724 TREE PUSHER ATTACHMENT FR BULLDOZERS William A. Jones, Jr., 710 S. Spring, Nevada, Mo. The forward face of said blade is concave, being curved about a horizontal axis, the lower edge thereof forming a cutting edge 16 for cutting in-to the ground when the bulldozer is used 4for earth moving and the like, and the upper edge portion thereof being inclined forwardly and upwardly to insure a forward roll or turn-over of earth once it has climbed up the entire height of the blade.

However, the usual bulldozer is subject to certain disadvantages in this particular usage. 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. New. CATERPILLAR D5G XL Dozer Stick Rake Tree Pusher DOZATT StickRake to suit Cat D5 Bulldozer, Wholesale price------ 12,500 GST . Third, since tooth 52 is at a higher elevation than blade 14 could ever attain, the reactive compressive load exerted on beams 4u has a larger downward component tending to hold the tractor treads 6 firmly against the ground for better traction.
