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. The blade is supported by a pair of push bars 18 disposed respectively at opposite sides thereof and extending rearwardly therefrom along the opposite sides of the tractor frame. 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. © 2012-2020 Rockland Manufacturing Company1-800-458-3773, © 2012-2020 Rockland Manufacturing Company. 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. Swing down support legs. The forward edge of the tooth plate eX- tends forwardly of beams 4i?, and is serrated as shown at 56 in FIG. The spacing of tooth 52 at a greater distance ahead of the tractor largely solves this difficulty.
Side-to-side swaying of the pusher attachment frame, consisting of beams 40, is prevented by a pair of upstanding angled clips 66 welded to the upper edge of blade 14, or to the reinforcing portion of said blade such as angle iron 62 which stiffens and reinforces the upper edge of said blade, respectively at the distal sides of said beams. There must of course be sufficient clearance between the clips and the beams, as shown in 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. 3 is a fragmentary sectional view taken on yline III- III of FIG. (c) means 'for preventing upward movement of each of said pusher beams relative to said blade, said means comprising a hook member consisting of a block afiixed to the lower side of said. Push bars 18 may be pivoted vertically on pivots 22, whereby to vary the elevation of blade 14 above the ground, by any suitable means, that shown consisting of a block-and-tackle hoist indicated generally at 30, the lower end of said hoist being connected at 32 to the rearward face of blade 14, and the upper end of said hoist being connected at 34 to a bracket 36 affixed to the forward end of tractor frame 4.

454,104 2 Claims. 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. United States Patent O 3,377,724 TREE PUSHER ATTACHMENT FR BULLDOZERS William A. Jones, Jr., 710 S. Spring, Nevada, Mo. 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. 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. Forward angle radiator guard. 2, to permit the beams to be moved forwardly over the blade enough to permit hooks 46 to engage said blade as previously described. 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.

The “V” design provides maximum shearing action while the tractor moves forward at a steady pace. Usually mounted in conjunction with a rake or a dozer blade.
These pins may be inserted after first engaging hooks 46 over blade 14, or alternatively the pusher attachment can be mounted by inserting pins 44 first, then, by manipulation of turnbuckles 24, first moving the upper edge of blade 14 rearwardly to allow hooks 46 to drop in front of the blade, then `moving the blade forwardly, to engage the undercut ends 4S of said hooks. ", CATERPILLAR D5G XL Dozer Stick Rake & Tree Pusher DOZATT. … The serrations 56 of the tooth prevent said tooth from slipping laterally out of engagement with the tree once pressure has been applied. First, tooth 52 can and does engage the tree trunk at a much higher elevation than blade 14 ever could, thereby providing a much better leverage and permitting the felling of larger trees with a tractor of any given power. 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. Consists of top quality high tensile and wear resistant materials Assembled top quality tradesmen.
