Rakes are recommended if the tractor will be used for tree removal and stacking, in addition to pushing trees. 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.

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.

Used. 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. A pusher tooth 52 consisting of a heavy steel plate extends between plates 52, and is rigidly but removably secured thereto by a plurality of bolts 54.
Solid 450 grade high-tensile wear resistant alloy tynes.
Second, tooth 52 is spaced much farther in front of the tractor, and its treads, than blade 14 is or practically could be, so that there is considerable space between the tractor and the base of the tree during the felling operation. This invention relates to new and useful improvements in bulldozer equipment, and has as its principal object the provision` of an attachment for a bulldozer which particularly and especially adapts said bulldozer for use in pushing over trees. 1 and 2., pusher beams 40 extend substantially straight forwardly to a point approximately even with the front of tread chains 6, then converge forwardly toward each other, said beams resting at points intermediate their ends on the upper edge of blade 14, so as to be inclined upwardly and forwardly, and extending to a point spaced well forwardly of said blade. The structure as recited in claim 1 wherein said blade is connected to said push bars for adjustable pivotal movement about an axis parallel to the pivotal connection of said pusher beams to said push bars, whereby the upper edge portion of said blade may be moved into and out Iof engagement with said hook members.
A tree pusher attachment for use in connection with a tractor equipped with a bulldozer having a frame including a blade extending horizontally and laterally in front thereof, the upper edge portion of the forward face of said bulldozer blade being inclined upwa-rdly and forwardly, a pair of push bars attached to said blade respectively at opposite sides thereof and extending rearwardly therefrom along opposite sides of said tractor and pivoted at their rearward ends to said tractor for vertical movement, and power lmeans for pivoting said push bars vertically, said tree pusher attachment comprising: (a) an attachment -frame comprising a pair o f pusher 30 beams adapted to be pivoted respectively at their rearward ends to said push bars for vertical movement and to rest at points inter-mediate their ends on the transversely extending horizontal -upper edge of said bulldozer blade, so as to extend substantially forwardly and upwardly from said bulldozer blade, (b) a pusher tooth extending between and rigidly interconnecting the forward ends of said pusher beams, and.

Optional high tensile steel Cutter Bar available for installation at time of order. 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.
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. 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. Usually mounted in conjunction with a rake or a dozer blade. Bronze Member Optional high tensile steel Cutter Bar available for installation at ti.... Australian made 300-400hp Dozer Excellent design combining strength and efficiency. Dozer tree pusher (boom) Discussion in 'Dozers' started by wingnut, Apr 26, 2009. Said hook member is disposed forwardly of blade 14, and the rearward end thereof is undercut, as indicated at 48, whereby to engage beneath the upper edge portion of blade 14, and thereby to prevent any possibility of upward movement of beams 40 from the blade.
Fourth, the tree pusher attachment is extremely simple and convenient to attach to or remove from the bulldozer. While I have shown and described a specific embodiment of my invention, it will be readily apparent that many minor changes of structure and operation could be made without departing from the spirit of the invention as defined by the scope of the appended claims.
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.

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. The tough, center mounted splitter makes short work of large trees that cannot be sheared off in a single pass.
Multiply tractor horsepower by leverage so that large trees are quickly pushed over and root systems exposed for easy removal.

In this connection it will be seen that the bulldozer attachment of the tractor, and the tree pusher attachment, may be considered as a structural unit, pivoted to the tractor frame at 22, and pivotally connected to the tree at serrated edge of tooth 52, and that the reactive compressive load referred to above will be applied in this plane. Built for jungle-duty land clearing. These units put trees and brush on the ground in a hurry. This is important since when felling a tree by this method, the trunk itself 4generally does not break. When the attachment has been mounted on the bulldozer as shown, tooth 52 is moved to the desired elevation, as may be dictated by the size of the tree to be felled as well as by other considerations, by operation of hoist 30.
