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. 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. 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. Price is per hour plus GST Plus a small cartage fee.

The operation of the attachment is believed obvious.

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. Such material of course accumulates to a large volume very rapidly, and then tends to spill rearwardly over the upper edge of blade 14. Another object is the provision of a tree-pusher attachment of the character described which is extremely simple and convenient to attach to or remove from the bulldozer, said attachment involving only the insertion of two pivot pins, and which may be elevated or lowered relative to a tree by the usual power apparatus of the tractor.
