It is thought that the use or operation of the implement
will be readily apparent from a consideration of the fore
going. Brie?y, when it is desired to use the device with a
pulling stroke the blade assembly comprising the mem—
bers 27 and 32 is swung to the position shown in FIG
URES 1 and 2 of the drawing, in which position said
blade assembly extends at a forward and downward in
clination from the crosshead 12. When it is desired to
convert to a pushing operation the blade assembly is
swung through the intermediate position of FIGURE 3
50 of the drawing to the position shown in FIGURE 4 of
said drawing, in which position said blade assembly eX
tends at a rearward and downward inclination from the
crosshead 12. In both positions the blade assembly trails
through one end portion of the device, taken substantial
the crosshead 12 in the opreating stroke of the implement.
