ABSTRACT OF THE DISCLOSURE The invention comprises a cutting attachment for a trencher wherein the trencher has a pivotally mounted trencher arm with a drive sprocket gear for driving an endless chain and with a socket mounting at the outer end of the arm for mounting an outer sprocket for connecting a endless chain between the sprockets to drive the outer sprocket. The cutting attachment comprises a yoke having three legs with a shaft rotatably mounted between two of the legs and a outer sprocket fixed thereon and therebetween. A cutting blade is fixed to said shaft to be rotated with said shaft. A housing is provided to enclose a portion of the blade and is fixed to the yoke. The third leg of the yoke is mounted in the socket of the trencher arm whereby the trencher may power the drive sprocket to thereby rotate the outer sprocket through the endless chain and the outer sprocket may rotate the cutting blade, so that the arm may be pivoted down to lower the cutting blade to cut objects near the ground in a downward path.
