Abstract: A brush rake for attachment to an excavator arm equipped with a bucket and a thumb having inner and outer pairs of teeth. The brush rake has a parallel array of rake teeth attached to a rake bar, and a mounting plate having one end thereof attached to the rake bar. An opposite end of the mounting plate is adapted to overlie the body of the thumb and to be received between the outer pair of teeth of the thumb. A parallel pair of apertured ears attached to the rake bar is so disposed thereon that when the rake bar is placed adjacent and transversely with respect to the teeth of the thumb, the ears lie adjacent and on opposite sides of the inner teeth of the thumb. Mounting holes are provided in the mounting plate and matching holes are bored through the body of the thumb. The brush rake is attached to the thumb by inserting pins through the ears and through holes bored through the inner teeth of the thumb, and by inserting mounting bolts through the mounting holes and matching holes in the thumb.
