ABSTRACT:
The loader bucket sieve apparatus is clamped between the jaws of the bucket of a bucket loader or the like, without tools or fasteners. Importantly, as the apparatus rests upon a given surface, the loader operator need only place the jaws of the bucket in the appropriate positions and then clamp the jaws together, reversing said procedure when wishing to disengage the apparatus. The apparatus may have straight supports or concave supports, depending upon need and bucket application. The sieves may extend beyond each side of the supports at each side of the apparatus in order to increase work surface beyond the bounds of the jaws. The sieves may be equidistantly spaced and may also be unequally spaced apart. Sieves may be disposed within all the holes or part of the holes of the supports.
