What is claimed is: 1. A removable attachment for mounting to a loader bucket having a bottom wall, side walls and an upright rear wall, the bucket being moved under power to engage and receive materials, the attachment comprising a removable debris guard, including a debris guard frame having spaced apart side legs having lower ends, and a top member joining the side legs, a cross member between the side legs spaced downwardly from the top member and above the lower ends, a mesh screen covering a space formed between the top member and the cross member and secured to the debris guard frame and the cross member, the cross member having a hook adapted to go over a top edge of an upright rear wall of the loader bucket to prevent forward movement of the debris guard frame relative to the upright rear wall, and having a portion which engages parts of the upright rear wall to prevent rearward movement relative to the upright rear wall, to retain the debris guard inclined forwardly from and extending upwardly from the upright rear wall, the side legs extending beyond the cross member in a direction away from the top member and the lower ends of the side legs having attachment brackets for removably attaching to a forward side of the upright rear wall. 2. The attachment of claim 1 wherein the mesh screen has openings of at least 1 inch in major dimension, and is made of rods formed with mutually perpendicular lengths. 3. The attachment of claim 1 wherein said cross member is provided with side gussets for securing the cross member to the debris guard frame. 4. A debris guard for removable attachment to an upright wall of an earth working implement, the upright wall being supported on a prime mover, said debris guard comprising a frame having a top cross member, and side legs, lower ends of the side legs having attachment brackets for removably attaching to the upright wall on a forward side thereof, a mesh screen supported on the frame and extending between the side legs and below the top cross member, and a cross plate secured to and extending between the side legs, and supporting a lower side of the mesh screen, the cross plate having at least one hook for fitting over an upper edge of the upright wall when the frame is mounted on a forward side of the upright wall and the cross plate having portions which engage a forward side portion of the upright wall, whereby the at least one hook prevents forward movement of the debris guard frame and the cross plate portions prevent rearward movement of the debris guard frame when placed on an upright wall of the earth working implement. 5. The debris guard of claim 4, wherein the at least one hook is positioned so that when the debris guard is in place on the upright wall, the at least one hook is to a lateral side of a step supported on such upright wall. 6. The debris guard of claim 4, wherein the upright wall is a rear wall of a loader bucket and wherein there are two spaced apart step members on an upper rail of the rear wall of a bucket on which the debris guard is installed, and wherein the cross plate has three hooks, a first center hook adapted to be positioned between the step members, and a pair of end hooks adapted to be positioned on sides of the two step members when the debris guard is in position on the rear wall, the portions of the cross plate comprising edge portions between the hooks positioned to engage the step members to prevent rearward movement of the debris guard frame. 7. A debris guard for a loader bucket back wall comprising a debris guard frame having spaced apart side legs, and a top member joining the side legs, a cross member between the legs spaced downwardly from the top member, the cross member extending outwardly from the debris guard frame and having at least one flange to form a hook for hooking over a top edge of the bucket back wall and having a portion that engages a portion of the bucket back wall to prevent movement of the debris guard frame relative to the bucket back wall, the cross member spacing the debris guard frame forwardly from the top edge with the side legs on a forward side of the bucket back wall, a mesh screen secured to the debris guard frame and covering a space formed between the top member and the cross member, the side legs extending beyond the cross member in a direction away from the top member and having attachment brackets at ends thereof for engaging a forward side of the bucket back wall below the cross member, and wherein the top member of the debris guard frame is positioned forwardly of the bucket back wall of a bucket on which the debris guard is mounted, with the attachment brackets engaging a forward side of such bucket back wall. 8. The debris guard of claim 7, wherein the mesh screen has square openings ranging between 1 inch and 1.5 inches in dimension and is made of mutually perpendicular rods ranging between 3/16 and 5/16 inches in diameter. 9. The debris guard of claim 7, wherein the bucket back wall of a bucket on which the debris guard is installed has a step on a top edge thereof, the hook being located to be laterally of the step to permit access to use the step. 10. The debris guard of claim 7, further characterized by the attachment brackets defining a plane, and the side legs being angled such that the top member is spaced from the plane so the mesh screen angles away from the plane.
