Abstract
A material handling element or bucket is formed from two sidewalls and a backwall. The backwall has one or more apertures postioned in such a manner that the operator manipulating the bucket can see a portion of the leading edge of the bucket. In one embodiment, the apertures are positioned in such a manner that the leading edge can be viewed directly or in combination with one or more mirrors. In another embodiment, the apertures are positioned in such a manner so that the operator can sight one or more of the sidewalls of the bucket using those sidewalls as a guide for positioning the leading edge of the bucket.
