Scraping tool systems

Abstract

A scraping tool for removing material from a bucket. The scraping tool has a blade which conforms to the curved sidewall of a bucket and is substantially flat so it can be inexpensively manufactured and efficiently stacked for shipping and storage.

Description

BACKGROUND

This invention relates to providing a system for improved removal of material from buckets. More particularly this invention relates to providing a system for removing material from a bucket using a specially configured scraping tool.
