ABSTRACT:
A bowl scraper is configured for attachment to a rotatable mixing machine support such that forces exerted on the bowl scraper during scraping operations hold the bowl scraper in place. The bowl scraper includes an attachment arm including an upper arm portion and a lower arm portion, wherein the upper arm portion and the lower arm portion are formed by a bent elongated member. The upper arm portion includes an opening extending through the bent elongated member. The opening has a first portion and a second portion, the first portion of the opening being larger than the second portion of the opening. A scraper extends downward from the lower arm portion.
