The chute attachment is attached to a chute on cement truck at a receiving end so that cement might flow through the receiving end to an outlet end having a reduced size compared to the receiving end and into the desired place. A closure assembly is provided to close the chute attachment to thereby cut off the flow of cement, and minimize or avoid any spillage. The chute attachment has a frame which includes a circular assembly having large, middle and small circular members. The members are secured together at a common tangential point and a cover is secured to the frame.
