Abstract: A bucket clamp assembly receives and supports a five gallon bucket securely in place while the user mixes slurry-like products. The bucket is preferably inserted into the clamp assembly on the ground. The user places the bucket on a base plate between a fixed front support and an opposing hinged rear support and firmly against the hinged rear support, thereby raising a lever arm operating the hinged support to an open position. The user then presses her or his right foot firmly down on the exposed upper surface of the base plate and places the left foot across the lever arm. The clamp is thereby securely pressed to the ground using the worker's body weight. Further pressing the left foot down across the lever arm also forces the hinged rear clamp support surface to swing distally or forwardly, thereby firmly squeezing the sides of the bucket against the opposing, fixed clamp support, securing the bucket in place for safe and efficient mixing.
