An apparatus for emptying a container including a body unit, a container platform, a cutting blade, and a hold-down assembly. The body unit at least partially defines a chamber, and the container platform is configured to support a container. The cutting blade is movable between a retracted position and an extended position. The cutting blade is located within the chamber when in the extended position. The cutting blade is configured to puncture a container positioned on the container platform as the cutting blade goes from the retracted position to the extended position. The hold-down assembly is configured to secure a container positioned on the container platform. The hold-down assembly is oriented such that a bracket and a shaft of the hold-down assembly are fixed relative to the body unit when an adjustable strut of the hold-down assembly is in a locked strut configuration.
