Abstract: A device and related system is disclosed for detachably mounting to the teeth of a wheel rake to support each individual tooth preventing premature tooth breakage. The device and system for mitigating stress on an individual wheel rake tooth includes a plurality of individual supports detachably mounted to two or more wheel rake teeth. The individual supports are detachably coupled to two adjacent individual supports via elongated openings at each end of the individual support. When detachably mounted to the wheel rake teeth at a radius inside the tip of the teeth, the supports act to distribute the stress on an individual wheel rake tooth among adjacent wheel rake teeth as the tooth impacts an object.

Abstract: A system described herein that provides for the opening, emptying and rinsing of the interior of a chemical container. The present system allows an operator to destructively perforate the bottom of a container, empty its contents into a vessel, rinse its interior and collect the drained chemical and rinse water in a suitable receptacle, such as a sprayer tank. This system provides for maximum efficiency, and the total use of the chemical within the container, as well as a safe means for rinsing a container prior to disposal. The system provides for a minimal contact of the contents of the container by the operator. The cutting arrangement includes a plurality of elongate blades inclined upwardly to an apex and a plurality of intervening bars for opening the slit base of the container. The cutting arrangement is provided in a vessel with a transportation duct and venturi at the bottom for carrying the contents in mixed condition away from the vessel.
