Abstract: A water filtration system and method combining the porous, filtering medium of activated charcoal with anti-algae effects of barley straw. Ground activated charcoal and ground barley straw are compressed into filtration matrices. Compressed filtration matrices are configured to be housed within a mesh container and for placement within an open pond or water tank. The water filtration system and method filters contaminants and inhibits algae growth in the water, thus cleaning, filtering, and clarifying the water.

Abstract: A tillage with an auto-reset mechanism and system adapted for tripping when a tool encounters an obstacle in the field, and automatically resetting when the obstacle is cleared. The mechanism is adapted for mounting various ground-working tools, such as shank-mounted chisels, which typically operate slightly below the ground surface and are thus susceptible to damage from submerged obstacles, such as rocks, buried timber and tree roots.

Abstract: A transport lock joint is provided for an implement with a center section and wing sections adapted for stack folding to transport positions over the center section. The lock joint includes an insert element mounted on one of the wing sections and a retainer element mounted on the other wing section. With the implement in its stack-folded transport position, the insert element is received within the retainer element and the wing sections are mutually restrained against relative movement, particularly relative movement associated with the over-the-road travel. Unfolding the implement to a field working position disengages the lock joint by extracting the insert element from the retainer element.
