Abstract: A quick acting coupler for a cultivator attachment, such as a cultivator fender, shield, or the like, in which the attachment is carried by a mounting frame with the latter being securable to the tool or cultivator bar of a cultivator implement for coupling of the attachment to the cultivator at a desired location on the cultivator. The coupler includes a hitch member for each attachment, each hitch member being securable to the tool bar of the cultivator at a desired position therealong. The mounting frame is connected to the hitch member by inserting one or more headed pins carried by the mounting frame into corresponding elongate vertical slots in the hitch member. The vertical slots each have an enlarged portion at their upper ends so as to receive the head of a respective headed pin and a narrower lower portion so as to receive the shank of the headed pin.

Abstract: A fluid or liquid powered pump system useful for injecting a liquid additive into a main stream of liquid flowing through the pump with the additive being pumped into the main liquid stream by movement of the liquid through the pump. The system has a pump body through which the main stream of liquid flows and in which the additive is injected into the liquid stream. The system further includes an unvented additive tank or bottle connected to the pump body by means of a single line.
