Abstract: A scent dispenser is provided to dispense liquid scent during a hunt for wild game. The inventive scent dispenser uses age old scientific and natural phenomena to enhance the speed of the wind. The provided dispenser uses a venturi wind channel to accomplish a wind speed increase. Supported at its center of gravity from above or below, allowing rotation, the funnel shaped wind channel is continuously aligned with the wind direction by a wind vane. Liquid scent is introduced in the constricted section of the venturi wind channel where the wind velocity is increased. This increased wind speed, and continuous alignment to wind direction, enhances the vaporization of liquid scents that attract wild game, and that mask the scent of a hunter from the wild game's keen sense of smell.

Abstract: A track assembly for a mobile tower of an irrigation system includes: a mounting bracket configured to be attached to the mobile tower; a gearbox assembly and rotatable drive wheel hub attached to the mounting bracket; a drive wheel attached to the drive hub; rotatable tension wheel hub attached to the mounting bracket and spaced from the drive hub; a tension wheel attached to the tension wheel hub; and a track trained over the drive wheel and the tension wheel and driven by the drive wheel to propel the mobile tower.

Abstract: Injection apparatus for automatically applying pest control concentrates and fertilizers into an existing underground irrigation system. Apparatus uses an electronic control system programmed to activate one or more injection pumps and to also operate the zonal flow control solenoids contained in an existing underground or other type of irrigation system. Apparatus includes a single or plurality of storage reservoirs for storing one or more additives with piping to deliver these additives to the existing irrigation system.
