Abstract: A system for applying pressurized anhydrous ammonia to soil. The system includes a tank for containing the pressurized anhydrous ammonia. An anhydrous ammonia meter is in fluid communication with the tank for dispersing controlled amounts of the anhydrous ammonia. A pressurization unit is also in fluid communication with the tank. The pressurization unit defines a pressurization chamber through which anhydrous ammonia from the tank is circulated. A heating system cooperates with the pressurization unit to heat the anhydrous ammonia within the pressurization chamber. The heated anhydrous ammonia is returned from the pressurization chamber to the tank. By adding the heated anhydrous ammonia to the tank, the pressure within the tank is stabilized or even slightly increased.

Abstract: An agricultural sprayer (10) comprises a mobile frame (12) supporting a spray system (90) in which the water and chemical concentrate are stored in separate tanks (92, 94, 96 and 98) for mixture in the desired ratio as needed responsive to travel of the sprayer so as to facilitate application at the proper rate. The frame (12) preferably comprises a main frame section (14) with outboard pairs of pivotal frame sections (16, 18) which are individually supported by adjustable gauge wheels (34, 54) movable between raised and lowered positions relative to the ground by actuator assemblies (60). The spray system (90) includes a water tank (92) and a plurality of chemical tanks (94, 96 and 98) connected through individual shut-off valves, adjustable, positive displacement pumps, and an electrostatic water treater, to a plurality of spray heads.

Abstract: An auxiliary water container mounted on an agricultural chemical tank by a pair of straps which encircle the chemical tank and overlies shoulders formed on the auxiliary housing. Ridges formed on the shoulders outwardly of each of the straps restrain the straps from accidental displacement from the shoulders and the auxiliary water container from its position on the chemical tank. The auxiliary water container is further provided with liquid dispensing apparatus which is easily accessible along both sides of the chemical tank if chemicals are accidentally spilled on an individual in the vicinity of the chemical tank.

Abstract: Improved apparatus for use in distributing anhydrous ammonia for agricultural applications, including a compact, convenient assembly combining in a single portable unit a flow meter, a control valve, a rotary fluid motor, an ammonia input, and means for mounting the assembly on any available application implement for connection to the ammonia source, the ammonia applicators, and the power fluid from a towing tractor.
