Abstract: A monitoring system for an agricultural vehicle. The vehicle is provided with a video camera and an associated video monitor. The video monitor is located in a cab of the vehicle and the video camera is oriented facing the rear of the vehicle. When an agricultural implement is connected to the vehicle, the monitor may be used to view the implement without turning away from the direction of travel.

Abstract: An applicator for injecting anhydrous ammonia into the soil. The applicator includes a pulling vehicle and a tool bar which are releasably coupled to one another. The pulling vehicle carries a large anhydrous ammonia storage tank and is preferably provided with a pump to move anhydrous ammonia from the storage tank to the tool bar. Additionally, the pulling vehicle is provided with a plurality of large tires to reduce compaction to the soil. Because of the capacity of the anhydrous ammonia tank and the size of the pulling vehicle, anhydrous ammonia can be injected in to the soil at a very rapid rate.

Abstract: A vehicle for applying nitrogen to the soil. The vehicle includes a pulling vehicle having a massive towing capacity and a tool bar coupled to the pulling vehicle. A large anhydrous ammonia tank is secured to the pulling vehicle and a pump is secured between the tank and the tool bar to move anhydrous ammonia from the tank to the tool bar, where the anhydrous ammonia is injected into the soil. By pumping the anhydrous ammonia, the present invention can be used to apply anhydrous ammonia to the soil in temperatures which would otherwise be too cold to effectively apply anhydrous ammonia using only vapor pressure.
