A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

A system, an apparatus and a method for uniformly applying UAN fertilizing liquid to soil on farmland for the purpose of increasing crop yields. The system has an UAN sprayer distribution rail applicator apparatus which may be pulled behind a tow vehicle or pushed by a sprayer or fertilizer applicator. The atmospheric tank contains UAN fertilizing liquid which passes from a pump, through a safety shut-off valve, and through a turbine style flow meter. A safety bypass line is provided upstream of the flow meter to relieve unsafe hydraulic pressure back through a pressure-sensitive valve in the event that multiple control valves close simultaneously. Flow through this bypass line also provides mixing of the UAN fertilizing liquid during cold weather. Upon exiting the flow meter, the UAN fluid enters the center of a distribution rail assembly. Spray nozzles with individual automatic shut-off valves are spaced across the distribution rail assembly.

An electric-powered bulk material dispersing system and method of use. The electric power is provided by a battery system with one or more electric motors to replace traditional internal combustion engines. The electric motor or motors are used to provide pressure to one or more pumps that may be used in conjunction with various tubes, hoses or related conduit and spray nozzles in order to disperse a bulk material such as seed, mulch, compost, chipped wood, grain, hay, fertilizer, herbicide, pesticide, plastic pellets, salt, sand or the like that has been combined or suspended within a fluent material. In one form, the bulk material dispersing system may be used as a bulk hydroseeder.

An automated steering system for an agricultural vehicle operating in a row crop field. The automated steering system includes a correction system having a controller and an alignment sensor. The alignment sensor is disposed between two adjacently spaced crop rows and generates output signals indicative of the alignment sensor's lateral position relative to the two adjacently spaced crop rows as the vehicle advances in the forward direction of travel. The controller receives the generated output signals from the alignment sensor and determines an offset distance of said alignment sensor from a centerline between the two adjacently spaced crop rows. The controller outputs a modified vehicle position signal corresponding to the latitude and longitude position received from said GPS receiver shifted by the offset distance. The vehicle's on board navigation controller causes the vehicles on-board steering control system to steer the vehicle based on the modified vehicle position signal.

A hydraulic spray nozzle, a hydroseeding system and a method of dispersing bulk material with a hydraulic spray nozzle. The hydraulic spray nozzle may further include one or more of an inlet, a diffuser cone, an expansion chamber, one or more interior surface vanes, a converging nozzle and an outlet that fluidly cooperate with one another in order to increase the dispersal distance of the bulk material as it exits the hydraulic spray nozzle. In one form, the hydraulic spray nozzle is incorporated into a hydroseeding system or other bulk material dispersing system in order to apply seeds, mulch, fertilizer or related bulk materials over large swaths of land.
