    Abstract: A dual gate control assembly for a spreader includes a rotary plate pivotable between fully open and fully closed positions with respect to openings formed in the hopper. A spreader gate is provided at the outermost openings of the hopper and rotary plate with each spreader gate being independently movable between fully opened and fully closed positions allowing for a plurality of variable operational modes affecting both material drop amount and spread direction.

    Abstract: An internal pump backpack sprayer system includes a first tank, a second tank and a pump unit. The first tank includes a tank housing for holding a fluid. The second tank is received within the first tank and receives a pressurized fluid. The pump unit has a cylinder housing with first and second inlets and first and second outlets, a piston within a cylinder and a pressure discharge assembly. When the piston moves in an up-stroke, fluid is drawn from the first tank through the first inlet while all or some pressurized fluid is discharged through the pressure discharge assembly with a remainder being discharged to the second tank through the second outlet. When the piston moves in a down-stroke, fluid is drawn from the first tank through the second inlet while pressurized fluid is discharged to the second tank through the first outlet.

    Abstract: A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

    Abstract: An external by-pass circuit for a positive displacement pump includes a flow diverter valve coupled to the pressure port of the pump. The flow diverter has an end coupled with a high flow output and another end coupled with a low flow output. The low flow end includes a by-pass arm coupled to and input flow fitting. The flow diverter valve further includes a ball valve to direct fluid to either the high flow or low flow output. The input flow fitting is coupled to the suction port of the pump at the one end and couples with a fluid source at the other end. The input flow fitting includes a flow control arm which includes a needle valve to selectively control flow within the flow control arm. The flow control arm also includes a by-pass fitting fluidly coupled with the by-pass arm of the flow diverter valve.

    Abstract: An applicator for introducing a fluid to a plant includes a first arm and a second arm pivotally connected to one another at one end. The other ends are spaced apart to receive the plant therein when the applicator is in a rest position and are driven together upon pivoting of the arms to place the applicator in an application position. A fluid injector is mounted on the first arm and includes an injector body and a diaphragm defining a plurality of channels. The diaphragm includes a pliable dome defining a reservoir to receive the fluid and a plurality of applicator nodes. A respective applicator node is positioned near a terminus of each channel. A driving member engages the pliable dome when the applicator is pivoted to the application position. The pliable dome is then compressed by the driving member to direct the fluid through the plurality of channels.
