A spreader for broadcasting granular or particulate material over a surface includes a dual rotor configuration, a material deflection system, and a portable electronic device holder. The material deflection system includes components for deflecting material broadcasted by each of the rotors. The spreader includes a walking speed indicator to inform the user whether the current speed is too fast, too slow, or within an acceptable reference range.

A pull behind orchard fertilizing device includes a hopper, a main frame, a wheel assembly, a material discharging assembly, a gear box, and a spreader. The hopper is mounted onto the main frame. The wheel assembly is rotatably mounted to the main frame. The material discharging assembly is integrated into the hopper so that the fertilizer that is stored within the hopper can be discharged into the spreader. The spreader is terminally mounted to the main frame and positioned below the hopper. The gear box is mounted to the main frame so that the wheel assembly can be operatively coupled with the material discharging assembly and the spreader through the main gear box, wherein discharged fertilizer from the hopper is dropped into the orchard field through the operation the spreader.

Methods, apparatus, systems and articles of manufacture are disclosed for efficient material application. An example landscape treatment apparatus includes a main carrier tank to store a solvent, a concentrate tank to store a solute, and a first mix tank to receive the solvent and the solute as a first mixture. The example apparatus further includes a second mix tank to receive the solvent and the solute as a second mixture, where the first mix tank is to receive the solvent and the solute in alternation with the second mix tank receiving the solvent and the solute. The example apparatus also includes a boom to apply the first mixture and the second mixture to a landscape via a plurality of nozzles, where the boom is to apply the first mixture and the second mixture in alternation.

An agricultural aircraft for spreading granular fertilizer and a spreading method thereof. The agricultural aircraft includes an aircraft body, a power system, and a spreading device, where the spreading device is located at a front part of the aircraft body, and the aircraft body is also provided at the front thereof with a wind direction sensor and a wind speed sensor communicatively connected a controller; the spreading device includes a box body, a throwing disc, and a tray connected to the box body, where a left baffle plate and a right baffle plate with controllable opening angles are disposed on the tray; an upper part of the box body is a material box for storing granular fertilizer, a cavity for accommodating the tray and the throwing disc is disposed on one side of the box body.

An agitating system includes an agitator disposed within a sub-hopper of the agitating system. The agitator is configured to promote movement of the particulate material through the sub-hopper. The agitating system also includes a deflector assembly configured to movably couple to a bracket at a position laterally offset from a center axis of the agitator. The deflector assembly includes a deflector that establishes a space between the deflector and the agitator, and the deflector is configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper.

A spreader device includes a container to contain spread substance, a first spreader portion having a first rotor to spray the spread substance contained in the container, a second spreader portion having a second rotor to spray the spread substance contained in the container, a first driver source to drive the first rotor, a first shaft to transmit a driving force outputted from the first driver source, a second shaft to transmit a driving force outputted from a second driver source different from the first driver source, and a selection transmitter portion to selectively transmit the driving force form the first shaft and the driving force from the second shaft to the first rotor or the second rotor.
