A spraying support system for a working machine, includes: a support device including a plan creator portion to create a spraying plan representing a relation between field information relating to a field to which spray substance is sprayed and spraying information including spraying amount of the spray substance; a plan obtainer device provided to a working machine having a sprayer device to spray the spray substance and configured to obtain the spraying plan created by the plan creator portion; and a spraying controller device to control a sprayer portion of the sprayer device based on the spraying information of the spraying plan obtained by the plan obtainer device.

A generator unit to be attached to a traveling vehicle that has a prime mover and a PTO shaft to transmit power from the prime mover, includes: a generator; an input shaft having: a first connector portion configured to be connected to the PTO shaft; and a second connector portion configured to be connected to a working device to be connected to the traveling vehicle; a transmitter mechanism to transmit, to the generator, power supplied from the PTO shaft, the power being inputted from the first connector portion to the input shaft; and an attachment frame having: an attachment portion to which the generator, the input shaft, and the transmitter mechanism are attached; and a mounting portion configured to be mounted to the traveling vehicle.

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 broadcast spreader broadly comprising a frame, a hopper, an impeller, a set of wheels, and an electric hub motor. The hopper is supported by the frame and configured to hold a particulate material. The impeller is rotatably connected below the hopper and is configured to receive the particulate material from the hopper and spread the particulate material over a surface. The wheels are rotatably connected to the frame for traversing the surface. The electric hub motor is at least partially positioned in one of the wheels and configured to drivably engage the one of the wheels to propel the hopper along the surface.

An attachment structure of a generator and a working machine including a transmission case; and a PTO shaft protruding from the transmission case, includes a structure body attached to a side of the transmission case from which the PTO shaft protrudes, and includes the generator attached to the structure body.

An apparatus for broadcasting particulate or granular material over a ground surface involves a variable speed spinner and a material conveyor. The spinner is positioned generally horizontally below a discharge end of a material conveyor. The spinner has a disk having a generally radially disposed fin fixed to an upper side of the disk and radiating outwardly from a center of the disk. The spinner is positioned to receive material from the material conveyor at a location about half way along a length of the fin. In a method broadcasting particulate or granular material over a ground surface, the spinner is preferably rotated at a speed of 900-1000 rpm. The apparatus and method provide for distribution of material over greater distances and can do so without pulverizing the material, creating a uniform pattern of distribution over a 50% wider swath.

A material spreader assembly for the broadcast spreading of particulate material from the trailer hitch of a vehicle. A hopper for storing the particulate material is supported by a frame having a trailer hitch coupler for connection to the vehicle. A spreader including a spinner driven by an electric motor receives and disperses the particulate material. A control circuit receives electric current from the vehicle via a plug interface and a wiring harness and controls the operation of the spreader. A remote communicates user commands to the control circuit. The control circuit includes a motor control processor that controls a motor power relay and a motor driver to gradually ramp up the current supplied to the spreader for start up the spreader while preventing a high transient current draw spike. Component feedback sensors enable the motor control processor to provide an emergency shut off feature and warning signals.

An agitation unit for use in a lawn spreader and other dispensing equipment, and oscillating agitation systems therefor comprising such an agitation unit. The agitation unit includes a hub, an arm extending from the hub, and an extension on the arm configured to project downwardly to an extent relative to the arm and the hub to protrude into, but not through, the outlet passageway of the hopper.

A working device connected to a traveling vehicle having a prime mover and configured to perform an agricultural work, includes: a working portion to perform an agricultural work; an electric motor to be driven by electric power; a power transmission mechanism to which power generated by the electric motor is inputted, configured to transmit the power to the working portion; a regeneration resistor to consume a regenerative power generated in the electric motor; a switch portion to switch, between a connecting state and a shut-off state, a state established between the electric motor and the regeneration resistor; and a controller portion to control driving of the electric motor and switching of the switch portion.

A working device to be connected to a traveling vehicle having a prime mover, the working device being configured to perform an agricultural work, includes a working portion to rotate to perform an agricultural work, an electric motor to be driven by electric power, a power transmission mechanism to which power generated by the electric motor is inputted, configured to transmit the power to the working portion; and a regeneration resistor to consume a regenerative power generated in the electric motor, the regeneration resistor being arranged at a position to be cooled by wind generated by rotation of the working portion.
