A chest-mounted spreader system includes a hopper for receiving particulate material and a base assembly mounted to the hopper. The base assembly has a base unit having a base plate and rotatable shaft. An electric motor is coupled to the shaft to drive rotation of the shaft. An impeller is mounted on the shaft proximate the base plate. A shroud has a partial sidewall affixed to the base plate thereby defining an impeller cavity. The impeller cavity includes a discharge opening opposite the partial sidewall and the impeller is received within the impeller cavity. A shroud opening is in fluid communication with the hopper so that particulate matter passes from the hopper to the impeller. The electric motor is powered to rotate the shaft and the impeller to disperse the particulate matter through the discharge opening.

A work management system includes a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine, an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator, a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion, and a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion.

A working machine includes: a first generator having: a rotor to be rotated by power from a PTO shaft; a rotor coil provided to the rotor; and a stator coil to generate electricity when magnetizing current is applied to the rotor coil; a working device to be operated by the electricity generated by the first generator; and a converter device to convert surplus electricity not consumed by the working device into the magnetizing current to be applied to the rotor coil.

A broadcast spreader, components thereof, and associated methods. The broadcast spreader includes a hopper, a spinner, a motor for turning the spinner, and a material feeder configured to feed granular material from the hopper to the spinner. The broadcast spreader includes a material feeder adjustment actuator, a spinner speed control actuator, and a motor on/off actuator. A harness wearable by a person is configured to carry the broadcast spreader. A kit of interchangeable battery adaptors enables use of different brands or models of batteries.

Self-propelled outdoor tool bases and assemblies are provided. A self-propelled outdoor tool assembly includes one or more tools and a drive system. A tool may be a transportation tool such as a spreader hopper. An assembly may include a base, and the tool may be removably connectable to the base. The assembly may include a toolless connection between the tool and the base.

A dispenser assembly for a mower that selectively dispenses liquid or particulates onto the ground is provided. The dispenser has a hopper with an inner receptacle, an attachment to the mower, and a particulate outlet at the bottom of the receptacle. The dispenser also has a tank that removably nests within the receptacle and a particulate distributor in communication with the outlet. The particulate distributor has an agitator within the receptacle near the outlet, the agitator directing particulates toward the outlet, and a spreader that distributes the particulates from the outlet onto the ground surface. The dispenser also has a fluid distributor carried by the mower that has a fluid passage releasably connected to the fluid outlet of the tank and a fluid manifold connected to the fluid passage. Fluid is pumped through the fluid passage to a fluid manifold, which distributes the fluid onto the ground.

A metering system and method of operating fertilizer distribution equipment, such as a spreader-sprayer, is described that includes monitoring revolution data for opposing left and right wheels with left and right sensors. A controller controls an actuator's operation to operably regulate the output of a liquid and/or solid fertilizer product. The fertilizer output is based at least in part on the revolution data and a fertilizer unit-per-area input.

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 working machine includes: a first generator having: a rotor to be rotated by power from a PTO shaft; a rotor coil provided to the rotor; and a stator coil to generate electricity when magnetizing current is applied to the rotor coil; a working device to be operated by the electricity generated by the first generator; and a converter device to convert surplus electricity not consumed by the working device into the magnetizing current to be applied to the rotor coil.

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.
