  • Publication number: 20240428149
    Abstract: A lawn management assistance system 1 includes a communicator 32 and a processor 31. The communicator 32 receives positional information of a lawn mower 10 detected by a position sensor 16 installed at the lawn mower 10 and receives condition information of a lawn detected by a condition sensor 17 installed at the lawn mower 10. The processor 31 analyzes the condition information per piece of the positional information based on information received by the communicator 32 and generates and outputs improvement information indicating a method for improvement of condition of the lawn per piece of the positional information.

  • Publication number: 20240423122
    Abstract: A lawn mower 10 of the present embodiment travels on a lawn and cuts grass. The lawn mower 10 includes a drive source 12 and a controller 21. The drive source 12 generates power for the lawn mower 10 to travel. The controller 21 receives height at each position of the lawn from a sensor that detects the height at each position of the lawn or from a memory (a storage of the controller 21, a laptop PC 40, or a server) that stores the height at each position of the lawn and controls the drive source 12 based on a height change in the lawn in front in a travel direction to change a travel speed.
