Abstract

A working vehicle includes a linkage to attach/detach an attachment thereto/therefrom, a receiver to receive wireless signal(s) which are transmitted periodically from transmitter(s) in or on one or more of the attachments, which include respective piece(s) of identification information of the attachment(s), and which are compliant with a near field communication standard, and a controller configured or programmed to select a piece of identification information of the attachment attached to the linkage based on the piece(s) of identification information included in the wireless signal(s) received by the receiver and on received signal strength(s) of the wireless signal(s), and perform a predetermined process based on the selected piece of identification information. The controller is configured or programmed to correct the received signal strength(s) based on the piece(s) of identification information, and select the piece of identification information of the attachment attached to the linkage based on the corrected received signal strength(s).
