1. An agricultural machine comprising:
one or more tires;
a detector to detect a low pressure state in which a tire pressure of the one or more tires is lower than a reference range or a high pressure state in which the tire pressure is higher than the reference range; and
a controller configured or programmed to control an operation of at least one of the agricultural machine and an additional agricultural machine to be linked to the agricultural machine; wherein
one of the agricultural machine and the additional agricultural machine is a work vehicle that is capable of self-driving, and the other of the agricultural machine and the additional agricultural machine is an implement to be linked to the work vehicle in use;
the controller is configured or programmed to cause, in response to detection of the low pressure state or the high pressure state, at least one of the agricultural machine and the additional agricultural machine to perform a specific operation that is different from an operation to be performed when the tire pressure is in the reference range;
the implement includes a sprayer to spray a chemical agent over a crop; and
the controller is configured or programmed to change, in response to the detection of the low pressure state or the high pressure state during self-driving of the work vehicle, a position and/or an attitude of the sprayer to prevent the sprayer from coming into contact with the crop.
