WORKING MACHINE AND METHOD OF CONTROLLING WORKING MACHINE

A controller selectively executes a first mode and a second mode. In the second mode, a target tractive force of a machine is limited in comparison to the first mode. The controller weakens limitation of the target tractive force and determines the target tractive force when an acceleration of the machine during the second mode is less than a predetermined acceleration threshold. The controller determines a target transmission gear ratio in accordance with the target tractive force. The controller controls a transmission based on the target transmission gear ratio.
