Abstract
A tractive force control part of a wheel loader is configured to perform a tractive force control to reduce a maximum tractive force. The tractive force control part is further configured to reduce the maximum tractive force when determination conditions including, while a working implement is performing excavation operation, that the working implement is in a raising hydraulic stall condition and that a drive circuit pressure is greater than or equal to a predetermined hydraulic pressure threshold are satisfied during the tractive force control.
