Abstract
A traction force control section of a wheel loader reduces maximum traction force to below the maximum traction force with traction force control in an off state when the traction force control is in an on state. The traction force control section increases the maximum traction force when determination conditions are satisfied with the traction force control in the on state. The determination conditions include that the work situation is digging, that the operation amount of the acceleration operation member is the predetermined operation threshold or more, and that a boom angle is the predetermined angle threshold or more.
