Abstract
A wheel loader includes a boom, a forward clutch, and a controller configured to control hydraulic pressure of hydraulic oil supplied to the forward clutch. The controller performs clutch hydraulic pressure control for bringing the forward clutch into a semi-engagement state by controlling the hydraulic pressure of the hydraulic oil supplied to the forward clutch on condition that the wheel loader advances while raising the boom in at least a loaded state.
