Abstract:
A wheel loader includes a vehicle body, a work implement, a link mechanism and a control section. The work implement has a boom a work tool. The link mechanism is configured and arranged to change a relative angle of the work tool with respect to the boom when the boom is rotated upward, such that an amount of variation of an angle of the work tool with respect to a horizontal direction is less than an amount of variation of an angle of the work tool with respect to the horizontal direction when the boom is rotated upward while the work tool is at a fixed relative angle with respect to the boom. The control section is configured to execute an auto tilt control that causes the work tool to rotate upward when the boom is rotated upward within an angular range below the horizontal direction during excavation.
