Patent ID: 8831797

Claim:
A wheel loader comprising: a vehicle body; a work implement having a boom attached rotatably in an up and down direction to the vehicle body, and a work tool attached rotatably in the up and down direction to a distal end of the boom; a link mechanism 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; a control section 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; and a traction parameter detector configured and arranged to detect a value of a traction parameter indicative of a magnitude of traction of the wheel loader towards a direction of forward advance, wherein the control section is configured to determine whether to execute the auto tilt control based on whether the traction parameter is equal to or greater than a predetermined value.
