ABSTRACT:
A dozing control unit for a bulldozer, comprising an actual tractive force detector for detecting the actual tractive force of a vehicle body; a driving mode selector button capable of switching a manual operation mode to an automatic driving mode in dozing operation; and a blade controller for controlling a blade to be lifted or lowered such that if there is a difference between the actual tractive force detected by the actual tractive force detector and a target tractive force set for the automatic driving mode when the manual operation mode is switched to the automatic driving mode by the driving mode selector button, the actual tractive force gradually comes closer to the target tractive force.
