Abstract
A load control unit for a bulldozer, comprising an actual tractive force detector for detecting the actual tractive force of a vehicle body; target tractive force setting switch for setting a target tractive force for an automatic blade control mode in dozing operation; and 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 the target tractive force set by the target tractive force setting switch when digging is started with the automatic blade control mode in dozing operation, the actual tractive force gradually comes closer to the target tractive force.
