Abstract
A dozing system for a bulldozer, comprising an actual tractive force detector for detecting an actual tractive force of a vehicle body; a target tractive force setting device for setting a target tractive force for a vehicle body; a tractive force deviation calculator for calculating the deviation between the actual tractive force detected by the actual tractive force detector and the target tractive force set by the target tractive force setting device; and a comparison control unit for controlling a blade to be lifted or lowered such that the absolute value of the deviation is increased, when at least the absolute value of the deviation is less than a preset value and tile actual tractive force is approaching the target tractive force.
