See full text

An automatic transmission system for a bulldozer includes an automatic speed stage shifting section that switches among speed stages depending on a vehicle speed, a speed stage maintaining section that maintains a currently selected speed stage until a predetermined speed stage shifting disobedient time elapses after completion of a speed stage shifting while disobeying a switching instruction from the automatic speed stage shifting section, a load detecting section that detects a vehicle load, and a control restricting section that restricts a control processing of the maintaining section for causing it to obey the shifting section's instruction when the vehicle load is a predetermined load or greater even before the disobedient time elapses.
