Starting principle of old bulldozers

The starting principle of old bulldozers mainly relies on gasoline engines to start large diesel engines. This starting method is different from the electric start or compression start used by modern bulldozers. Old bulldozers usually use wire ropes to assist in raising and lowering the bulldozer blade. This design was applied in 1931 when the first batch of 60 bulldozers with diesel engines were successfully launched. This starting method reflects the technical level and design characteristics of the bulldozers at that time.
