This early 20th-century innovation of putting both a motor and track onto the previous versions of bulldozers paved the way for future upgrades to the dozer.
However, tractors with blades would not have this track added to them until 1921.
Tracked vehicles came into use to replace pack animals for driving tractors. A driver rode on a two-wheeled caisson attached by an arm to the blade. A massive, flat blade behind the draft animals scraped the land. These early bulldozers got their name from the pair of bulls that provided the power. In the late 19th century, railroad companies first used bulldozers to prepare the ground for rail lines. By using these tips and the right tools, you can learn to grade land correctly and efficiently and save time on building projects that require grading or spreading material.īulldozers use a blade to move earth, which can help with flattening land for roadways or construction sites. Mistakes made during land grading can set back jobs, costing the contractor and everyone on the construction team money.
