Bulldozers are large tracked machines with a front blade used for heavy grading, push-back, and site preparation. Available in sizes from 50 to 500+ horsepower. Blade widths typically range from 12 to 24 feet. Typical rental costs range from $200-$600 per day depending on size. Bulldozers excel at moving large volumes of material, pushing back material piles, and rough grading. Fuel consumption typically ranges from 10-30 gallons per hour depending on machine size and duty. These machines require experienced operators due to their weight (40,000-90,000+ pounds) and powerful blade force. Specialized attachments include rippers (for breaking hardpan), angle blades, and tilt blades. Common applications include site clearing, road construction, and landfill operations. Operator certification is recommended for safety and efficiency.
