Each of these attachments adds to the overall weight, and their impact on the bulldozer’s weight can be substantial when combined.
Blade Type
The type of blade fitted to a D6 bulldozer plays a significant role in determining its overall weight. The blade is the primary tool for earth-moving, and different blade configurations offer different levels of strength, size, and weight.
- Straight Blade (S-Blade): A straight blade is typically used for general pushing and grading tasks. It is more streamlined and tends to be lighter than other blade types, adding less weight to the bulldozer. Straight blades are ideal for tasks requiring precise grading or moving material over a flat surface, and their weight generally ranges from 2,000 lb (907 kg) to 4,000 lb (1,814 kg).
- U-Blade: The U-blade, often used for more demanding tasks such as pushing large amounts of material or handling loose soil, has a more substantial design. This blade is deeper and more curved, which allows it to carry heavier loads. Due to its larger size, a U-blade can weigh significantly more than a straight blade, often adding between 4,000 lb (1,814 kg) and 8,000 lb (3,629 kg) to the bulldozer’s weight. The U-blade provides better digging and lifting power, but this comes at the cost of increased weight.
- Combination Blade (SU-Blade): Some D6 models come with a combination of the S-blade and the U-blade, known as an SU-blade. This combination blade offers versatility for various tasks. Its weight falls between that of a straight blade and a U-blade, providing an optimal balance for operators who need both precision and power.
Undercarriage Configuration
The undercarriage of a D6 bulldozer is an essential component that influences its overall weight and performance. The undercarriage consists of the tracks, sprockets, rollers, and other parts that allow the bulldozer to move across rough and uneven terrain.

- Low Ground Pressure (LGP) Models: D6 bulldozers equipped with LGP undercarriages are specifically designed to handle soft, loose, or marshy ground. These models have wider tracks that distribute the weight of the machine over a larger surface area, reducing ground pressure. However, the wider tracks add more weight to the bulldozer, making it heavier than standard models. The LGP configuration helps the bulldozer maintain traction in challenging conditions while spreading the weight more evenly to prevent sinking or getting stuck.
- Standard Undercarriage: Standard D6 bulldozers with narrower tracks typically weigh less than their LGP counterparts. These bulldozers are designed for use on more solid ground where the risk of sinking is minimal. The standard undercarriage configuration is more suited for tasks such as grading and pushing on hard, compact surfaces.
- Track Length and Width: The length and width of the tracks also play a role in the overall weight. Longer tracks generally add more weight, but they also offer better stability and smoother operation over rough ground.
