A bulldozer blade is a heavy metal plate on the front of a bulldozer that is used to push objects, such as sand, soil, debris (solid waste), sometimes snow, etc. There are different types of bulldozers to choose from depending on your specific project. The type of land you are working on, the type of project you are working on, and other criteria are key factors to consider when choosing a bulldozer. Choosing the right machine is critical to the efficiency and safety of your project.

Flat curved blade
This is the shortest type of blade and has no side bends or side fins. S-blades are often equipped with a hydraulic cylinder, which allows you to sleep more powerfully. Due to the correct shape, this type of knives does not allow you to carry heavy loads. It is best suited for work such as grading, trenching and stripping.
Angled knife
This type of blade is connected to the middle of the bulldozer panel. Its location is useful for moving debris sideways, as it has an angle of about 30 degrees to the left or right. Therefore, the angle knife is a double-edged blade. Be aware that this blade can spill because it has no side fins. It is an excellent choice for projects involving soft to medium-density soil, snow and gravel. The best jobs for bevel knives include gouging, shaping, stripping, and gouging.
Semi-U (S-U) blade
This blade combines the features of an S-blade and a U-blade, giving it greater penetration and overall versatility. It is narrower, less curved and has smaller side fins than a regular U-blade. This design makes it ideal for pushing soil over long distances. This blade is attached to the lower back of the blade using angle stabilizers and one or two hydraulic cylinders. It is better for pushing soft and medium density sand and soil. The best tasks for an SU blade include crowning, moving heavy material, prying and throwing.
The cultivator is purchased on an optional basis.
