4.1. Blade Type

Try these first

1. 1.

   What is the cutting edge of a bulldozer blade?

   Hint

   Think about the part that makes contact with the ground.

2. 2.

   What does the load ratio measure?

   Hint

   It relates to the pushing ability of the blade.

3. 3.

   What is a cutting edge?

   • A part of the blade that can wear out
   • The entire blade of the bulldozer
   • The engine of the bulldozer

   Hint

   Recall the component that makes contact with the surface being pushed.

4. 4.

   True or False: A U blade typically has a higher cutting ratio than a straight blade.

   • True
   • False

   Hint

   Consider which blade is designed to cut through tougher materials.

5. 5.

   You need to move a large volume of loose, sandy soil across a job site. Which blade type would you choose and why?

   Hint

   Think about the soil type and how it interacts with different blades.

6. 6.

   Discuss how the performance metrics of cutting and load ratios would vary for different blade types when faced with dense clay soil.

   Hint

   Consider how density affects blade efficiency.
