Try these first

1. 1.

   What is a cutting ratio?

   Hint

   Think about how power is related to blade size.

2. 2.

   Name one type of bulldozer blade.

   Hint

   What type do you remember that can be used for pushing?

3. 3.

   What factor does the cutting ratio primarily depend on?

   • Blade color
   • Size of the cutting edge
   • Blade height

   Hint

   Think about why smaller blades are strong.

4. 4.

   True or False: A straight blade cannot be angled.

5. 5.

   A construction site requires moving both dense and loose materials. Which bulldozer blades would you choose and why?

   Hint

   Consider the characteristics of each blade type.

6. 6.

   Calculate the cutting ratio if a bulldozer's cutting edge has a length of 2 meters and provides 200 horsepower. What does this imply for performance?

   Hint

   Think about how power is distributed along the edge.
