4.3. Cycle Time

Try these first

1. 1.

   What does cutting ratio measure in bulldozer performance?

   Hint

   Think about how power relates to cutting effectiveness.

2. 2.

   Name one benefit of a U blade?

   Hint

   Recall the shape of the blade and its effect.

3. 3.

   What is the cutting ratio?

   • Horsepower per meter of cutting edge
   • Horsepower per cubic meter
   • The weight of the blade

   Hint

   Focus on what defines the power of the blade.

4. 4.

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

   • True
   • False

   Hint

   Think about the dimensions and power concentration.

5. 5.

   A construction site requires both cutting hard soil and moving lighter soil materials. Propose a strategy using different blade types to maximize efficiency.

   Hint

   Consider the properties of each blade type before making your choice.

6. 6.

   Calculate the time efficiency difference between using a straight blade versus an angle blade on a job site with hard and uneven terrain.

   Hint

   Think about the actual job conditions that affect each blade's performance.
