1. What is the primary function of a bulldozer on a construction site?
To push and move large amounts of soil, sand, rubble, or other
materials
Bulldozers are designed for earthmoving by using their powerful
blade to push materials efficiently over short distances.
2. What is the term for the large metal plate at the front of a bulldozer
used to push material?
Blade
The blade is the key working component of a bulldozer, allowing it to
move material.
,3. What is the purpose of a ripper attachment on a bulldozer?
To break up hard ground or rock
Rippers are used to loosen compacted soil, rock, or asphalt to make it
easier to move.
4. When operating on a slope, how should a bulldozer be driven for
maximum stability?
Straight up and down the slope, not sideways
Driving across a slope increases the risk of tipping; straight
movement maintains stability.
5. What is the most common type of bulldozer blade for general use?
Straight blade (S-blade)
An S-blade is short, with no side wings, making it suitable for fine
grading and short pushes.
6. What is the advantage of a U-blade over an S-blade?
It can carry more material due to its curved shape and side wings
The U-blade’s design traps material, allowing for larger loads per
push.
7. What does the term "track frame" refer to on a bulldozer?
The structure that supports and guides the tracks
The track frame holds the track assembly in place and allows
movement over rough terrain.
,8. Why are tracked bulldozers preferred over wheeled bulldozers in soft
ground?
Tracks distribute weight over a larger area, reducing ground pressure
Lower ground pressure prevents the machine from sinking into soft
soil.
9. What is the purpose of the operator’s pre-start inspection?
To ensure the bulldozer is in safe and proper working condition
before use
Regular inspections help prevent mechanical failure and accidents.
10. What should be checked in the engine compartment before
starting the bulldozer?
Oil level, coolant level, and fuel level
These checks prevent damage to the engine and ensure smooth
operation.
11. What is the safest way to mount and dismount a bulldozer?
Using three points of contact
Three points of contact reduce the risk of slips and falls.
12. What does the term "counterweight" refer to in bulldozer
operation?
A weight added to balance the machine during heavy lifting or
pushing
Counterweights improve stability and prevent tipping.
, 13. What type of fuel do most large bulldozers use?
Diesel
Diesel engines provide the high torque necessary for heavy pushing
tasks.
14. Why is it dangerous to exceed the bulldozer’s rated operating
capacity?
It can cause mechanical failure and loss of control
Overloading strains the engine, transmission, and structural
components.
15. What is the correct procedure for refueling a bulldozer?
Shut off the engine, ground the fuel nozzle, and avoid open flames
Following safe refueling procedures prevents fires and explosions.
16. Why is idling a bulldozer for long periods discouraged?
It wastes fuel and increases engine wear
Excessive idling leads to carbon buildup and reduces engine life.
17. When pushing material, what technique helps prevent blade
spillover?
Feathering the blade and making multiple passes
This controls the load and keeps material from falling off the sides.
18. What does "slot dozing" refer to?
Pushing material within a confined trench or slot for efficiency
