1. Which component is primarily responsible for transferring power
from the engine to the transmission in a tractor?
a) Clutch
b) Flywheel
c) Differential
d) Axle
The flywheel stores rotational energy and helps transmit power
smoothly from the engine to the transmission system.
2. What type of fuel is most commonly used in modern agricultural
diesel engines?
a) Gasoline
b) Diesel
c) Biodiesel only
d) Propane
Diesel engines are standard in agricultural machinery due to their
higher torque and fuel efficiency.
3. Which hydraulic system component controls the direction of fluid
flow?
a) Pump
b) Cylinder
, c) Directional control valve
d) Reservoir
Directional control valves regulate the path of hydraulic fluid,
controlling actuator movement.
4. A common cause of overheating in a tractor engine is:
a) Low tire pressure
b) Coolant system failure
c) Faulty air filter
d) Transmission oil leak
The cooling system removes excess heat; failure can lead to engine
overheating.
5. Which gear arrangement increases torque while reducing speed in
agricultural equipment?
a) Spur gear
b) Helical gear
c) Planetary gear
d) Worm gear
Planetary gear systems can provide higher torque output at
reduced speed, useful in heavy machinery.
6. PTO (Power Take-Off) shafts are used to:
a) Increase engine horsepower
b) Transmit power to implements
c) Adjust tire rotation speed
d) Improve fuel efficiency
PTO shafts transfer mechanical power from tractors to attached
equipment like mowers or balers.
, 7. Which type of suspension is commonly found on modern
agricultural tractors for operator comfort?
a) Leaf spring
b) Hydraulic suspension
c) Rigid axle
d) Air suspension
Hydraulic suspensions absorb shocks and reduce vibrations for
smoother operation in the field.
8. What is the main purpose of a tractor differential lock?
a) Increase speed
b) Improve traction
c) Reduce fuel consumption
d) Adjust tire wear
Differential locks ensure both wheels rotate at the same speed,
providing better traction in slippery conditions.
9. Which system prevents backflow of hydraulic fluid in implements?
a) Pump
b) Check valve
c) Relief valve
d) Cylinder
Check valves allow fluid to flow in one direction, preventing
backflow and ensuring proper hydraulic operation.
10. A clogged fuel filter in a diesel tractor can result in:
a) Overheating
b) Engine stalling or poor performance
c) Hydraulic failure
d) Tire wear
