Category: Class F -7- Engine - Level 3

Your vehicle has a foot-operated clutch. This clutch is slipping. What dangers can result from this?

The engine could become too hot

When driving downhill, the brakes could be overloaded

The gearbox could be overloaded

At high traction outputs, the clutch is overloaded and fails

What is the purpose of the differential lock of a motor vehicle?

It enables the gears to be shifted in half steps

It enables the drive wheels to be driven at different wheel speeds when cornering

It creates a rigid connection between the driven wheels or axles

It divides the gears into a slow and a fast driving range

Category: Class F -7- Engine - Level 3

You are performing a work operation with your tractor in which the engine speed and driving speed of the tractor should remain constant for a longer time. How should you behave in this case?

I should only use the accelerator pedal to be able to quickly adjust the speed

I should preferably use the hand throttle to avoid speed fluctuations

I should adjust the speed during driving by manually performed shifting operations

If my tractor has an electronic control for the engine speed, I should use this control

Category: Class F -7- Engine - Level 3

You are driving a vehicle combination consisting of tractor and trailer up an incline. What must you pay attention to regarding the driving force to overcome the gradient resistance?

The gradient resistance must always be greater than the driving force of the tractor

The driving force of the tractor must be greater than the driving resistances

The gradient angle must always be greater than the driving force of the tractor

The driving force of the tractor must always be less than the driving resistances

What advantages do continuously variable transmissions have over manually shifted transmissions?

They enable speed changes without having to stop

They have an integrated engine-transmission management. This allows the engine to always be operated in the speed range optimal for low consumption

They have an integrated fuel-saving mode

Engine power and engine speed can be coordinated with the driving speed even under load without having to stop

6 / 18

Category: Class F -7- Engine - Level 3

Your vehicle has a foot-operated clutch. How can you tell that the clutch is slipping?

The clutch pedal becomes easy to operate

The clutch pedal becomes stiff

During strong acceleration, the engine speed increases while the driving speed hardly changes

When driving downhill, the braking effect of the engine is only weak or not noticeable

7 / 18

Category: Class F -7- Engine - Level 3

What factors influence the gradient resistance of a vehicle combination consisting of tractor and trailer?

The road condition

The driving speed of the vehicle combination

The total weight of the vehicle combination

The gradient angle of the roadway

8 / 18

Category: Class F -7- Engine - Level 3

You are driving a vehicle combination consisting of tractor and trailer. What driving resistances occur during driving?

The rolling resistance of the tires on the roadway

The acceleration resistance of the vehicle combination during acceleration

The air resistance of the tractor

The gradient resistance of the vehicle combination when driving on inclines

9 / 18

Category: Class F -7- Engine - Level 3

How can you operate your tractor in an energy-saving manner?

I choose the lowest possible tire pressure for road trips

I choose the lowest possible tire pressure for work in a field

I choose the highest possible tire pressure for road trips

I choose the highest possible tire pressure for work in a field

10 / 18

Category: Class F -7- Engine - Level 3

What does the rolling resistance of a vehicle combination consisting of tractor and trailer depend on?

The tire pressure of the tractor and the trailer

The total weight of the tractor and the trailer

The gradient angle of the road being driven on

The road condition or the road surface

11 / 18

Category: Class F -7- Engine - Level 3

What advantages do powershift transmissions have over manually shifted transmissions?

They enable speed changes without having to stop

The transmission requires fewer gear stages to enable low fuel consumption of the engine

Each gear can be subdivided (split) multiple times

Engine power and engine speed can be coordinated with the driving speed even under load without having to stop

12 / 18

Category: Class F -7- Engine - Level 3

Your vehicle has an automated transmission. What must you particularly pay attention to in driving operation?

If high traction outputs are required, I give as little gas as possible

When driving downhill, I choose the shift position "N"

When driving downhill on a steep gradient, I choose a low driving stage

Before towing my vehicle, I should read the instructions in the operating manual of the vehicle

13 / 18

Category: Class F -7- Engine - Level 3

What can you check on the clutch of a tractor?

The free play of the clutch pedal

Complete release when the clutch is operated

Complete engagement when the clutch is not operated

The temperature of the clutch disc

14 / 18

What is the purpose of the differential gear of a motor vehicle?

It enables the gears to be shifted in half steps

It divides the gears into a slow and a fast driving range

It enables the drive wheels to be driven at different wheel speeds when cornering

It enables the drive of auxiliary consumers

15 / 18

Category: Class F -7- Engine - Level 3

You are driving a vehicle combination weighing 20 t. The tractor has a foot-operated clutch. What should you avoid when driving to protect the clutch?

Starting in too high a gear and letting the clutch slip for a long time

Prompt engaging of the clutch

Starting with high engine speed and letting the clutch slip for a long time

Constantly loading the clutch pedal

16 / 18

Category: Class F -7- Engine - Level 3

Your vehicle has an automated transmission. You want to have the vehicle towed. What do you pay attention to?

That I definitely shift to the position "D" when being towed

That I definitely shift to the position "P" when being towed

If possible, I call a professional towing service

I follow the instructions in the operating manual of the vehicle exactly

17 / 18

Category: Class F -7- Engine - Level 3

What must you pay attention to regarding the weight of your tractor so that the tractor is operated in an energy-saving manner?

For heavy traction work, sufficient ballast must be mounted to avoid increased tire slip

The tractor should be as heavy as necessary for the respective operation

The tractor should always be loaded with ballast up to the maximum permissible gross weight

The tractor should be as light as possible
