Step 2
5.1.2 State THREE advantages of using machinery in the harvesting process.
Answer
Three advantages of using machinery in the harvesting process are:
- Single operation - machinery allows for simultaneous tasks, increasing efficiency.
- Less time-consuming - machinery significantly reduces the time required for harvesting.
- Labour saving - fewer workers are needed, leading to reduced labor costs and improved productivity.

Step 4
Step 5
5.2.1 Use the following information (excluding value-added tax) to calculate the running costs of a combine harvester. Show ALL calculations.
Answer
To find the total running costs, add the following:
- Fuel: R8 100,00
- Oil: R1 200,00
- Filters: R1 500,00
- Labour: R3 000,00
- Parts: R8 000,00
Total = R8 100,00 + R1 200,00 + R1 500,00 + R3 000,00 + R8 000,00 Total = R21 800,00.
Step 6
5.2.2 Calculate the value-added tax (15%) payable on the total running cost of the combine harvester.
Answer
To calculate the VAT, apply the formula:
VAT = Total Running Cost x Rate
Given: Total Running Cost = R21 800,00 Rate = 15% (or 0.15)
Calculation: VAT = R21 800,00 x 0.15 = R3 270,00.
Step 7
Step 8
5.3.2 Determine the right time to sell the tractor by analysing the data in the graph above AND give TWO reasons for your answer.
Answer
The right time to sell the tractor is during year 4. The reasons are:
- There is one year left on the maintenance plan, which adds value.
- The tractor maintains a higher value compared to selling it in year 6.
Step 9
5.3.3 State THREE actions a farmer can take to minimise excessive depreciation on the value of second-hand implements.
Answer
Three actions a farmer can take are:
- Repair or replace broken or worn parts to maintain functionality.
- Store implements properly to prevent damage from the elements.
- Service equipment according to the user manual to ensure optimal performance.
Step 10
5.4.1 Identify components A, B and C and state TWO functions of EACH.
Answer
A. Top link - Functions:
- Adjusts the angle of the implement in relation to the tractor movement.
- Serves as the connection for the three-point mechanism.
B. Hydraulic pump - Functions:
- Provides pressure to the hydraulic system of the tractor.
- Enables movement for the attached implement.
C. PTO drive shaft - Functions:
- Transmits driving power from tractor to implement.
- Provides angular movement between tractor and implement.
Step 11
5.4.2 Describe THREE important safety precautions applicable to component C.
Answer
Three important safety precautions are:
- Never climb over the driving shaft when in motion.
- A safety screen must be in place to prevent contact with moving parts.
- Always ensure the safety screen is highly visible to alert others.
Step 12
Step 13
5.5.2 Give FOUR reasons for equipping a tractor with a clutch.
Answer
Four reasons for equipping a tractor with a clutch are:
- Engine drive needs to be disengaged when gears are changed for smoother operation.
- The drive should disengage when the tractor is started to prevent sudden movements.
- The clutch allows for variable speed control to match work requirements.
- The operator can stop the tractor or implement without stopping the engine.
