3. Explain the principles of operation of a diesel engine?

A diesel engine operates on the principle of compression ignition. In a diesel engine, the air is compressed to a high temperature and pressure, which causes the diesel fuel to ignite and burn. The following are the main principles of operation of a diesel engine:

• Intake stroke: The piston moves down the cylinder, drawing air into the cylinder.
• Compression stroke: The piston moves up the cylinder, compressing the air.
• Power stroke: The diesel fuel is injected into the cylinder and ignites, causing the piston to move down the cylinder.
• Exhaust stroke: The piston moves up the cylinder, expelling the exhaust gases from the cylinder.

4. How do you align a combine harvester?

To align a combine harvester, the following steps can be taken:

• Check the combine harvester’s frame for any damage
• Level the combine harvester
• Adjust the combine harvester’s header
• Adjust the combine harvester’s threshing system
• Adjust the combine harvester’s cleaning system

5. Describe the safety precautions that should be taken when working on agricultural machinery?

The following safety precautions should be taken when working on agricultural machinery:

• Always wear appropriate safety gear, including gloves, safety glasses, and hearing protection
• Never work on machinery that is running
• Always disconnect the power source before working on machinery
• Never put your hands or feet near moving parts
• Be aware of your surroundings and be careful not to trip or fall
• Never work alone on machinery

8. Explain the principles of operation of a GPS guidance system?

A GPS guidance system uses satellites to determine the position of a vehicle. The system then uses this information to guide the vehicle along a predetermined path. The following are the main principles of operation of a GPS guidance system:

• The GPS receiver in the vehicle receives signals from multiple satellites
• The receiver uses the signals to calculate its position
• The receiver then sends the position information to the guidance system
• The guidance system uses the position information to calculate the vehicle’s heading and speed
• The guidance system then uses this information to guide the vehicle along a predetermined path

9. How do you maintain a fleet of agricultural vehicles?

To maintain a fleet of agricultural vehicles, the following steps can be taken:

• Regularly inspect the vehicles
• Perform regular maintenance on the vehicles
• Keep the vehicles clean
• Lubricate the vehicles
• Repair the vehicles as needed
• Keep a record of all maintenance and repairs

10. What are the different types of agricultural equipment used for planting crops?
