Agricultural Mechanics 2 Review

What is the purpose of a torque wrench in agricultural mechanics?

• To harvest crops

• To repair irrigation systems

• To measure soil pH levels

• To accurately tighten bolts and nuts to specific torque values

Explain the difference between a disc harrow and a chisel plow.

• Disc harrow is manual, chisel plow is automated.

• Disc harrow uses chisel-like points, chisel plow uses cutting discs.

• Disc harrow uses cutting discs, chisel plow uses chisel-like points.

• Disc harrow is used for planting, chisel plow is used for harvesting.

What safety precautions should be followed when operating a tractor?

• Wear loose clothing that can get caught in the machinery

• Always operate the tractor at maximum speed

• Follow manufacturer guidelines, wear appropriate clothing, use seat belts, avoid steep slopes, be cautious of blind spots, keep children away.

• Allow children to play near the tractor while in operation

Describe the function of a hydraulic system in agricultural machinery.

• The function of a hydraulic system in agricultural machinery is to transmit power using fluid pressure to perform tasks like lifting heavy loads or operating attachments.

• Agricultural machinery hydraulic systems are primarily used for cooking food

• The hydraulic system in agricultural machinery is used for watering crops

• Hydraulic systems in agricultural machinery are designed to play music

What are the common types of welding techniques used in agricultural mechanics?

• MIG welding, TIG welding, Stick welding

• Spot welding

• Plasma welding

• Arc welding

How does a combine harvester work and what is its primary function?

• A combine harvester works by planting seeds, watering the crops, and harvesting the fully grown plants.

• A combine harvester works by herding livestock into a designated area and then processing the animals for meat production.

• A combine harvester works by cutting, threshing, and cleaning grain crops in one pass. Its primary function is to efficiently harvest grain crops.

• A combine harvester works by flying over fields and collecting crops using a vacuum system.

Discuss the importance of proper maintenance of agricultural machinery.

• Proper maintenance of agricultural machinery is essential for optimal performance, longevity, and safety, leading to increased efficiency, reduced costs, and higher yields.

• Proper maintenance leads to decreased efficiency

• Neglecting maintenance can improve machinery performance

• Regular maintenance does not impact safety

What are the key components of a typical irrigation system used in agriculture?

• fertilizer

• sprinklers

• drones

• hoses

• pumps, pipes, valves, emitters, controllers, sensors

Explain the role of bearings in agricultural machinery.

• Bearings in agricultural machinery are used for decoration purposes only.

• Bearings in agricultural machinery are unnecessary and can be removed without affecting performance.

• Bearings in agricultural machinery reduce friction, support rotating shafts, ensure proper alignment, and increase efficiency.

• Bearings in agricultural machinery are designed to increase friction and slow down rotating shafts.

What are the steps involved in troubleshooting a malfunctioning engine in a tractor?

• Inspect exhaust system, check suspension system, examine fuel system, verify air intake system, assess cooling system

• Check tire pressure, inspect windshield wipers, examine radio system, verify seat belts, assess air conditioning system

• Inspect transmission system, check steering system, examine brake system, verify hydraulic system, assess electrical system

• Check fuel system, inspect air intake system, examine ignition system, verify cooling system, assess exhaust system
