Understanding Combine Harvesters

What is the primary function of a combine harvester?

• To plant seeds

• To cut, thresh, and separate grain from chaff

• To irrigate crops

• To fertilize the soil

Which of the following is NOT a part of the combine harvester's process?

• Cutting the crop

• Threshing the grain

• Separating the grain from the chaff

• Planting new seeds

What is the oldest design of a combine harvester?

• Rotor design

• Cylinder and straw walker design

• Hybrid design

• Twin rotor design

Which design of combine harvester is most prevalent today?

• Cylinder and straw walker design

• Rotor or twin rotor design

• Hybrid design

• Manual design

In the hybrid design of a combine, what is used to thresh the grain?

• A rotor

• A cylinder

• A set of straw walkers

• A header

What is the function of the header in a combine harvester?

• To thresh the grain

• To separate the grain from the chaff

• To cut the crop and move it to the feederhouse

• To plant seeds

Which part of the combine harvester is responsible for moving the crop to the feederhouse?

• The rotor

• The cylinder

• The header

• The straw walker

What is the main advantage of using a combine harvester?

• It reduces the need for water

• It combines multiple processes into one machine

• It increases the planting speed

• It fertilizes the soil

Which of the following is a type of header that can attach to a combine?

• Plow header

• Seed header

• Crop-specific header

• Irrigation header

What is the role of straw walkers in the original combine design?

• To cut the crop

• To thresh the grain

• To shake the grain from the crop

• To separate the grain from the chaff
