Concept:
Harvesting pattern is the path followed by a harvesting machine in the field. A proper pattern reduces turning time and improves field efficiency.
Step 1: Combine harvesters are used for harvesting, threshing and cleaning in one operation.
Step 2: In the circuitous pattern, the machine moves around the field in a continuous path.
Step 3: The direction of cut remains to the right.
Step 4: This pattern is commonly used with combine harvesters because it reduces unnecessary movement.
Step 5: Therefore, the correct answer is:
\[
\boxed{\text{Circuitous pattern}}
\]
