Answer: Option B
Solution (By Examveda Team)
Step 1: In agricultural machinery, slip refers to the difference between the theoretical distance traveled by the implement and the actual distance covered on the field.Step 2: For a seed drill, the drive wheel rotates the metering mechanism which delivers seeds into the soil.
Step 3: Due to soil resistance and field conditions, the drive wheel does not rotate exactly as per theoretical movement and tends to slip.
Step 4: This slip is generally positive, meaning the actual distance covered is less than the theoretical distance.
Final Answer: Seed drill has positive slip.
