Question Statement:
An inclined-plate seed metering mechanism in a multi-crop planter is typically tilted at an angle with the horizontal in the range of:
Options:
(A) $40^\circ$ to $50^\circ$ (typically $45^\circ$)
(B) $0^\circ$ (strictly horizontal)
(C) $90^\circ$ (strictly vertical)
(D) $10^\circ$ to $15^\circ$
Answer Key:
A
Step-by-Step Solution & Explanation
Inclined plates ($40-50^\circ$) utilize gravity to roll surplus seeds out of the cells before the cell reaches the discharge cutoff point, preventing multi-seed drops.
