You may read of Elijah’s appointing of his successor: “He . . . found Elisha the son of Shaphat while he was plowing with twelve spans before him.” (1 Kings 19:19)

Elisha was taking part in a major plowing operation when he was called as a prophet. That likely places the time in Tishri (September-October), when the extreme heat of the summer was past. The early rains had begun to soften the soil, making it possible to do plowing, followed by sowing.
