Wheat 11 (80 ft wide) and Wheat 12 (40 ft wide): A standard oscillating sprinkler throws roughly 20–25 ft per side from center. For Wheat 12, move the sprinkler to two positions along the run and run each position for the times above. For Wheat 11, use four positions or consider a traveling sprinkler on a hose track down the center — it walks itself and handles wide runs without you moving equipment manually.
