PATRIOT SERIES - 4 MODELS FROM 18,3 TO 36,5 M BOOM The cab-forward, rear-engine configuration gives Case IH Patriot sprayers their distinctive look and their performance edge. This design puts the static weight of the cab and engine over the front and rear axles. The dynamic weight of the product tank is in the center of the machine, so there is more even weight distribution when the tank is full and the booms are out.
