NE Nebraska
My opinion on the 7rs is that they push air through the oil cooler and radiator versus pulling. With emissions and everything thing else under the hood, not enough cooling area. 7280r last 2 days spraying running ivt, hydraulic spray pump and boom functions. Hyd temp 185-200. Coolant temp 180-210. Fan will cool coolant to 180 and the hydraulic oil will stay near 200. Air temp mid 80’s
