Made a 2hr road trip with my 14 7230 and my hydrostatic motor temp alarm went off. It was a hot day, like 34C but we’ve worked these machines in lots of conditions like this before. Hydro rad is clean. Hydro oil temp running 135F so it doesn’t seem to be the problem. This combine has option of “economy” mode for fuel savings while roading but didn’t seem to make a difference if it was on or off, still overheated. Is the hydrostat motor going out? 850 eng hours, 650rtr hrs.
