Hot air on the operator, coolant leaks and a low-fuel code. A 4720 open station blowing hot air on the operator's legs (a reply suggested heat-resistant pads on a bracket), an owner with a coolant leak on a 4320 asking whether 4320, 4520 and 4720 owners see it too, and a 290-hour 4720 hydro that died mowing with an error a reply read as low fuel from a previous day. Threads read: 1, 2, 3.
