Plugged in at 8ish. Started tractor at 10.
Overbite low was 25. About 28 at 8am. 30 by 10 am. Some wind.
Front and top of hydro reservoir warm.
Rad hose above heater hot, intake on water pump warm. But no flow thru to radiator.
Engine took 2 crank overs to start. which is a improvement over the usual cold start.
Batteries could use a trickle charge.
The real test will be when its in the teens.
That is when I have a real hassle getting up enough RPM"s to start it.
