Here is an update on cold starting my 1023.
Saturday night I took the tractor to my In-Laws so we could fit the hooks and pins on the root rake we were building for it. I parked it outside the garage because there was a vehicle parked in the work space.
Sunday Morning it was -9 F (not sure of the wind chill) and I went over and tried to start it. It did not start for me the first or second time. The the third time I cycled the glow plugs 3 times and it wanted to start, but the battery was too weak (or didnt have enough cold cranking amps) at that point. We had to put the charger on it for a few minutes, cycled the glow plugs again it started up.
