It is amazing that you were able to do that.
Some people can't get them started with the glow plugs. :laughing:
For those who are new to winter starting, and operating:
Remember, as it gets cold, your glow plug time gets longer. Really cold conditions require 30 seconds or more.
You also have thicker air in the winter, so you get more air in the intake. That requires more fuel to get the right mixture to start easily. A good starting point for a really cold weather starting is open the throttle 15-20%.
You need to experiment with your tractor to find the right combination of glow time, and throttle position that works for you.
If it does not start by the count of 5, don't crank it until the battery dies. Go back to the glow plugs, and run them longer, and or change the throttle position.
With experience, you can get fast, easy starts.
Diesel engines do not create much heat at idle speeds. Open the throttle to around 1,000 rpm or so, (or, any fast idle speed it runs smoothly at), during the warm up.
Don't forget about the extended warm up times, as per your manual, for the 5 gallons of oil in your transmission.
