If fuel in the tank is already gelled, adding anti-gel additive probably won't help until you thaw what is in the fuel lines, filters, and injector pump. With either my car or tractor, I added the anti- gel before single digit or sub- zero weather hit. Used a small squirt of starting fluid in the tractor if needed, and cycled the glow plugs twice before starting the car.
I also found plowing my driveway with the tractor to be a pain. I bought a 26" electric start snow blower, and found I'd rather use that because it tosses the snow far off the driveway. All I need is two round trips of 500 feet each way for a quick clearing of an 8 foot wide escape route. Then a few more minutes to clear walks and aprons. Best time to buy a snowblower is in mid-summer when Global Warming fools are thinking the sky is falling, and it will never snow again.
