Living in Alaska would make me want to consider getting a cab for my tractor. /forums/images/graemlins/ooo.gif
Here is an unorthodox way I have used to start engines on very cold days(and it works great). IE: I had a 8 hp Tecumseh powered log splitter that set outside and an old Beaver III 16.5 diesel that set outside as well.On cold days in the single digits/teens the old wood splitter was a bear to pull the rope on and get started,the tractor would not start,here is what I done to get them started.
Fill 3 or 4 five gallon buckets full of hot tap water and have them filled and setting next to the log splitter or tractor and pour the water over the engine 2 to 3 buckets full and then immediately proceed to start the engines,it never failed to start the engines or cause me any other problems,go ahead and laugh but it worked for me and I would not hesitate to do it on my JD4400. /forums/images/graemlins/wink.gif
