Yeah, I feel your pain with equipment. Takes an extra 1/2 hour or so to get going with all the equipment when its cold. Even with it all plugged in, it just takes longer to get rolling.
I have a tree service with all the normal equipment and then some.
I do have to say that the Bucket truck will BLOW YOUR MIND. 2002 international 4800 4x4 with at DT466 engine. It will start no matter what! I am not kidding, it will actually start quicker in the winter at -5 F,( not plugged in, hasn't been started for a month ) than it does in the summer!
Surprises me every time and I've owned it for 5 years.
