Snow Job...
First, thanks to folks for the advice about storing old electronics in sub-zero temperatures. My main concern was the idea of chips popping out of sockets, or cracking. Humidity isn't really an issue here (it's a dry heat/cold) and I definitely know better than to bring something in from the cold into a warm and humid environment. The slow warming/cooling trends sound like they won't be much of a problem. A bigger concern, as Kevin_Bunny points out, is leakage from any backup batteries. Most of these things don't have them, so that shouldn't be a problem.
Today was a day of moving snow, or trying to. There's too much snow here for the snowblower to be able to do much with, so I thought I'd try bringing the tractor out of the shop and use it instead. Easier said than done! First, I had to dig my way out of the back of the shop; a slow process, but I managed. Once the tractor was out in the main yard, I used it to clear the parking area near the house, and almost got stuck a few times. The problem is that a MF-65 is not (relatively) a heavy tractor, weighing about 3500 pounds. It's also only a 2WD tractor, whereas many of the newer ones are 4WD. Perhaps if I had chains on the rear wheels it would help, but at this time I don't have that luxury. I had hoped to clear the snow from the front of the horses' paddocks, but that just didn't pan out. It's amazing how hard the wind can pack down snow; The snowpacks are almost rock-hard, and with the tractor's rear wheels just spinning, there was nothing I could do to move the snow away. All I was doing was spinnging my wheels and chewing up the ground if the tractor dug its wheels in that far. It looks like we'll be continuing to use a sled for our work around the paddocks. At least I was able to clear the parking area so we can get our vehicles in and out without getting stuck.
It's amazing how tired one can get driving a tractor around. Granted, the machine is doing most of the work, but with these old tractors there's a fair bit of "legwork" to make them do their thing. You're constantly on the clutch and brake, and it's nothing like the system in a car. That, and a tractor isn't exactly a smooth, nor a quiet ride. My legs feel like Jello, and my butt is numb after riding that thing for several hours!
