I'm going to put a cab on my plow tractor for this winter. I was going to use the electric defroster that I keep on the dash of my van. I just noticed that a True Value flier that starts next Wednesday has the defrosters for $10 minus a $5 mail in rebate. They work pretty good on a small area. I'm going for the extra one.
They also have a 53 LED light with a magnetic base for $10. I like to have an extra self powered light because I've lost the tractor lights at night in the middle of a storm. It was not fun having to drive home with just a small hand flashlight. Good Luck, Rick
