How much would a Husqvarna LT1238 lawn tractor and a Husqvarna 8024STE be worth? Both of them are in GOOD condition, and roughly 6 years old.

The rule of thumb is that a used item would sell for 20% of what the same item bought today brand new would cost. If it's in perfect condition, a cream puff, you could get substantially more also if you have good and complete maintenance records to show them. If you know of any local banks that do consruction or small business type loans you could go in on a slow afternoon and ask, some of them have a book like the Blue Book for cars that they use if they want to make a loan to someone on equipment purchase. Or just look in the classifieds in a newspaper from a local, large city. That will give you an idea of what other people are getting in your area.

That would all depend on the location of where you are located. And the time to sell a snowblower would be a day or two before a snow storm is predicted.
