I have been operating snow vehicles for 40 years. I started in Thiokol 1404, DMC/LMC 1450, LMC 1500, Pisten Bully 100, and now a Tucker Terra 2000XL. The only machines I have had blades on are the PB100, LMC 1500, and the Tucker. Most of my time has been in Northern California and Nevada in what is known as Sierra Cement and all of my time is in the back country going to communications sites.
I purchased the Tucker because of the great ride, quite, and it's deep snow ability. I have to admit that I had to learn how to operate the Tucker after all my experience in 2 track machines. I found you do not operate a Tucker like a two track machine, and yes I have been stuck in the Tucker. I have never been stuck so bad that I couldn't get out with a little shoveling or winch. The one thing the is obvious is the high CG. It will not side-hill anything like a 2 track machine. Hence the need for a blade. I can however run in deep snow that a two track machine would struggle with. Most of my customers are much more comfortable with cutting a road in either type on machine.
It's a decision you will have to make for your conditions. We tow our Tucker all over to many different sites, and it's a great machine. There are at least five Tuckers here in the Truckee area. Four are used to get to cabins, and mine is the only one that works for a living,, I think.
Here are a few of pictures of our Sno-Cat at work.
