Hello and welcome to the site. I use a Max IV for ice fishing for the safety factor as well. First of all if you plan on running tracks the machine will have to be set up for that. It must have three bearings per axel which supports the axel all the way to the hubs to handle the extra stress of the tracks. You can also check the bearings by jacking the wheels off the ground and check for play by trying to wiggle the wheels. Check the sprockets and chains for wear. This will give you a good start what to look for. If you have more questions feel free to ask. There's tons of great help and advice on here.
What it lacks in ground clearance it makes up for with traction.
