recovering a carrier

[alwaysbroke]

Hi my Name is Pete and all this is very much new to myself and a freind of mine. WE are in the process of getting a universal carrier out of the bush. It has been sitting for about 40 years off the beaten path in haliburton ontario. aparantly the machine is about 90 percent there. my question is what would be our first step.I assume the tracks are seized as well as the most of the components. the carrier is about a 5 to 10 mile hike into thick rocky woods. will the tracks free up easily or will I have to remove them to make life a little easier. all input would be greatly appreciated.
Thanks Pete
