For a bigger tractor like yours, I can tell you: They're heavy! A neighbor bought an a Kubota M6040 with R4s after Snowmageddon, and found he needed chains for good traction in snow. While it can be done alone, it pretty much takes two people to put them on. They go on in November and stay on until April, snow or no snow!
On larger machines, you put a strap through the end of a "laid out" chain, then wrap the strap around the tire and drive the chain on with the strap acting like a winch. A helper is very useful for this & timing of snagging the strap out (before it's trapped) can be tricky. Heavy is still heavy but this does make the job much easier than completely man handling it.
