This just reminded of how my grandfather had his rotary mower set up -- which if I'm recalling correctly was with short blades connected to the spindle which then held a chain with a set of Y-shaped knives (like would be on a flail mower) at the ends.

It handles it with absolutely no problem. I've cut 3" stuff easily, some times even 4" going a bit slower.
We do mow a lot slower because most of the time we are just backing up against brush higher than the tractor. Sometimes there are some hidden surprises there like open old water wells anywhere from 6 ft to 15ft wide.
Here is a video. Not mine and it's a bigger JD though but doesn't matter anyway.

I too see how this thread changed from chain *guards* to chain *blades*... but dang that stuff you're cutting looks like it'd be very hard on tires after it's cut.
How do the chains hold up over time, do they get frayed and broken over time?
The small chain we use is 3/4" high strength chain.

To clarify - here chain size measures the diameter of the metal in the link (the "wire" size), not the distance across of or the length of the link; each 3/4" chain link would be about 4" (10cm) long.
Does your cutter use that, or something more like a 9mm (wire size) chain?
The chains hold fine and are not too expensive to replace. With time and work, the last link of the chain ( the one that gets the most abuse) will get thinner and actually sharper over time. I need to take a picture of mine, next time I take the mower out again. It is getting a shape of a blade lol.
It's also not that expensive to replace. For instance, my 50" mower, takes two pieces of chain about a little over a foot each.
Yes, I know that but that's a good point to clarify. It's actually the diameter of the "wire" as you called it. So it's a big a chain. The length of the chain link I don't really know but looking at specs, they mentioned a bit over 2". Doesn't seem to be anywhere near 4" though. It's been a year since I've use mower. I will only start my mowing/land clearing "season" in a month or so.
It's grade 80 chain by the way.
Here a link from a US supplier I've found. It's easier for you to get an idea.
