Sometimes bigger is cheaper in the long run, like this Hydro-ax

I took the rear band off mine last year, wish I would have done it sooner. It lets more debris out. I did put chains on the front for protection in case something comes out. I have see blades break and come out the front before as well as the side, back, wherever.

I used my new landpride once with the band on it and promptly took it off. I have chains on the front and the back is open like all my other cutters have been.

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.
There is a overseas company that still makes them like that. Their videos used to be all over online. It was very rocky soil they were cutting in and I guess regular cutter with blades didnt hold up well there.

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?

Excellent video and man that is a serious land clearing cutter!

If those chains shatter like a blade then the tires should be OK.
Just cut 7 acres with 2 to 3 inch mesquite and slowly backed into them at a high level and then lowered. The stumps had a nice 4-7 large splintered pieces looking like a flower. Tires just flattened the out easily with no danger to tires.

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.

Thanks for clarifying; I couldn't get a good notion of the chain size from the pic where it's attached to the mower - lacked perspective.
