Brush Hog mods

[ptsg]

I was in a place today that would have been a good test for it, to see if it could work circles around a skidsteer I posted a couple of pictures in the other thread, good luck and keep us posted.

It would. That right there is the perfect place for these cutters. A simple 75HP tractor and a medium duty cutter would've taken care of it easily.

In the skid steer mowing thread the topic of rotary chain mowers came up.
I got to looking around and found a couple of videos from guys who had cut their blades back and added chains.
Found an old model 12 BH 5 ft and went at this mod. Nothing pictured here is pretty. We just wanted to experiment with the chains or cables.
We mow rocks at times and it plays heck with the steel blades.
This picture here what we saw in our initial (fact or fiction) search

The company I work for has done safety testing on using chains in place of blades on rotary cutters. There is an impact test ASABE S483
that a rotary cutter blade must pass. The chains explode in many small pieces (bullets) when you hit the 2" diameter stake. Using chains on a rotary cutter is dangerous, use caution.

I find that a little bit hard to believe considering the amount of rocks, logs, pieces of steel, etc I've hit with mine.

I'm interested to hear what kind of chain you tested with. I've heard more cases of broken blades (even though not many people use them here) than I've heard of chains broken and throw stuff everywhere. I've even heard cases and seen pictures where the broken blade landed right on the inside sidewall of the tire.

People over here have been using chains for over 40 years. Yes, chains can break, usually the first link that sees all the beating will wear out thin and then crack one side. Eventually crack the other side. Both halves will land where it breaks. Not the entire chain breaks and definitely won't throw small pieces like bullets.

Some folks seem to think these cutters are some kind of redneck mod. They're not. They meet all the safety standards they need to meet. They're for sure not any more dangerous than a regular brush cutter is.

I wonder what grade chain they used in their experiments too.

No matter the grade, I'd guess the folks running chains are not replacing them when they wear.....

Same thing can be said for blades, how many think to inspect blades after encountering something significant or just check them annually for normal wear? Of the people I know who own a rotary cutter, it's hook it up and go, only looking under it if something has tangled up like fence wire.

IMHO blades or chains are both dangerous if maintenance and simple inspections are part of it.

Here is a picture of mine back in 2019. Around 200-ish hours on this set of chain. I run mine very close to the ground, so it tends to dig a lot and wear out faster. I would say 400 to 500 hours per set of chains is a good time frame, but depends on a lot things.

You can see how thin the chain gets on the end that see all the work. You can also see the cracked link I keep talking about. This how these chains wear out. The link gets so thin that eventually it breaks. People will often run them till they get 1 to 2 links shorter before they get a new set, basically reducing the cutting width till it's a bit too much.

I still haven't bought a new set, even though it's less than €30.

Well here is a company with a few Canadian dealers, some very nice looking pieces of equipment;
This first one is my favorite in a quick look,

What size of chain did you end up going with? Looks small in that mower. Cables won't work very well because they don't really have much weight at all.

For anyone interested, here is one of these cutters working:

Also, how one of these mowers look underneath and on the top:

Those little chains 'round the edges are 'new to me' and an interesting feature. I also noticed the lack of a wheel on the back. I'd assumed 'they all had one.' Live and learn. Thanks for sharing the video
