A while back, I was in the market for a new rotary cutter to replace my 5' Woods unit, with a heavier duty, 6' model. I did a lot of research on here and narrowed down my search to the Bush Hog 286/296. I wanted to find one used to save some money so it took me a bit of looking. The ones I did find were still pretty pricey considering their age/condition, so I continued my search. I ended up stumbling upon a Brown 472 model cutter that a friend of mine was thinking about selling.

I hadn't heard much about Brown Manufacturing aside from their famous Tree Cutters, which are WAY too heavy for most of our tractors. I started looking into them and only found a few owners on TBN. I private messaged some of them and had some great recommendations.
I made a deal with my friend and drove 6 hrs one way to pick up the rotary cutter. I was glad I did!

After comparing the Brown 472 (6') cutter quite a bit to the 286/296 I realized it was actually a bit heavier built than the comparable Bush Hog (the gold standard!) The deck was 7 gauge steel vs. 10 gauge and has a beefier drive shaft. Aside from that, the specs were very much similar, almost identical really. I was originally concerned that the Brown is only rated for 2" capacity vs. the 3" capacity of the BH. However, after calling and talking to Brown, and reading a few posts on the forum (I think I started a thread on it) I was made aware that the capacity is very conservative, and that if anything, should be more than the comparable Bush Hog since it was heavier built.

My 472 came with the rubber guards, and not chains. They were a little beat up so I looked into adding chains to the cutter. I emailed Brown from their website on a Sunday, and first thing Monday morning had a reply with part numbers, costs, my local dealer who can help me, and also some information on my 472 that he gave me from my serial number. He asked if I had an owners manual for it and if not, that they were available on the website.

I wrote back a quick "thank you" and he replied, saying that he attached a .pdf which was the manual for my tractor, so I didn't have to hunt around for it on my own, he went out of his way to email me the manual. I thought that was very nice of him. I ended up asking a few more questions about the rotary cutter, and Brown in general. He was very responsive and wrote back the same day I emailed him, I also asked if my cutter was quick hitch compatible, as I've been thinking of getting a quick hitch. He told me that it definitely would NOT be compatible and that I would have to cut and weld on the cutter itself to make it so.

I then asked if they had any plans to build a quick hitch compatible one, and he told me about the new 400 series rotary cutters that they have, which are already quick hitch compatible (the 415,416,417 replaced the 460,472,484). I started thinking that if I'm going to put $500 dollars into my cutter for front and rear chains, then maybe I should think about selling it, putting that $500 with the money I get for mine, and then if the price difference isn't too great purchase a brand new 416. I'm not sure if I will or not but I'm thinking about it.

Anyways, I wanted to mention this because I often see posts about good/bad customer service with companies that we all deal with, and I very rarely see much on the Brown cutters. I just wanted to share my positive experience with the Brown Manufacturing company and make sure that people are aware of another option besides Bush Hog as the gold standard of heavy duty rotary cutters.
You can check out their website here: FEATURED PRODUCTS | Brown Manufacturing | 800-633-8909
Keep in mind, that the heavy duty 400 series (actually Brown calls them medium duty similar to how BH calls their 280/290 series medium duty, but they are "heavy duty" by comparative standards) is their lightest duty rotary cutter, so if you aren't looking for something beefy (and costly I admit) then they aren't a viable option.

One other thing I want to mention, during all my 'talks' with Brown, they never once compared, or tried to "put down" any other manufacturer. That is a HUGE pet peave of mine, when I call a company about their product, I can't stand it when all they do is tell you how much better their product is than the competitors. I really respect a company that is just truthful and honest about their product and don't try to "convince" the customer that their's is "better". I like that they leave it up to the customer to make their own decision/opinions. (to be clear, I'm not insinuating that BH does this either, just making a positive note on my experience with Brown)

I know I would have been more than happy with the equivalent Bush Hog cutter as they are serious, quality built, rotary cutters, but I'm glad I stumbled across Brown, and I'll probably be a lifetime customer (unless of course I get out of "tractoring")

I did a small job the other day and used my rotary cutter so I figured I'd take some pics and post them. Of course, now I wish I got off the tractor more and took more pics :D But here is what I have.

I loaded up the trailer, probably a little more than I should have (really need that gooseneck!) with my equipment. The customer wanted a small area mowed, then some trees taken down, stumps ground, and a small area graded. I started off mowing the brush, which was mostly all small diameter overgrown weeds, however there were a few 3" hardwood saplings thrown in that didn't slow me down :D

After this job, I started doing some more "woods" mowing with a lot of small diameter pines, and some 2"-3" hardwood saplings. I'll try to post a video of mowing the pines....

Jack,
I did not remove any brush by hand. What you see in the photos is how it looked after I ran the mower over it. With the high blade tip speed of the mower, in combination with a slow travel speed, it mulches up whatever I mow pretty well. There were very few cut saplings left on the ground, many were mulched up into small pieces.

Here are a couple pics after running the box blade over it and smoothing out some of the areas.

There were about 8 stumps before I got there, from old trees being cut down. Then I cut down close to 10 more trees, with only 4 or 5 of those trees being of any size. I could not cut them with the rotary cutter, maybe if I had one of Brown's Tree Cutter's I could have taken some down, than and a 150hp tractor :D

I ground the stumps down 8"-10" below grade using the PTO stumpgrinder. Some of the stumps had good size rocks embedded into the stump, and when I hit those I stop as they will tear up the teeth pretty bad after not too long.

Here are a couple pics (the few that I took) of some of the stumps. You can see in the last couple of photos I posted that there are no stumps to be seen.

Piston,
Fantastic pics. As you remember, I'm looking at getting a Brown Mfg rotary mower. Finally found a "local" dealer - 140 mi away. He is working on getting a 415 shipped to his location. Anyhow, you are telling Jack and me that all that undergrowth, bushes etc just got ground up and disappeared when you hit it with the mower?? I've never seen a stump grinder in action. I'm sure they must use them in town - here things just sort of rot away. The cows & wildlife don't seem to mind the stumps a bit. Actually the badgers & coyotes dig into the stumps and tear them up looking for something.

Piston,

Are you looking at buying the 415 for your M6040? I would not go any less than the 416 for your tractor, in fact it would probably be the ideal mower for you if you aren't worried about it covering your tracks. The 417 is probably rated for a minimum hp of what you have, or maybe even a little more, but I think you could handle the 417 just fine if you wanted something bigger. Of course, the 7' cutter would stick out pretty far behind your tractor and might be a little cumbersome in the woods.
I'm still thinking of selling my 472 and buying a brand new 416 with chains, since it's quick hitch compatible. I'll probably keep this mower though since it works so well, and it's hard to justify the extra cost just to get a mower that is quick hitch compatible.

Anyhow, you are telling Jack and me that all that undergrowth, bushes etc just got ground up and disappeared when you hit it with the mower??
That is exactly right. I did not do any sort of cleanup with a rake or anything like that. Here is exactly what I did on that job....

Arrived, unloaded the equipment, started mowing almost immediately (I had already checked out the site a few days earlier). Since I could barely see what I was mowing, due to it being so thick, I went very slowly and mowed a lot in reverse, which you have to be a little careful doing but I haven't had a problem yet. There were a handful of old stumps already there, from old trees that were cut down a few years ago, and the customer warned me about them, so I took my time and kept a watchful eye. Many times I would back into some thick brush, and run into a stump or rock. The mower would shake pretty good, the blades would get battered, and the slip clutch would start smoking. I would then pull away or lift the 3 point hitch and the mower would go back to normal run up. Then simply go back to mowing. It didn't phase the mower at all and there was/is no damage. This thing can take a beating.
After mowing, I parked the tractor to take a couple pics, the ones I posted in post #2, the first "after" pics. I then put the stump grinder on, ground down all the stumps, and a few good sized rocks by accident :laughing: Then when the stumps were gone, I put the box blade on and started leveling a small area for a future raised bed garden that his wife wanted. I also ran the box blade over the entire area to smooth everything out and then cleanup some of the debris left behind. This is shown in my last couple "after" pics in post #5.

The reason for the good mulching action is because of the high blade tip speed, as well as slow ground speed. Many people mow with their PTO at less than 540 RPM, I almost NEVER mow less than 540RPM, because the cut is no where near as good, and when your doing paying jobs, people want a good quality cut, with nice looking results. The customer was very happy with the outcome!
I have been thinking of buying a power rake, and wish I had one for this job. If I could have ran a power rake over this area after mowing it, it would have been ready for seeding a golf course quality lawn.

Keep in mind, most of the brush I was mowing was just overgrown weeds and small diameter saplings, around 1" or less. So this really wasn't a 'heavy duty' job, aside from a few 3"-4" saplings.


I was hoping I could post a video to show some more of the 'mulching' action of the mower. I did some mowing in a pine grove with a lot of small pine saplings, around 1", and also upwards of 2"-4". I tried posting the video but apparently I can only post a link to youtube. The video's aren't anything spectacular but they show how I typically mow very slowly, and how well the mower chips up the brush.

I'll get some more pics/videos in the future and try to update this thread once in a while.

oosik,
Seriously consider the 416 as the smallest mower for your tractor. The 417 would be good as well, depending on your primary uses and how tight your woods are.

Impressive. Our woods are nothing like the pics you took. We have Ponderosa pine and birch. Anything else, with a few exceptions, was planted by some homesteader long ago and in numbers can be counted on one or two hands. Your situation looks like the western side of WA state. I'm sure the tractor would take a 416 - it would just be navigating thru some of the tight areas. I watched the tree cutter videos on the Brown site the other day - those get down right frightening!! I think I would be wearing a full face shield even if I was in a cab unit. Piston, again thanks, your experience is invaluable for me.

I really think you should cut down all the stump before mowing. I have many customers break their mower when their working mower meet the stump. this will break the blade directly, and then break the belt and gear in the gear box. The worst case is: you mower is stuck by the stump and stop spinning, but you tractor is still high speed output, maybe 540 r/m or higher, then you can image what will happen next.
