I'm not sure what size your JD35D is but I've seen brush cutters for excavators on small Bobcat brand and all the way up to Hitachi 400s. Most were the drum or flail type. It usually requires having the high output pump option so you may need to investigate that.
Here are a couple of companies and I know I've seen others including Bobcat if yours is a smaller size.

www.rwfbron.com

I've also seen some on ebay.

I did a quick Google search for "excavator mounted brushcutter" and came up with a few

From the diffrent bush cutters I have seen the DENIS CIMAF horizontal shaft cutters work quite well, they cut and grind the brush. You can also grind down stumps. The fixed hammers are the way to go. Flails don't work very well on brush, they work best on grass and low shrubs. The trouble you may have is the size of your excavator. Is it the predesesor to the 35 ZTS John Deere? You may want to look at the DAV line (vertical shaft) from DENIS CIMAF.
Also, before you invest in one of these units, go see one work. They are very slow to use for yearly maintinace. If I had the money I would hire out the major cutting for the first trip. After the inital work is done, buy a farm tractor with an off-set bushhog to do yearly maintinace after that. :my2c:
If you don't fall off your not going fast enough!

Good point on the fixed hammer type. I have been toying with the idea of mounting an old tiller on the front of my PB200D and modifying the teeth on the drum to cut small brush that infects our trails. For the big trees and stumps I have been using the "other" cat. Some of our trails are only accessable in the winter though which can be messy. Our recieved a grant to clear a 30 miles of new trail using an Hitachi EX200 and this D3G.

Alamo Industries is another brand to look at for brush cutters.

Hi all,

My name is Frederic Denis and I take care of marketing for DENIS CIMAF Inc. I've noticed that quite a number of visits on our website originated from this thread (thanks for traffic, by the way :)

I just wanted to clarify a detail: The image that was posted in this thread represents a brushcutter-chipper from the DAH product group (the DAH-050 to be precise). The technology of its rotor is very productive, with fixed knives and sharpenable, bolt-on blades. However, the smallest model we currently have for this can go on an excavator down to 7 tonne (maybe 6.5 tonne, we'll try that in the next weeks).

We do have something to fit on a JD 35, though. That would be either the DAV-400 or DAV-450. These little beasts use a horizontal disc with two swivelling knives. It's not as aggressive as the DAH models, but its power requirements are therefore lower. And as there's fewer moving parts, the final weight is quite less. It's still industrial-class, so it's not the cheapest attachment you'll get. But it's rugged and meant to last...

See:

DAV-450 image gallery
DAV-400 image gallery

Uh-oh... I've just realized that you can't zoom on any of these thumbnail pictures, I'll have that fixed in the next days. :oops:

If someone needs any extra information on our products, you are welcome to email me here, or at the office at frederic.denis@deniscimaf.com. Or call toll free 877-279-2300. Or call 1-deniscimaf (non-toll free but easier to remember, North Carolina area code).


Best regards to you all,


Frederic Denis (Fred)

Welcome aboard. It is good to hear from manufactors, as they all are a wealth of information. :)

I saw one of these in action cutting a 15 wide path for a new snowmobile trail re-route through a section of woods:

The trail was left with a lining of tree mulch and NO STUMPS!
A local CNY company uses it, Joe at Mohawk Valley Mulch, in Rome, NY. He could give more specifics like costs and equipment requirements. The drum is something he rents and the Bobcat is one of the bigger ones they manufacture.

Regarding the drum-type brushcutter, here's a quick overview of what's available:

1. Swinging-tooth type (Seppi, older ROWMEC heads, older DENIS CIMAF heads)

That's the type where you have a number of knives on the rotor, usually each mounted on its axle. Can make a clean finish, but it's not the most productive because the angle of attack changes all the time.


2. Carbide hammer type (FAE, Fecon, the Bobcat foresty cutter is one of these,...)

There are many, many companies using this technology. Each "cutting tool" is fixed, so the angle of attack doesn't change. Good if you need to mix material into the ground while mulching. But for ground-level and above operation, they are power-hungry. And costly to operate when hit too much granite...


3. Fixed knife type (DENIS CIMAF, of course ;) , but also others like Loftness...)

Well, you saw the picture posted previously... The knives are real cutting tools so for ground-level or above operations, that's the most efficient way of working (just as comparing cutting wood with an axe rather than with a hammer). Doesn't like rocks either, but tools are cheaper to replace than carbide. Excavator-mounted heads will get 300+ h of life (depending on the operator, of course :rolleyes: )... And blades are sharpenable, which keeps them productive until they are worn-out. Big names in carbide hammer are working/introducing fixed knife types now...


See this page for more information on DENIS CIMAF rotor technology


Again, I stay at your disposal for any questions you guys might have...
