This thing is amazing - Ive watched bunches of those saw blade style stump grinders, but this thing takes the cake hands down! Didnt take much more then a minute to dig it right to the ground
@rotorstumper That would help alot. My grandfather was always on me about the angle of the PTO. Back in the old days, they wouldn't old up if you went past 45 deg. Nice to see inovation with the double joint rated at 240 hp
This looks a lot safer than a traditional trailored stump grinder. It is slow and it doesnt not spit would chips every where that could lead to injury like a stump grinder would. Well done if i must say so myself.
not in the city, we mostly work in peoples yards, fences, gates, soft lawns & landcapeing I run a rayco r g 50 super that has to fit thru very small gates & it still tears up lawns if its too wet thanks for thinking about it--John
this has got to be one of the best idea i have seen in many years so simple and so awesome good this is centuries ahead of all other stump remover tools out there what is the price tag on it delivered in Denmark
+lytken Thank you for the comment Is over 50 years, physically demonstrable and not in words, we build these machines. Few have our experience Write to ferrirotor@libero.it specifying the request with the data of the tractor.
Very impressive.It might be expensive but it certainly does a much better job than the usual rapidly rotating other grinders which simply disperse dust all over the show.
How far below the surface does it cut. We plow 16" deep periodically. Wouldn't want to snag my equipment on a buried stump or root. Root plowing is pretty hard to beat. I guess it is all in the application.
I built one several years ago for my Post Hole Digger, I had the same problem in that you had to move the tractor up as you lowered the drill,,I finally built a vertical slide unit that goes straight up and down,,,it worked great. Sold it in 1980 and never built another,,,wonder how long this one has been around.
This is a most awesome stump destroyer. I wonder why it spins counter-clockwise. Guess it doesn't matter. I like at the beginning where that one dude says "Okay -- I'll just move back a little!". That was funny. 'Cause he was scared.
@skgrek23 No. First of all, why would you want to. But the real reason is the angle of the PTO shaft. When it first starts out, the unit is so high in the air that the U-joint is past a 45 deg angle. If you put too much torque on that joint at that angle, you'd be changing U-joints all the time. And the whole purpose to this kind of stump grinder is the slow, safe speed. No chips flying all over the place.
Well, when I get the tens of thousands of dollars to get a tractor and this attachment, I may as well start hacking away at the stump with my axe - I know I could get the stump out before paying off that expense. Not to discount the pleasure gleamed form watching this stump get drilled. Very therapeutic for anybody who has had to manually remove stumps. Thanks!
That attachment is very cool, but when you need a used, $75,000 tractor to run it, it gets to be an expensive stump grinder....it does a hell of a job~!
u dont need to use a $75,000 tractor for that u can always buy cheaper second hand tractors that need a little love where i live u can have a tractor up too 160 hp for under 10,000 euro that work fine and look decent
Les Johnson LOL Don't you realize how many stumps there are to grind out there ? You see the machine grind 1 stump and you think that is all.Ha ha that machine has probably cleared 3000 stumps since this was posted ROFL !!!!
Usually the average production in 8 hours of work, plantation poplar trees, is about 600 stumps. Some customers say they destroy 1000 stumps a day, but better not to overdo it.
@rotorstumper Hehe, I agree. For minimum 140 PTO HP thats about $121,000. For the Stumper I say since the way it looks like its been built, maybe at least $12,000 for it. So them your spending $133,000 Minimum for it :D.
the best thing to do is to put a stick of dynamite.my uncle and father were doing that in the eighties. you had to choose a good shelter, though. but it was very effective.
Dude, I just spent all day drilling holes in the stump in the front yard so that I could use chemical stump remover. I had no idea anything like this existed.
Uhmmmm, what happens if the stump is bigger around than the auger blades. And does it have a reverse gear? As someone who has run a lot of post hole diggers, I can see this thing getting stuck bigger than hell.
Wow, what a beast! There have been a few times I wish I had this thing. I would think you'd need a bi-directional PTO in case you needed to back that thing out.
This is a machine designed to large plantations, where you have to remove 800-1000 stumps per day, 3-4 months a year. Is logical that not good for parks and gardens
@@FerriRotor no, not really, just that everything else works clockwise. Drills, faucets, nuts/bolts. The post hole digger on our bobcat (and every other one I've seen) goes clockwise.
@@dougnickerson7145 As I wrote the counterclockwise rotation, in this case, it is due only to the number of gears, and to their arrangement, present in the Rotor. It is not something desired.

If this type of device was used the hold could be properly refilled with soil and the lingering problem of "sink holes" would no longer be a factor. Conventional stump grinders cannot get the wood out this deep...it rots in passing years and leaves depressions in yards and fields.
great bit of kit !! it seems to take the stump down a lot lower than the rotating heavy wheel grinders .Thanks for posting.
This thing is amazing - Ive watched bunches of those saw blade style stump grinders, but this thing takes the cake hands down! Didnt take much more then a minute to dig it right to the ground
i find this unbelievably satisfying to watch.
I could do that job 24/7 and never get bored !
Not only did it grind the stump down...but it made some GREAT firewood that will burn great!!!.

Comparing to other stump removal machines displayed the most progresive solution. Would like to play with...

+bla blubb dammit i have a rose bush that needs to come out haha
It would take a pretty expensive big tractor to have the torque to do that.
Ferri Rotor ，
They never give the price because they don't want to be sued for causing hart attacks.
Of course it was demonstrated on a soft ash tree,but still an awesome machine never the less.I wonder if it has its own stand when not in use.
Very impressive.It might be expensive but it certainly does a much better job than the usual rapidly rotating other grinders which simply disperse dust all over the show.

wow this is so much better than those trailer stump grinders. they haev a vertical blade that grinds the stump little by little left and right.
One bad ass piece of equipment!
For some reason, I found this very satisfying to watch, also would've stopped the drill to collect clean kindling.
Neil Garret was thinking the exact same thing.

How much would you have to charge per stump and how many stumps would you have to remove just to break even between the two.
I have to say, this is truly a Thing of Beauty.
Nice but what do you do when you have a tough lie where you can't get a 6-9 ton tractor in?
that thing is awesome, i could use that all day
Best machine on the market for this task. Quick, clean, efficient. Why look elsewhere?
Great principle, I don't know how good it would be on large stumps? A bit big for the average garden!
This deeply pleasures me to watch this.
That was efficient and cool to watch
This is the best I ever seen. Have to check my piggy bank and see if I have enough change to buy one.
This is epic it makes me want one to just do this all day making my dirtbike trails lol!
@rotorstumper that is an expensive toy just for the odd stump you must be in landscaping?
Will this fit on my Snapper self propelled lawn mower?
Is there different sizes for different horsepower tractors? Is it a 3pth attachment?
Eight years later -are they still in business??????
Yes, stronger than before
Thankyou I needed to see what a stump grinder was as Ive been advised to hire one.
That attachment is very cool, but when you need a used, $75,000 tractor to run it, it gets to be an expensive stump grinder....it does a hell of a job~!
The world is big and there are contractors who perform this type of work all year round.
u dont need to use a $75,000 tractor for that u can always buy cheaper second hand tractors that need a little love where i live u can have a tractor up too 160 hp for under 10,000 euro that work fine and look decent

My dad bought an 8300 for $42,500. Put $20,000 in it for a remanufactured motor. The original had 10,200 hours.
Usually the average production in 8 hours of work, plantation poplar trees, is about 600 stumps.

I think you need a rather big tractor for this :) I would suck that the tractor starts spinning around the stump because it was to light :-)
Beauty, eh? But how does this thing work in rocky soil with large cobbles? The soil that came up was pretty clean.
do u need to sharpen the blades after a while ??
this is so cool, and better than the grinding machines!
This is strangely pleasing to watch.
Demolition always is. :)
Is the max hp so you don't destroy the accessory?
the best thing to do is to put a stick of dynamite.my uncle and father were doing that in the eighties. you had to choose a good shelter, though. but it was very effective.
Now that is some torque!

What would be considered the minimum sized JD tractor to run that Rotor S grinder?
+segarza 160 to 240 hp he said
+Jesse Cantrell okay thanks!
with a 160HP PTO you can do about anything, what can us guys with a little 30HP tractor use?

..plus an added bonus of kindling wood this winter!
now u just have a nice camp fire in that spot. and gone :)
wow now that is how it should be done, and you can even collect the wood and use is
So much better than those rotary head grinders and fling stuff everywhere and make a hole twice as big as the original stump....

How does it handle rocks embedded in the stump
That thing is freakin cool!
That thing is incredible!!!...but it sure takes the horsepower and torque to make it work...

Wow, what a beast! There have been a few times I wish I had this thing. I would think you'd need a bi-directional PTO in case you needed to back that thing out.
nice...now you need entire landscape crew to fill in the trenches the huge tractor made in the yard to get to and from the stump.....but very nice
@chakathewolf ,yes this model has the bi-directional PTO
Get in in there Morty!, All the way deep in there
That's awesome! really good idea

@sixstringfretter
In the new Rotor we apply a cardan double joints 75° for 240 HP
So what do you do on smaller diameter stumps that you can’t pull out or keep this thing centered on? I’m sure it sucks ass on smaller stumps.
very good stump cutter.
Good work Italy
O
Please explain - LOWER case keys ? ON a stump grinder
I dont understand what you mean by this John
WOW!! Now that's the way to remove a stump. Impressive. Safe.
How much does that attachment cost?!
Contact ferrirotor@libero.it
thanks for this. From where i can order it for my kobuta M110?
Yes,about 300-600 stumps
this is nice, no chips flying .
is it avaible in Canada how many rpm needed and how much?
seems faster n way cleaner. thumbs up
Knowing my luck, the auger would grab and start spinning the tractor around the stump. Haha.
that thing works pretty well!
I'm curious as to why they designed it to turn counter clockwise.
Perhaps because inside there are various gears.
But is there any rule concerning clockwise?
@@FerriRotor no, not really, just that everything else works clockwise. Drills, faucets, nuts/bolts. The post hole digger on our bobcat (and every other one I've seen) goes clockwise.
@@dougnickerson7145 As I wrote the counterclockwise rotation, in this case, it is due only to the number of gears, and to their arrangement, present in the Rotor.
It is not something desired.
The reason why the sense of clockwise rotation is universally recognized, on the right, probably lies in the functioning of the sundial
No high speed just pure power awesom
That job is a total grind.
I run an urban tree service, you must be out in the country somewhere- John
after you remove the old stump there is a nice place to plant a new tree
455 dislikes are from RUclipsrs who have posted videos claiming to have "The Fastest Way to Remove Tree Stumps".
The video you wrote was not posted by me.
Where did u buy that?
genius. That is the only way to go, right there
it must take a shitload of torque to cut through a stump like that
why dont you post a video of you getting rid of a stump
Wow...NICE! I use a little stumper. Short Stump with music
If this type of device was used the hold could be properly refilled with soil and the lingering problem of "sink holes" would no longer be a factor. Conventional stump grinders cannot get the wood out this deep...it rots in passing years and leaves depressions in yards and fields.
Looks a lot safer than a traditional stumper
