John Deere 8100 and Rotor S stump grinder

[@randymiller3949]

Not only did it grind the stump down...but it made some GREAT firewood that will burn great!!!.

[@LCHLLO2008]

great bit of kit !! it seems to take the stump down a lot lower than the rotating heavy wheel grinders .Thanks for posting.

[@WowMike2002]

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

[@mooreconor]

i find this unbelievably satisfying to watch.

[@karjack11]

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.

[@doclee8755]

If I ever need a stump ground up, this is the only way to do it...legally. That was pretty cool!

[@nexxtech911]

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.

[@Squarerig]

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.

[@FerriRotor]

Thanks

[@Wildstar40]

I could do that job 24/7 and never get bored !

[@sixstringfretter]

@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

[@MilanDupal]

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

[@publicskeleton]

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!

[@AntoTheAvgeek]

I have to say, this is truly a Thing of Beauty.

[@perltech]

Wow, this is one bad-ass machine, and safe too.

[@AceTreeManagement]

nice job ! is that as fast as it can go ?

[@sixstringfretter]

@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.

[@Shane-Singleton]

Depending on the type of tree that thing could be churning out some really good grill/smoker fuel.

[@johnrochester3551]

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 is the best I ever seen. Have to check my piggy bank and see if I have enough change to buy one.

[@jimritzheimer7465]

that thing is awesome, i could use that all day

[@utubeisamess]

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.

[@TheTexn]

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.

[@jurgenfiehler8246]

Prima, und was machst du mit einer Pappel oder einem morschen Szumpf

[@HisWayFarm]

@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.

[@lytken]

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

[@FerriRotor]

+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 [e-mail] specifying the request with the data of the tractor.

[@MrSkoobii666]

+bla blubb dammit i have a rose bush that needs to come out haha

[@brucec43]

It would take a pretty expensive big tractor to have the torque to do that.

[@hieutran6121]

[@michaelschettl9509]

They never give the price because they don't want to be sued for causing hart attacks.

[@Saki630]

this is so cool, and better than the grinding machines!

[@BigMacD1442]

This deeply pleasures me to watch this.

[@gaterunner64]

For some reason, I found this very satisfying to watch, also would've stopped the drill to collect clean kindling.

This is epic it makes me want one to just do this all day making my dirtbike trails lol!

[@localcrew]

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.

[@OlfArts]

Thankyou I needed to see what a stump grinder was as Ive been advised to hire one.

[@CoryHollister]

Now that's how you grind a stump, that John Deere made light work of that

[@DesertDigger1]

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.

[@AceTreeManagement]

What size tractor do you need? Cheers Ace

[@lesjohnson7663]

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~!

[@FerriRotor]

The world is big and there are contractors who perform this type of work all year round.

[@jwvanliere]

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

[@Wildstar40]

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 !!!!

[@Kllrkrtt309]

My dad bought an 8300 for $42,500. Put $20,000 in it for a remanufactured motor. The original had 10,200 hours.

[@FerriRotor]

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.

[@stevestinnett5642]

Will this fit on my Snapper self propelled lawn mower?

[@rocintrucker83021227]

Nice but what do you do when you have a tough lie where you can't get a 6-9 ton tractor in?

[@Hermanvogel]

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.

[@Stjepan105]

No high speed just pure power awesom

[@annehaight9963]

This is strangely pleasing to watch.

[@georgeboyd2774]

Demolition always is. :)

[@fiskeman92]

Damn thats alot of stumps before sharpening :) Is the rotorstumper availble in norway ??

[@thedungeon1288]

Now that is some torque!

[@kenlelon369]

genius. That is the only way to go, right there

[@pdoggy10inch]

That thing is incredible!!!...but it sure takes the horsepower and torque to make it work...

[@lytken]

wow now that is how it should be done, and you can even collect the wood and use is

[@martianshoes]

So much better than those rotary head grinders and fling stuff everywhere and make a hole twice as big as the original stump....

[@erniecasarez6904]

[@fernandotorres295]

seems faster n way cleaner. thumbs up

[@MisterWillie060]

Is the max hp so you don't destroy the accessory?

[@fiskeman92]

do u need to sharpen the blades after a while ??

[@ddavid122]

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.

[@randomvideowatcher]

That job is a total grind.

[@deathcar]

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.

[@FerriRotor]

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

[@ShippingHarbors]

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 :-)

[@TR6RRod]

WOW!! Now that's the way to remove a stump. Impressive. Safe.

[@American_Made]

That thing is freakin cool!

[@oaksap]

How does it handle rocks embedded in the stump

[@cnman9743]

Is there different sizes for different horsepower tractors? Is it a 3pth attachment?

[@bugbomb8048]

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

[@boardingpass04]

@rotorstumper that is an expensive toy just for the odd stump you must be in landscaping?

[@george8873]

455 dislikes are from KZbinrs who have posted videos claiming to have "The Fastest Way to Remove Tree Stumps".

..plus an added bonus of kindling wood this winter!

[@pedrov9185]

Looks a lot safer than a traditional stumper

[@FerriRotor]

Yes,about 300-600 stumps

[@ravenwind123]

after you remove the old stump there is a nice place to plant a new tree

[@GardenEquipmentReview]

Great principle, I don't know how good it would be on large stumps? A bit big for the average garden!

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.

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.
