Home Made Stump Grinder

[rayfalcon777]

I have worked on and even Built complete riding Lawn mowers and service Lots of outdoor equiptment like this can you send me the plans and parts list you used heres my addy speedjunky at windstream dot .net No spaces in case it blocks it. They made me do it long form Lol

[sakahowdah]

Goes like a raped ape. Good job..!

[rdorrel]

Thanks Sam. I was able to find a heavy round part for the flywheel. I purchased used carbide teeth from Ebay which were dull. I sharpened them and machined some holders to bolt to the flywheel. I believe the radius of the teeth is about 19" and I run it at about 4000 SF.

Hope this helps.

[samafrench]

Thank you for posting a video. NICE setup. What did you use for the grinding wheel? I am guessing it is 16 in diameter. Is it running close to 1000 rpm? Thanks again Sam.

[peteacher52]

All good. I was going to say something about a face guard against the rogue chip that finds its way to your tender parts, but I see you've got that well in mind. Very efficient use of equipment you already have. Good thinking.

[TheRottybear]

Now that's cool!

[Clawedbackster]

Looks like it works good. Good job.

[Dookiedolf]

Looks like a debris/shrapnel disaster waiting to happen.

[KrashKrazyKash]

Sweet, nice work on the build..

[lethallarry1]

Seems to work very well. Good job!

[rdorrel]

@lethallarry1 Thanks!

[BrokenRRT]

Do yoursef a favor and place a pc of plexiglass infront of you.

[theBLC420]

A message for all the posters hating on this guy's safety skillz: Can't you see the shroud?? I mean sure, it's made from bent-up, light gauge sheet-metal or maybe some type of plastic, but obviously it's enough to stop flying debris....this man is a genius, and nothing could possibly go wrong here. KUDOS TO YOU, SIR!!!! What an AMAZING invention! Fuck renting a so-called "safe" and "efficient" machine for only a small amount of money...what kind of PUSSY would want to be "safe" and "economical"?

[tibuflavius]

if i would have a chainsaw,a shovel

i would done it faster ,better, cheaper,

not desturbing animals

sorry for bad english ,i salute from romania

[rdorrel]

@tibuflavius Thanks.  Hope everything is good in Romania!

[richiewrench]

@tibuflavius I look forward for you're video of you doing this faster with a chainsaw and shovel!

[shooterm24sniper]

What did you use for the cutting teeth

[rdorrel]

@shooterm24sniper The teeth are 1/2 square shanks with carbide tips.

[huntlone]

how fast is the cutter blade turning is it chain driven or direct drive

[rdorrel]

@huntlone I designed it to run around 4000 SFM. It is direct drive. 

[mikedavis5671]

Great job...Patent it quick!

[rdorrel]

@mikedavis5671 Thanks.  Although I wouldn't mind building more I have no interest in dealing with the lawyers the sue happy public would bring with them.

[MrWonkawonka69]

im impressed...good job sir.

[urbex2007]

That is a really good idea I like it when people think about a problem and work at a solution. That is ideal for the job.

[rdorrel]

@urbex2007 Thanks. I appreciate your comment.

[deanjohnwoods]

You dead now tree...say uncle

[rdorrel]

Thanks for your kind words.  I believe common sense is the best first step

when it comes to safety.

[Michaelneil17]

Beautiful job ,  nice guard on there, I think you have the safety covered.

I like the smooth pace in cutting, some people think safety as they are working as you obviously do. Some people depend on safety devices to keep them safe.

and don't think about technique. Again, great job !

[sanekx107]

It reminds me grindcore.

[arnoldcustom]

i made same years ago and still make lots of cash with with it, good show

[rdorrel]

@arnoldcustom Good deal. Maybe when I retire I can use it more.

[geneticrabbit]

nice job i want one!!!

[rdorrel]

@geneticrabbit Thanks for your comment. It's not that hard to build. Go for it.

[zeppelin67637]

blendtec has met its match. Thats just fucking evil.

[murphy4trees]

looks like you hd fun with the project... still would have been cheaper to renta a grinder.. you could ground all 40 stumos in a day for $2-300.. and wear eye protection and a hard hat when running that.. You should really have a door to protect you... If you can see the grinding, you are in harms way!

[rdorrel]

@murphy4trees Didn't build it to save money. Anyway I have less than $300 in it.

And I will always have it. I have ground many stumps for friends.

Sorry you don't approve of the way I run things. I always wear a face shield just not for the short video.

[murphy4trees]

@rdorrel its all good.. just lookin out for you.. More power to you for getting it done that cheap.. nice to have tools in the aersenal

[ffjsb]

@rdorrel I have to agree with Murphy on safety (except the cost thing, sometimes it's nice to know you just have the know how to build something) You should make a door or barrier out of some heavy mesh, that with your face shield would do the trick I think. If you can built this grinder, a safety shield should be no problem for you. Is there some kind of relief valve for the hydralics in case you hit a rock or pipe? Nice machine.

[coldnapalmFJ]

@murphy4trees even if you can see it through 2 foot thick bullet proof glass?

[illymozar]

Nice piece of equipment you made. Though I think you should have some type of enclosed protection for yourself in case something goes wrong or flying debris

[junekentucky]

Got any pics of it not moving? Brother could probably build one of these but I want to see how you made the head.

[rdorrel]

@junekentucky Sorry I don't have any still pictures.  Thanks for asking.

[Urakoitsija1]

Very powerfull and vice machine ! Thumbs up;)

[rdorrel]

@Urakoitsija1 Thanks!!

[rdorrel]

@Urakoitsija1 Thanks. I appreciate your comment.

[rdorrel]

Drill a hole,  Poor black powder in at $16.00 per pound, pack it in, light a fuse and run. When it blows you still have a mess to clean up and a hole to fill. In Three minutes I am ready to move to the next stump.

[thibautthirion]

tronçonneuse et ça va aussi vite.... et la machine est moins chère

[falconxample]

Peut être mais tu ne peux pas poser ton cul confortablement, tu ne connais pas les us ? ;-)

[ixamraxi]

Why not just blow it up?

[goglesux]

man,ust grab a funken chainsaw and cut it down to the ground, lol.

[jijvoormijn]

so dum

,dit is echt zo dom wat gebeurt er al hij grip heegt , e?

1 de arm slaat om en waar naar toe,? ook zal het wiel frees niet stopen met draaien,

of heel traktor valt om veilig heid kenen ze daar niet

[raticide4you]

Interesting! Never seen a thing like this. Lots of respect for your work..

[savagenomore]

sure beats the hell out of that one I had to rent from Home Depot.....

[mtlassen1992]

And when the carbide breaks or wears out, get yourself an Acetylene torch, some silver solder, and retip them yourself! Its very easy. You can also get cheap diamond wheels on ebay, and rig up a water sprayer to cool as you grind them. Just remember, its not rocket science!

[thegenrl]

do you have more info or still pictures of this? it looks great! id love to make one a similar one (but smaller)

[Libelya]

compliments! it work very well:)

[bornsk8ing]

lol 2:04 it goes on a spaz

[hand6969]

this is a very amazing machine you made! i would love to make one just like it for the farm but i have a few questions? did u bolt the motor shaft straight to the cutter wheel and what did u make the cutter wheel out of, and what did u use for the bearings? it looked like a bearing cap but could not tell. thanks

[fangus503]

Go faster.

[managedassets2009]

The hydraulic system has a relief valve which keeps the pressures from

exceeding the components maximum operating pressures.

[UBERKron]

nice machine. what governs the hydraulic force?

[andrewwoodside]

Doctor says: "What happened THIS TIME?"

Patient says: " I made a Homemade Stump Grinder"

LOL.

[MrTpengineer]

@andrewwoodside And the ironic thing is that he grinded his own stump lolz :)

[notoriouslizw]

Excellent! Made my morning and I don't even need one! (right now...)

[gunplow]

turn the drum vertical

[g9csr]

show us the cutter statically!, and tell us what was done to create it!

[500passwords]

nice job , works good .

[rdorrel]

@500passwords Thanks. I appreciate your comment. I used it again yesterday.

[amerknowhow]

@rdorrel

I like your invention. How do we talk off line?

[beyondupnorth]

The biggest issue I see is you need flat ground underneath the loader so the operator can control the cutter height.

It is working good in the video but most places I grind are not that flat and smooth and moving the loader would cause some bounce that would stuff the cutting wheel into the stump.

[th19940305]

how much did it cost to make?

[poptart1702]

Where did you get the cutting wheel and teeth from? I would like to build a pto driven stump grinder but the replacement plates from companies like Vermeer are expensive.

[rdorrel]

@poptart1702 I bought some used 1/2 square carbide cutters on ebay and sharpened them. I was too cheap to buy new ones. Sharpened ones work just as good. I machined the holders. New ones are available on ebay but once again I was too cheap to buy them.

[oldstumpcutter]

Bitchin machine! Did this require high flow?

[rdorrel]

@oldstumpcutter Sorry for the delayed response. It did not require a lot of flow. I used the standard auxillary pump which creates 16 GPM. Thanks for your comment.

[bearbon2]

Nicely done! Judging by the smooth technique it looks like you've done this a few times.

[Hazardflag02]

AWESOME!!!

[partyboy1800]

pretty cool. you do know for like 5 bucks you can buy a pound of powderd stump remover and it will be gone in a week and whatever is left over can be used to make a bomb

[Wallabydam]

great work, nothing like the satisfaction of making something yourself to do the job where most people have to pay big money for it, good job!

[rdorrel]

Thanks for your kind words. You are right. It is very satisfying to build your own tools.

[windchill8]

what did you use for teeth?

[rdorrel]

Sorry for the late reply. I used cemented carbide 1/2" square teeth.

[pigwerks]

What size orbital motor for the drive?

[rdorrel]

Sorry for the late reply. The motor is 2.573 cubic inches.

[radicaldanzero]

Awesome job!

[rdorrel]

Thanks. I appreciate your comments.
