Home made stump grinder

[Nick67GT]

@8ob That gear would've wrecked my lawn....

 

[brightspark]

if the cutting edges of chain are slightly blunt there a waste of time. u have to force them to cut and that generally puts wear on the bar and overworks the motor

 

[brightspark]

if u want to cut crappy materials and soil u need a disk with carbide teeth on they chew through anything

 

[slim_boy_fat]

I'd want a much more robust guard on it though, looks like it would kick back at every opportunity.

I repeat......

Nurse!!!

These are good, we have one in a petrol disc cutter http://www.ebay.co.uk/itm/TERRASAUR-BLADE-300MM-12-SLEEPER-TREE-STUMP-CUTTING-/250785320753
They can cope with soil and stones, as they dull off you just turn them around and go again, they somehow remain sharp. Take a bit of getting used too but are a handy bit of kit.

OP was thinking he could 'jerry rig' something with a brush cutter. Your link is for a 9" grinder/disc cutter which afaik require a firm hand and a stern voice.

[normspanners]

Wouldn't fit down my alley either....

I bet once it going it would make its way easily down your back alley

'Split personality' has just assumed a whole new definition.

I removed a sycamore around 15" dia. Got it virtually down to ground level. Then drilled a dozen 3/4" holes 8" deep and then filled the holes with genuine old creosote..Dead as a Dodo, roots and all.

Hmm, I do have a 9 inch grinder but £100....

Could I braze a load of carbide bits on a disk I wonder?

 

[pedrobedro]

My first job is to dig out the offending roots. There was a huge tree out there only yesterday which towered over the remaining part (which has a birds nest in it so is going to stay where it is). So I grab my grubbing mattock and er...

Well that won't do at all!
Clean

Sharp

Stake

Mattock heads aren't pinned, they lock themselves onto the taper as you use them, bump the shaft head on the floor to knock it on and the other end to take it back off. I take the head back off mine so it takes less room up. Best tool out for grubbing stumps out though.

Just don't go pouring illegal contaminates on it - penalties are servere

 

[Screwdriver]

If you need to pin or wedge a mattock or pick head, you've got the wrong handle.

I helped a mate with his shed/garden and my original mattock disappeared. This one I grabbed along with some other job lot stuff. I think the handle was too worn and compressed but still too good to replace. If you look closely, you can see I also had to bang in a wooden wedge.

Thermite ?

I had to do a bunch of them in my garden and got a kind of technique going. You want to get your self hold of an aldi/ebay 1 or 2 ton hand winch for about £15 and a reciprocating saw with a nice long blade. Use some tow straps to winch it tight to one side and it will reveal the roots, saw them and then keep winching and cutting as you feel the tension/roots. It's really simple once you get into the swing of it and probably easier and less mess to deal with than a grinder.

 

[Screwdriver]

Well before I worry too much about stumps, I do need to turn one or two trees into stumps first.

So I tied it off left and right then put some tension at the bottom. Plan was to drop the tree vertically, then drag the bottom out from under it. Did an angled cut with the chainsaw but the blades are dull so finished with a hand saw.

To my amazement, it actually worked!

Slight issue with the sharpened end digging into the soft soil but I just dragged it out, chopping it up as I went.

The stump system is HUGE though. There are/were half a dozen tall trees sprouting out from it. They are tall spindly things, at least 10 - 15 metres.

Looks like a nice spot you have there. Do you have much trouble with leaves in your gutters? well I suppose you'll be having less now!

Yeah your chain definitely needs a bit of a sharpen up - can tell by the dust instead of nice long shavings like you get with a sharp chain. I still sharpen chains by hand but I've been meaning to get a newfangled sharpening machine for years.

 

[Screwdriver]

It was pretty much taking a cut using friction. When the chain started smoking I figured that was the end of that!

If I can get rid of those stumps, it opens up the area a huge amount. Then I'll need to cart off about 3 cubic metres of dirt. No rush though...

Anybody want any dirt

 

[pedrobedro]

Sharpen that saw and make life easier, I'd have notched the bottom of those and finished them off with a push they are not much more than a stick
