Post your stump grinding photos

Today, one of 5 mixed conifer stumps. A Picea stump after I'd cleared the soil with mattock and blower.

4.8hrs machine time today plus prep. 5 hours being my limit of endurance especially when the weather is in the high 20's.

The Picea wood was reasonable soft and the B20 flew through it.

I ground a cedar down to 40cm+ by digging a slope.

A windblown picea was a fecking mess of tangled roots but succombed in the end.

A couple of pines tested my patience with their dense fibrous cores.

Tomorrow I tackle a large Douglas (130cm)

I've already nibbled at some of the surface roots up to the stump.

Different proposition, very tough and fibrous.

Once I've chased the surface roots I'll turn the teeth.

The QRMS teeth are less sharp than the Greenteeth which causes me to think of getting a stock for just such occasions.

I used to change to Red Teeth for conifer on decent soils, much faster.

Anyone know if these still exist?

That is the stuff of nightmares.

 

Do you chase the roots first then, once they’re all done, attack the stump?

Here is my new toy. Old multi tip wheel from my now dead Huxley's Little David, metal frame/chassis built by fabricator friend, Honda 20hp engine. Works well, just waiting to get a minor niggle on the digger hydraulics sorted - after not moving the boom for 20 seconds or so there is a long pause till it responds again, and I can't react fast  enough to prevent the  grinder wheel jamming and belt squealing. Digger only had 22 hours on it, and dealer going to sort it out.

Grinding from the top downwards is hard. 
 

 

There was a guy on here with a massive engine/grinder set up like that.

It was awesome.

Could be one of them little electrical things controlling the hydraulic that is loose. Check it.

Yes, but as only 22 hrs on clock and under warranty I will leave the dealers to sort it.

Not as hard as grinding from underneath the roots upwards!

I'm guessing you mean try and keep the grinder working on the side more than on the top?

Yes

Exactly, you get better ‘breakaway’ of material because of the way the growth rings and radial lines are ‘constructed’

Overuse of inverted commas I know, if anyone can find an alternative for constructed, I’d be grateful.

I do.

Profiting from the dry weather, I scratched around the roots and used the blower to remove the soil.

The Douglas I am currently chewing my way through is proving to be a tough nut.

It is 3x the length of my mattock.

The roots are hard, producing long fibres.

I'll turn the teeth again after lunch, gallette with clients homemade cidre.

I would try to find a subby with a bigger machine tbh.

 

 

Sisyphean comes to mind.

Debris screens came in handy for some shade for the dogs.
