I have about 15 uprooted stumps (courtesy hurricane Isabel) ranging in
size from 20-30" diameter. Many of them sank and shifted while the
tree fell and it does not appear they will "flop" back into their
hole...although I'm not sure since the trunks are still attached and
providing a counter-balance.
I am renting a Vermeer 252 (16" self-propelled) medium sized stump
grinder and was wondering if anyone has experience grinding uprooted
stumps and can lend some advice. Can I grind them while the stump is
horizontal? I think height is going to be an issue since the machine
is listed at 16" cutting height and the stump diameter is around 30".
The stump service I talked to sounded like he was going to use a
similar setup. I figure I could place some wood ramps to lift the
grinder...my backup plan is a medium-sized backhoe (JD 310) to dig out
around the stumps and flop them back in by force.
Advice from anyone with experience is much appreciated.
Perhaps, but I was told there are weight (10-20k lbs) limits on even the
largest dumpsters and I'm assuming the root balls weigh between 1-3,000
pounds, not to mention they are pretty large so it might take several loads
($400/load) which is a lot more than $150 for the grinder. I also figured
it would be difficult to lift and move these larger stumps with the backhoe.
I'll look into it.
No experience, so far. My trees are still all over the place, and not
as large. However...isn't stump-grinding usually performed to level
the ground and/or speed decay of the remaining portion after a tree
has been *cut*? Once the tree has been uprooted, this isn't the
problem -- just slicing it up and carting it away. I don't see much
evidence of post-hurricane stump-grinding around here except where
trees have snapped off. If the *trees* can be carved up, why not the
uprooted portion, too?
Stump-grinding, from what I've seen, more or less involves a
thoroughly-seated in-ground portion of tree treated to pretty vigorous
mechanical action. No matter how large the portion you want to get rid
of, it sounds dangerous to start boring into an unsecured portion.
As for hauling away, my city is engaged in picking up/disposing of
approx. 1M cubic yards of debris of all sorts. Of course, we have to
get it to the curb. :-)
It turns out it is difficult, but not impossible to move my stumps
with a backhoe (Cat 416). With the advice of the friendly transporter
fellow I removed as much of the dirt and roots as possible and was
able to hook the stump with the hoe. The second one was smaller so I
didn't bother to knock as much dirt off. When I picked it up the
machine was very "light" on the front wheels. I cautiously crept
forward, but the slight incline was too much and back she went
(probably less than 2'). Pretty intense, but man is it fun to dig!
