I do a LOT of sawing outside in the cold, pruning apple trees. I've been
using a 24 volt Dewalt sawsall. Battery life is terrible and getting worse
as they age.

I'm thing of trying a pneumatic sawsall or sabre saw. I found this one:

Chicago Pneumatic 881 - Saw Air Reciprocating Heavy Duty


Anyone know anything about these units, or can recommend a better one? Do
they take the standard sawsall blades?

For pruning an apple orchard? Ya, get a small gas chainsaw, and a good pair
of pruning shears.

^^^^^^^^^^^^^^^^^
Probably good advice. The question about a pneumatic Saws-all is air
supply. A moderate size portable tank will probably give you less run time
than the batteries. You will need a gasoline powered air compressor. Or,
how about putting two 12v car batteries in series, and cobbling up a
connection to your electric saw?

That's what I was thinking.
I call for a vote: Raise your hand if you think he should use car batteries.

Those type of air saws are generally ued on thin sheet metal bodywork.
You might not be able to get a blade to fit your application. Plus
having a compressor and dragging an air line around is going to slow
things down quite a bit, and getting caught in the trees. I did a quick
google and came up with a couple of items, one battery powered, one gas
powered and one electric(would need a small generator if plugs are not
around). Hope this helps

I maybe should elaborate a bit. I prune 30 hours a week with a two or three
man crew. Mostly with air power pruning shears run off a portable air
compressor on the tractor.

Large cuts are done with a small chain saw. I go through ahead of the main
crew and make the major cuts.

About once every five trees there is a branch a bit too big for the shear.
Its very handy to just gab the sawsall. The 24 volt electric is not quite up
to the task.

Seems to me that it would be possible to have an air power saw.

I have an import version of that. It doesn't have nearly the power of
an electric one and it stalls easily. A more expensive one like the
one you show might work better -- but I would think that an air line
would be a lot heavier to drag around than an extension cord even
though the tool itself weighs less than an electric one.

Milwaukee has a new line of cordless tools called V28 that use
28-volt Lithium Ion batteries. They are claimed to last twice as
long while being considerably lighter in weight -- but they are
pricey. List is $755 but I see them online for about $360. Extra
batteries are about $125.

I have a compound-action bypass lopper that easily lops off branches
up to about 1-1/2" dia. The brand is Corona.

They claim up to 2". Maybe, but that might be a struggle. 1-1/2"
branches are easy.

A small lightweight chainsaw makes quick work of thicker branches. I
have a little Stihl that I like a lot because it starts and runs very
reliably. If I did a lot of chainsaw work I'd probably invest in an
Husqy.

Don't know if it's still the case but Florida Power and Light used to (40
years ago) use pneumatic chainsaws for trimming trees that were in danger
of contacting power lines. Don't know if they did this for safety reasons
or if the pneumatic saws were more reliable than electric or what.

If you google "pneumatic chainsaw" you'll get a number of hits including
some on sources that have other pneumatic and hydraulic tools for tree
pruning and related tasks.

We had hydraulic fittings on one of our bucket trucks for hydraulic
chainsaws.

20+ years ago, our 62 year old secretary, who lived in the country and
had a backup 3kw generator to operate their sump pump during power
outages, wanted to prune trees on her ten acre "estate". She took me
up on my suggestion and borrowed my electric chain saw, put the
generator on the trailer behind the riding mower and climbed around in
the trees sawing off selected branches as she went. Just wish I had
been there to take a few pictures to prove that such things do happen
in real life.

5/8" stroke, looks long enough to drive a 6/8 TPI wood blade. And I-R
doesn't make junk.

Can your tractor-mounted compressor deliver 21 CFM, Karl?

^^^^^^^^^^^^^^^^^^
Probably not necessary, since a person climbing in trees with a saw is going
to have a low duty cycle. It's only necessary to have a tank large enough
to get you through each cut. (And a hose large enough to deliver 21 CFM.)

The compressor is big enough, but my wallet isn't. $2100 for one of these.

I'm buying a $375 version from MSC. If it don't work out, I'll have another
shop toy.

I have that Stihl saw and it really Rocks! - it is intended to be an arborist jr.
saw - as the model it was based on it like triple the cost. 6.6 pounds :-)

I got it to do overhead work on Hurricane trees (new species now) - and I cut not only
limbs but trunks. Starts on one or two pulls and tires me out before the tank is.

I also have a Husky 50 20" bar - and it is good on the big stuff but is heavy to whiled.
