Woody material ( which is typically what people use chippers for ) isn't
going to improve the soil much by itself, you need to also add copious
amounts of green stuff, and it's better to compost it all in a pile first
rather than to simply till under.
In the absence of leafy greens, you can add high nitrogen fertilizer to the
pile but...
In the area I cleared for a vegie garden, I dumped about four pickup
loads of ground yard waste from the county yard waste disposal place
and followed that with about five pickup loads of horse manure. it
still is not great, but much better.
As far as home-owner grade...definately pass on anything that uses a
verticle shaft lawnmower type motor or you'll be sorry...
Those are pretty much useless except for shredding leaves.
RPM is increased via Vee belt appears to be 1 to 3 ratio so the main chipper
disc I would estimate runs ~2500 rpm, it is about 12 in diameter and has a
single tooth about 4in long located at about 10 inches along the diameter,
and is guaged to cut at a chipload of about .125 per revolution IIRC so
guessing it's probably processing at ~ 6000 or so sfm.
Do the chips go through the disk? I had a chipper that had either two
or four cutters mounted on a disk with slots in the disk that the
chips went through to get to the hammer mill section. Might have been
better with only one tooth. I moved across country and did not bring
it with me.
After that, the chips fall into what is basically a hammer mill, 4 rows of
with 6 flails each on a drum.... there is also a top hopper that you can use
to shove small dry sticks and green shubs and that kind of **** into...goes
directly to the hammermill...there is a screen under the hammermill that the
finished product falls out of....it's made from 1/4in steel and has ~1in
diameter holes drilled in a 1-1/2in grid pattern.
I might be able to get some pictures if your interested in the actual design
details but....
*--my main point is that it's still not quite as powerfull as I would
like--IIRC it will run 3in diameter green woody branches at a rate of about
5 ft/ min on a good day but at that size material frequently have to stop
feeding in order to keep the engine from bogging down and possibly
stalling.....
I could live with one that only chipped stuff up to an inch and a
half. I do not have much that is bigger than that and anything bigger
I can give to my neighbor that has a outside wood burning furnace.
FWIW, I have a fairly large burn pile I'm going to torch probably tomorrow
and pretty sure I haven't used the chipper in at least 5 years.
Can not burn here legally. Some of my neighbors do burn, but not big
piles and not often.
Oops--it's actually *a "mighty mac"...it's probably rated ~4 x 4 in--sorry
but at quick glance I din't see any model numbers.

Again, suggest first try the rental unit, ~40 horsepower......get er done

Good advice, but I am going to ignore it right now.
