I was at an estate sale yesterday and wound up with an 18" Craftsman
"shredder/bagger" that seems to run fine, though its not been fired up
for at least 10 yrs or more. (Got quite a number of other goodies as
well..but nothing Im having any problems with)

http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Grass-catcher-Parts/Model-917270010/0247/1500115



Question #1
Is a shredder supposed to have sharp blades like a chipper or do they
simply bash the vegitation to bits and spit it out?
IE:
Is this beasty supposed to have sharp blades?
Or are they simply beaters?

If so, what angle and method is best to sharpen them?

I ran part of a tree limb through it and it didnt want to shred it very
well. Some of the smaller branches kinda sorta got shredded and chuffed
out, so Ive got the idea of how its supposed to work...chuckle but I
cant find a manual for it so dont know "whats too big" and "how to get
gnarly branches to go though the blades" and so forth

Any info would be greatly appreciated, on service, lubrication and so
forth. Im currently searching for a manual, but am not having a lot of
luck.

You're never going to keep them "Scary Sharp" for long, but they
should have a little edge to them, just like your lawnmower. Cutting
is always going to be more efficient than beating the branches into
submission.

I'd get out the 4" angle grinder and just touch up the edges at the
same angles it has now. And like a chisel, don't touch the flat side,
only the cutting edge.

SOP - If it has bearings, grease them. If a shaft pivots, oil it.

If the branch hopper has a 2" opening, that probably means they don't
want you shoving 6" limbs through it.

I'd suspect they are suppose to be sharp. Heck, even reel mowers
were sharp.

Hmmm, I wonder how this would do for grinding up chickens - bones
and all? I make my own cat food (cheaper than store bought) but
grinding them up with a Universal #2 is a tedious task.

Go not to the Net for answers, for it will tell you Yes and no. And
you are a bloody fool, only an ignorant cretin would even ask the
question, forty two, 47, the second door, and how many blonde lawyers
does it take to change a lightbulb.

Shredders are not chippers as they don't have an anvil for the blade
to shear the branch against. My old shredder had problems with anything
much bigger in diameter than a pencil. Shredders do a wonderful job at
reducing the volume of leaves and chopping up compost and twigs but
not much more.

Yes, I believe shredder/baggers are intended for leaves. And if you have a
lot of them forget it.

My old 1 cylinder flywheel (what an engine) Chipper/Shreader
had two shoots. One big one for junk like leaves. Thrash them
to nothing. The chipper was a shoot on the side - and it was
for 3" or less. 1/2" would jam in it and require a thrashing
by a good limb in the shoot.

Looks like you have a high speed cutter and two flying blades
that inflate the bag to stuff it with junk. Not really cutting
but last chance.

Yes, again. I have that machine with a vertical 5(?)hp gas engine. It
does a nice job of shredding leaves (if I'm VERY careful about not
letting them jam in the chute). The blades do not need to be sharp for
leaves.
