Rock Chuck, thanks for the info. That's what I'm hearing from several reviews of almost all of the smaller chippers, that they don't take anything but small straight limbs, not crooked, limby fruit tree ones. I don't want to buy a big commerical chipper.

I looked at a Craftsman 3" chipper today of almost identical design to yours, only painted red and with a slightly smaller engine, 250 cc. No manual with it. I assume that the smaller angled chute is for big branches, or do they go in the top hopper? I would limit mine to one inch diameter stuff rather than try to chip 3" limbs.
