I have a small Sears chipper/shredder that will handle about a three inch diameter branch. I just re sharpened the (2) chipping blades to a 45 degree angle and now the thing seems very "grabby" when I feed in a branch. That is, it wants to yank the branch into the blades rather than letting me feed in the branch gradually so the motor (5hp) doesn't bog down.
The unit is old to the point that the blades have been sharpened several times over the years so I don't now what the official blade angle should be.
Any suggestions to make this thing less grabby?
