Chipper Chipper Blades

[dking]

How often would chipper blades need to be sharpened, roughly in hours? For that matter, how often would you have to replace the blades? These questions are assuming normal use and not feeding any wire or rebar thru the chipper...

I am curious on how you know about wire and rebar in a chipper? Or should I not ask?

haha - no I didn't feed any wire or rebar thru a chipper - just wondering how much 'normal' use before blades need to be sharpened.

Totally depends on what you are chipping. soft wood, hard wood, how much soil on it. Can be as often as every day or may be several months.

I watch the hour meter on my chipper and sharpen them around 40 hours. I have gone to 50-60 hours. That is getting a big too long as it is harder on the chipper. Also I rotate the anvil to have a good clean edge for the wood to be sheared when the knife comes down. Gap is another important thing.

On my manual feed Bearcat chipper/shredder I get 10 to 15 hours before it gets hard to push the wood through.

Mine was the same. After 10 - 15 hours of chipping the BearCat chipper would no longer feed the branches as well. I would then swap in my spare set.

dking,

I checked my log book and I had 40+ hours on the initial set. I will reverse them and send out when they are dull. Hopefully the new set will arrive next week.

10 or less usually. Whenever the chipper stops self feeding and starts "tearing" the wood instead of "shearing" the wood. Usually the bark starts peeling off the wood in strips too instead of being cut with the chips.

On my Morbark chipper I run around 10-20 hours on a set of knives before rotating.

I kind of keep a mental note on what I have been running through the chipper, and keep track of the hours via the hour meter.

Keeping the gap adjusted with respect to the anvil is also very important.

If I have even the slightest notion of any metal in the wood, I will set it aside for a burn pile.

It seems to me that a piece of rebar going through a chipper can get very expensive.
