Chipper Can I shorten the chipper exhaust chute?

[Poacher Hater]

I have a champion chipper and it clogs more than I like. Would cutting off several inches of the chute where the chips fly out help? Seems the chips would fly out better and if clogged I could possibly unclog it without opening up the whole thing which is a major pain. I think my 35 hp Kubota is just a bit too weak to send the chips flying out and shortening the chute seems like a solution. Am I off on my thinking???

Your 35 HP may be a little on the light side, but according the their web-site your chipper is rated for tractors from 25 HP up to 60 HP. The Champion has the high speed rotor that should toss chip a long long ways. Are you running your tractor wide open? Has it done it since new, or has it recently just started to jamb? I know grinding a lot of green stuff can cause the wood not to chip so much as kind of bends it up. I know that can cause plugging as well. I guess what I am saying, is before I cut the chute shorter, I would do everything I could to diagnose why it is happening.

Totally agree. I have a two stage Valby I run off my 3710. rotor speed has nothing to do with clogging, unless you are REALLY slowing the rotor down. Green twigs and stringy stuff gets hung up on ANY edges in the exhause chute. For example where the rotor box meets the extended chute at the rotating joint. If the box tunnel is not aligned with the extended chute tunnel because of the degrees of rotation, stringy stuff will hang up and eventually clog up the chute.

I find technique helps. For example, run some green stringy stuff through, followed by fairly solid branches that make good solid chips. The heavy chips will often clear out the stringy stuff.

Chippers will clog, over revving the rotor is not the solution to the problem, nor is modifying the chute. Danger Will Robinson, DANGER!
