2013 bandit 75xp bad jamming problem behind feeding wheel

I have this one with the original 25 hp engine. Been working well till a few days ago. Some wood chunk goes behind the feeding wheel and end up vertically jammed into the space between feeding wheel and the chipper body sheet metal. The sheet metal is not that heavy so it got pushed out more and makes it even more vulnerable to happen again after clear it out.

I can’t understand why this would happen. The clearance between feeding wheel and the surrounding body metal should be small enough not to allow the to happen.

It got so bad yesterday finishing up some small stuff. It James almost every 10 min, even small long honey suckle stuff.

Anyone have experience with this and know a solution? Thx. Erwin
 
If you have checked the knives and they are ok, slow the feed wheel speed on stringy shrub materials. I push knives past dull and a couple hundred bucks for a new set usually fixes my troubles
 
The chipper had been working the way it should, not nearly as powerful as the other 6” bandit I have that I put a 40hp Kohler, but good reliable one.

It just happened a few days ago, checked knifes and anvil. They’re all in good shape. Again it jams all the time and it’s very hard to get the jammed wood out since it’s wedged there.

An observation might be related to this. The front end of the feeding valve is leaking out fluid, not too much. Don’t know if the jamming causes pressure to go up and cause leak or the valve is causing the jamming.
 
Low pressure will cause auto feed function to not work. Sounds like it is feeding faster than it can chip. Full stems of old shrubs are super dense
 
I own a 75xp as well and struggle with the exact same issue. On my machine it is somewhat species dependant and is most consistently an issue when chipping deadwood. I have yet to find a "silver bullet" but I absolutely do notice that the issue recedes when I swap to fresh knives, though it still can jam in the way you describe with brand new edges.

I believe that there is too much space behind the infeed roller and have thought about having some flat steel plate welded in that box to narrow it slightly, maybe even 1/4" plate would do it; haven't pulled the trigger on it though. If I do and it fixes the issue, I'll let you know and share pics.

I’ve been thinking about the same fix. Let me know when u get to it. Have a brand new set of knifes now. Will see.
