hello,

Is it a drum chipper?. If it is you need to make sure the angle of the blade or pitch is correct. What I mean is the angle it was sharpened . If this is worng it wont work as it is sopposed to. Also the cuttr bar needs to be adjusted correctly. There also is a plate before the drum( I dont know what it is called,) it can be wrong as well. Call Altec and ask to speak to a tech. They will sell you a manual. Hope it's an easy fix.

use a hacksaw blade to guage the blades between them and the cutter bar
Does it have a "drop plate" to enable stopping a feed? Check clearances.
If knives are set wrong distance out, or drop plate is wrong, the wood will pull past the drum and bottom out against the bed knife.
Kill the engine, stop the drum, and pull one of the branches out that did not feed. Look at the pattern of chipping. If it has a concave chipping groove that does not come to a point, something is set wrong.
That square, unchipped end is proof that it is not set right.

that will do it for sure.
Ok, you fixed the big problem, but..
Glad you caught the problem. I thought about suggesting that, but I didn't think that would be possible.
If you can miss that little detail, let me suggest that you probably need to work on some other details as well. It is very much like running a chainsaw. Even though you now have the chain on in the right direction, that doesn't mean it will perform as well as you can get.
1. Make sure that the blades are extended past the drum at the manufacturers recommended clearance. This is very important. Don't get this wrong!
2. Set the bed knife at the correct gap from all the knives, which are presumably all set at exactly the same level. Check EACH blade against the bed knife
3. Adjust the drop plate to the correct clearance after the knives are set correctly. Do this in the wrong order, and there will be problems.
