L2 Straw Chopper Imbalance

So I can't get the salvage yard chopper on my old L2 balanced. Finally take apart to find the rotor tube has holes on both ends and of course is 1/2 full of dust. What's up with that ? Anyone know if these holes were supposed to be welded shut at the factory or plugged ?

Since this one shook apart the rest of the chopper, anyone have an old chopper for sale ?

Can't see the ends of mine while in the chopper. I don't feel holes but there is a spot on each end that might be a plug

We still have choppers, where are you located again? The closest I will get is MN or NW SD on 2 separate header hauls.

Our farm purchases a combine soley on its ability to do an excellent job in all of our crops, while being fuel efficient, reliable, ruggedly built, and easy to repair. That is why we choose a Gleaner.

L2 Chopper Balance

Sorry I missed your note in March ... I'm in Oklahoma and theres probably 20 L choppers within a 10 mile radius if you could see them through the weeds.

I power washed the inside of the chopper rotor tube until 10 lbs of dust and rust were removed, chucked it up in a lathe to verify it was straight, balanced it while chucked in the lathe, tapped those stupid open holes, dropped in a few BB's to polish the inside, installed bolts to seal out the dust, and reinstalled. Refined the balance after the rotor was mounted in the bearings it would operate with, carefully weighed the hammers, and installed them in like weight trio's.

So this year it ran smooth as a Gleaner can, the rear end didn't bob a bit. The heavy straw is a challenge and I just don't understand those blunt fixed chopper knives. I'd think cutting the straw would use less power than just tearing it over those blunt faces. Never had any luck in heavy straw chopping and spreading header width with this system.

Going to replace the blunt fixed knives with those goofy Crary sickle sections. Anyone ever tried this ?
