Just broke both feeder chains" 3rd broken feeder chain in soys this year" on our new 7010 with 2162 draper head. Our previous combines 2388 seemed to slip the clutch and then the electric shutoff would seem to stop the feeder before it did much more than maybe bend a slat We broke only one feeder in 20 years on the previous combines. Maybe just bad luck this year or maybe it cannot stand stones as good. The stones were about 6 inch and both ended up past the drum but not in the trap. After the first break we did tie the feeder and run the slip clutch ten times like the manual suggests but it didn't seem to solve the problem Has anyone else had this problem and know of an answer other than picking every stone We do use a packer.

Have you had your dealership remove the gearbox and test the torque on the slip clutch? That is good place to start, some of those slip clutchs come way too tight. Like you say it should slip before it breaks the chain.

we broke one with a rock and were able to fix it, but three days later another rock and this time we cut it off the rotor transition. luckily the dealer had got two in after the first problem and we just had to go get it when we needed it. The only one they could get was for no rock trap so we had to shorten it a bit the other one is still just fine both times it got the left one.

Ran several rocks through mine. Bent some feeder bars. Too much power and not enough slip. Rock trap doesn't work as good as 2388. I roll all mine but pick up a rock sometimes going through drainage ditches. Also run a 2162. Like it ! KAD
