What's the logic?

flying belgian · Dec 14, 2019

I'm replacing the gathering chains on corn head. Is there any logic as to weather you put the tabs across from each other or stagger them? I've looked at heads sitting at dealer and
pictures of heads on tractor house. Looks like they have them both ways and every conceivable way possible. There appears to be no standard. How ever they end up, they just run with it.

When I was in college going thru the deere program we set a 6 row with half each way. We never did notice and difference. The chains on my corn heads are all staggering.

Also my Cressoni head has stops on the spring loaded idler pully of the gathering chains. No other brand has stops. What would be the purpose of that? and where would you set the stop? I have the parts manual but not an operators manual.

Everyone I've worked on were staggered.

IIRC the Deere manual says to set them opposite each other if you need more aggressive action. Under normal conditions run them staggered. Also the Deere head has a tube around the spring that serves as a stop on the tension spring. Tighten the spring till there is about a quarter inch gap between the washer and the tube. It allows the tensioner to flex but not enough to let the chain jump off the sprocket.

If your corn is down run them across from each other for it will feed in better.---Tee

My Gleaner manual said to set them staggered.

In real life, one or the other will run the slip clutch now and then and they will come out however they come out for the next hour, I see no difference in the real world some will be staggered some will be across and it will change by the next day on its own.

Many years ago while an apprentice mechanic, I was sent out to replace some bronze bushings on a New Idea pull type snapper. I tried to make the farmer think I had much experience and told him that setting then exactly in the center of the other chain. After I thought I had convinced him that I was an "EXPERT", his reply was why thee was a slip clutch on one sprocket. He guessed that this was my first picker repair and we always got along well.

I always start them staggered though I don't think it matters. I do flip them to be opposite, so they can wear on the top side down . The rollers and pins last longer that way. And NI used to have stops with the end of the slotted holes holding the front idler. If the chain got to loose and it got pushed back it could come off. I think dads old square link chain cornhead for his Gleaner E had the slotted holes for the stops also. Been a lot of years since I looked at it.
