How does the chopping job compare between a chopping corn head and one with calmer chopping stalk rolls? Running a drago now thinking of going to a 2208 with calmer rolls or a case or possibly a Capella chopping head. Thanks

I do custom spraying for a guy who put calmers on his deere head last season. I was impressed with the job it did. Its still not the same as a chopping head for sizing every piece or cutting close to the ground but looked close to it. I have heard if you have rocks they are hard on the chopping heads. If you have rocks Calmer may be worth looking into. Not sure if this matters to you but this customer has a farm next to a chopping head field, the chopping field has drifts of husks in the fencelines and the calmer field does not because there is still some stalk sticking up to catch trash from blowing.

I put Calmer crushers on my 893 JD head last fall. I shelled 3 gearboxes in 900 acres. Had 2 gearboxes go out the last week of November, cost me 2 days that ended up being pretty valuable. Didn't finish the last 50 acres until March. One of the rolls on the broken gearbox broke apart, probably after the gears shelled, I was sort of hoping Calmer would stand behind it to some degree but they won't return my phone calls. I bought over $10,000 in parts from them.  I'm wishing I had gone a different route despite the fact that they do a nice job if you don't go to fast. One other problem I have had with them is the rolls grab and pull the stalk so aggressively that I have a lot of ears bouncing around. If I slow the head down to under 600 RPM is is better but then the stalks don't get crushed up as well.

Mind me asking what your were running it with and how fast were you pushing it? I'm considering them on an old JD643 but all i have to run is about 2-3 mph with them, pushing it with JD 7720. Thanks.

I put Calmer Choppers on an 893 last year and they did an excellent job. They really destroy the stalk from the snapping rolls up. I like the job better than the neighbor's 608 chopping head because it cuts too low for my preference. I couldn't tell that they used any more power on a 9660.

I was told that the older Deere heads had a gear in the gearbox that could go bad with the Calmer rolls.The newer heads the gear was welded? better in the gearbox.I think this was posted a year or so ago on here.

Haven't had any gearbox issues in 3 seasons on an 893. They will pull a little harder but don't seem to take a whole lot of hp away but will expose any weak links in the variable speed drive. For the first 2 ran it on a 9600 which worked fine but seemed to make the reverser run a bit hot. Now have a 9650 with hd reverser and cooler, runs nice and cool now.

They're not as good as a chopping head as far as sizing. But they beat any factory knife roll and can be retrofitted for a lot less than buying a chopping head.

Even Deere knife rolls on older heads will cause this. Replaced the cluster gear on 4 of 6 rows on a 1996 model 693 we bought new the season we upgraded to deere knife rolls. Went to a 2007 model 893 with calmer bt choppers the next season and no gear box trouble. Your JD dealer could tell you the year they changed the manufacturing process on the cluster gear. I think it was around 2004. We like our calmers BTW.

Maybe Calmer should make rolls for our Drago heads. Might be the cats meow, lol

If drago would do something to make them chop like others I wouldn't even think if switching but 2 foot long stalks in corn on corn are a pain in the butt

We put the bt choppers on two years ago and love them it is on a 643 and 6620 combine. After putting new rolls we were able to combine faster.

Chad did you get that hopper bought? Is your email good? i've really been thinking of putting those same rolls on our 643.

We have had both, have to say we prefer the chopping head. Possibly because with ND 100 bu corn we can combine at nearly 5mph. The Chalmers didn't do much more than regular rolls at that speed, while the chopping head works at any speed. Chalmers does great at 3mph or less.

No I didn't get that wet holding bin bought. I got talking with a friend that works at hendrixs and told me what all it took to to move the bin. He said if we couldn't get it bought for $1200 or less you couldn't justify moving it. It sold for $1500. I just changed to my current email

The calmer rolls do seem to cut down on trash intake quite a bit too which can help you combine a little faster as well. They really helped with walker loss when we had them on the 9600.

The Calmer BT Chopper is the newest stalk roll that will make your old corn head better than a chopping corn head. less moving parts, lower horsepower requirements, less money, etc... the CHOPPER stalk roll turns stalk residue into small "confetti like" residue. Stalks will be left at the height of the corn head, exploded top, helps keep residue from moving and is kinder to tires. No additional horsepower requirements.
The older Calmer BT Crusher crushed and crimped the stalk, leaving long 8-10 inch opened up residue. It was a great upgrade for its time, and was better than any other rolls available 2 years ago. These rolls are no longer available because we have gone strictly to offering the Calmer BT Chopper.
We have a 1 yr manufacturer’s warranty on all our products. If you have not been helped with a problem, please call again. We even have a trade program for your Crusher rolls to get Chopper rolls at a discounted price.
VERY IMPORTANT corn heads should always be as close to a 25° angle for best performance. Head speed is also very important. 55 RPM on gathering chain is a good starting point. If ground speed is 4mph, and chain spins @ 3, the lugs will back draft on the stalk and keep it from engaging the stalk roll correctly. Installation instructions on our web pages are a great read, even for non Calmer product owners.

To try it out installed 4 rows on a 8r22 40 series corn head, the two outside rows/side. Did a very good job-am planning to add the other 4 rows this summer-no gear box trouble but will redo the gear boxes with the heavier cluster gear. It is a 1980 year cornhead. The JD stalk rolls seem to push the corn ahead of the rolls at any speed but Calmers with the open window the corn plant comes into the middle of the rolls & chops the plant into 2" bits but leaves a 2' stalk less leaves but was very happy with what it did.
