Combines Spreading chaff

Yes with a rotary combine as much as half of the MOG going through the combine can end up on the shoe, so chaff spreading is important in most cases. I think your best bet would be to just buy a chaff spreader. Most of them are similar with one or two spinners driven by a hydraulic motor and powered by the reel drive circuit. Here is a link to Vittetoe. Another is Crary and I think there are a couple even made in Saskatchewan, like Kirby and another that escapes me. Redekop makes a chopper that processes both the chaff and straw, but they are a big spendy unit. REM used to make a pneumatic chaff spreader that used a pressure fan to spread the chaff, but the stopped making them. You can also lower your straw spreaders and make a tray to direct the chaff into the spreader. You should add the new cupped blades and speed up the spreader if you go that route.

I have 2 combines just like yours. On the one we put a Vittitoe axle mount chaff spreader on. It does a good job for the chaff coming off the seives. On the other 1460 we replaced the hex shafts on the original spreaders with some that are about 1 foot longer then original. We drills holes about every 2-3" so we could adjust the spreader up or down to where we thought it does the best job. By having one guy walking alongside the combine while operating we observed that the majority of the chaff that came from the rotor was towards the right hand side of the combine when standing behind it. Also a good bit of chaff was shooting inbetween the circular gap between the spreaders and leaving a small windrow on the ground. So on both combines I took a 6" piece of flat steel and bolted it to the rear of the combine just above the spreaders so that the chaff would be directed more downwards onto the spreaders instead of more rearward as it exited the combine. Doing that especially helped reduce and basically eliminate the windrow on the ground. As for the extended hex shaft on the spreaders, we only lowered the left spreader about 6" below the right spreader. The reason being, the left lower spreader catches a lOT of the chaff coming off of the seives and spreads it while the right spreader still running at it's original height spreads the residue coming from the rotor. So really I would suggest only exetnding the left hex shaft and leaving the right one as is. Give these things a try and I think it will certainly help your problem quite a bit. There are other option you can do but this is the least expensive way to start your experiment. IH also has a bolt on triangle shaped deflector kit available to put inside of the rear end of the combine to deflect the chaff onto the spreaders. Probably not a bad idea. Hope this helps!!

Buy the triangle shaped piece of metal from Case IH. They use on chopper equipped combines. then get the 3 new cupped shaped bats for each side. problem solved. That is what I did on my 1460.

does anyone have a part n for the triange shape piece you are describing, my parts people are clueless. Thanks

On a 1680 the deflector is 1319485C1 and the guard is 1321019C1. It says to only use them with the chopper. On a 2188 the same parts are recommended for the straw spreader and an additional deflector is used for the rotor discharge (staw and chaff spreader) 115497A1. I'm not sure exactly which parts are being recommended to you, and it's possible the 60 machine will take something smaller, but this should atleast get your parts guy something to look at.

Thanks for the help. It is greatly appreciated!!

You're very welcome...have a safe harvest.
