Combines specialty rotor

We are running a spec rotor in a 1688 growing wheat, seed beans, and food grade white corn...large wire concaves, all wires are in, no covers on concaves, keystock grates...an airfoil chaffer helps simplify things but you can make what you have work very well for you. ran a 1460 standard rotor for several years, so far I have found nothing negative about the spec rotor. feel free to email anytime if you need more info.

You will find that the speciality rotor tends to have a little more rotor loss in wheat and more cob breakage in corn. Definitely a plus for todays green stemmed beans. Go with the 80 size you'll never regret it. Update the fan to the new style too.

The specility rotor was made for rice. It was made for easy to thrash but hard to feed crops. The conventional rotor is a better thrashing rotor because it has more bar to concave contact. The specility rotor was introduced into the corn and bean areas because of the green stem beans. Not corn. The reason it is better in the beans is because it is more agressive. It is also more agressive in corn as well but that wasn't needed. The problem with the more agression in corn is rotor loss. There are severial things that can be done to a conventional rotor that will make it as good in beans as it is in corn. I would be happy to visit to any of you out there about this subject. Call me any time. Ask for Don @ Estes Mfg. Co. 1-800-235-4461.

I haven't been around the speciality rotor buch, but I'd think it tears the straw up even more. I think the speciality rotor only comes into its own in tough crops.

Specialty rotor is the way to go hands down in my opinion, especially with your crops. We do mainly corn and beans with a few acres of oats each year. Went from a standard rotor to a specialty and like the results in each crop much better. I think the oat straw is much more balable coming out of our spec. rotor now, sure has been the case with us the past two years. As for concaves and such, depends on the acres you do, but we leave the large wire concaves and bar grates in and don't use cover plates, get along fine for the amount we do each year, good sample, etc. There are quite a few people that I've come across that don't swap concaves back and forth as they are "supposed" to and seem to get along fine. All depends on if the acres you are cutting make it worth the cost to buy the other set of concaves and go to the effort to change them out.

little Onion- I have a 1460 for sale also an 820 flex head and 844 corn head always been shedded, if interested email me.

I agree. The specialty rotor is made to pull tough green crops through the cage and it is harder on the straw than the standard rotor. But if you have green stem or tough beans you should go for the specialty rotor and suck it up on the few acres of oats.

FYI, we have an alternative to both styles of rotor , we've built a couple of hundred of them and they have outperfomed OEM in any crop or condition. Saving straw not a problem.

What do you charge for one of your conversions for a 1660.

Field ready rotor with all components (impellers and wearplates, hardfaced rear strippers, new drive bushing kit, 3 spirals of rotor bars and mounts)is $2508.00. If you're harvesting edible beans we might suggest adding a 4th spiral of rotor bars leading the strippers -- additional cost $297.00.
