We are running the harvest rotor 1st yr and it rumbles as much as old std rotor and no more capacity. Could there be something else wrong? Doin hard red spring wheat and our 1688 std rotor killin the 2388 in tough goin. Also got lots fines in the hopper close it down and it overloads return. I closed front of chaffer which helped but wont that effect capacity?

The front of the Chaffer should be closed tighter than the middle or rear sections for the cleaning system to work properly. It will not effect capacity but don't close it completely.

From what you describe the crop is staying in the rotor too long with the Harvest rotor and with the straight rasp bar design of this rotor that is what will happen. It will take more hp and over thresh the crop material putting more MOG on the cleaning system. You had better check the condition of your transport vanes and their position.
Question, do you have notched separator bars on your std rotor 1688 as you say it out runs the 2388?

My neighbor ran a Harvest rotor for 2 yrs in a 1688. His 1680 ran circles around it as soon as the sun started going down. Talked to Harvest guys numerous times with no solution. He pulled it out this fall and put a used specialty back in and is very happy.

bd polar wish i had that info sooner coulda saved me some $$$. Will give them a call about this tommorrow the claims were more capacity in tough goin. Shoulda went with the oem afx i guess.

The Harvest is heavier which is supposed to be better because of momentum and other salesman talk, so it takes more power to turn and keep going and more fuel. We grow lots of straw here and in oats he said it was like tring to push the swath through a rotating wall. The rub bar mounts and bars look like a good idea. I was with him when he bought it and we both thought it looked good but something in their front end and feeding doesn't work and they need to realize that and fix it.

i've been impressed with the afx's that i've put in machines & 1 machine they hated now they just love that machine. i understand the price of a afx is high but it works good.

Run 2 1680 equipped with harvest rotors and do beleive that the capacity is increased in tough conditions. Have not run side by side with standard but have run standard rotors and had them almost stand still once the straw got tough. It does seem that we do have to run alot of air to clean up the sample though. We have airfoil chaffers and always seem to need the fan at 850 to 1000 rpm. Use these rotors in peas, barley, canola and wheat.

We found the problem it was a broken 1st concave it finnally let loose put a spare in and seems to be back to normal again. ajl we run our fans 1050+ in wheat all the time
