I have been running a 1660 for 4 years, and it has been great. I bought a 1680 this fall to run along with the 1660. Is there much difference with the 1680 other than more hp and a bigger grain tank?

The 1680 has a larger rotor and sieves. I'm sure there are plenty of other differences with various components, but those are the main ones.

Which 1660 and 1680 do you have? The IH engine or the Cummins? A 1660 with the Cummins probably almost has the same capacity as the 1680 with the IH. The 80 series is physically larger in almost every way and all thru the threshing area.

 

[nielreal]

both have the IH engines

If they're both in good shape, I'd take the 1680 every time

I have ran a 1460 beside a 1480. We went side by side down field doing equal job. Only difference was 1460 had 25' head 1480 had 30'. 16 series should be about the same I think.

This is similar to our experience as well.

I believe the rotors are the same are they not

 

[jesseb99]

Do they both have the standard rotor in them? If not that could be a big difference.

 

[okpanhandle]

I believe the rotors are the same are they not

24" rotor on the 1660, 30" on the 1680.

 

[nielreal]

they both have the rotors they came with from the factory

 

[okpanhandle]

jesseb99 is asking if they have the Standard Rotor or the Specialty Rotor, both factory options. The standard rotor has long, straight bars over the grates (3 on the 1660, 4 on the 1680), while the specialty rotor has short rasp bars over the grates.

The standard rotor is great in corn and small grains where conditions are typically dry, but struggles a bit in tough/damp conditions. The specialty rotor was designed to better handle tough, ropey crops like green-stem beans and rice. I haven't been around them very much, but from what I hear a machine with a specialty rotor will run circles around a standard rotor when things are tough.

I have finished now and the 1680 can put through at least 30 percent more
